Hey Brad,

Glad to hear they're coming.
Please post impressions ASAP!!! (I'm especially interested since I plan to add the Aurum tweeter to the DFR8 )

We'll be waiting with, as they say, baited breath !!

Cheers, Bill :D :

Got them in just now.  That is the most serious job of packaging I've ever seen!  

You know I'm gonna throw them bad boys in the HDT's... like tonight!

fun, fun, fun....

I'm gonna break them in and do all auditioning without having my ribbon tweeters hooked up.  I want to become fully accustomed to the sound of the DFR8's before I ever listen with the tweeters. That way I can tell better if the tweeters make the DFR8's sound better, worse, or if they are just not needed at all.

I can't imagine the highs will be improved in the range yourr running your Aurum Cantus Brad. It's likely you still dig the ribbons in. Betcha a saltine craker  :)

Yeah, Chris, You're prob right.

Btw, many that's quite a speaker collection you have...
The MG944's, Hawthorne SI's, and Ed's Horns.
I know what the Horns sound like, but how do you like the SI's and MG's in comparison?

thx, -Brad-

Hey Brad,
Yes my speaker list is growing.
While the Horns do some amazing things in imaging and midrange they are not my favorites at this point. The MG944's do just about everything right but maybe not as "clinical" as the HDT's. I do want to have HDT's in the house also. The SI co-axials are a very nice sounding speaker but I have yet to get them in baffle so there is not much I can say. Down on the floor though they cast a tall deep image/sound stage, and that makes a strong case for JohninCR's diminutive "Joint Chiefs" project. I do have another pair of prototype speakers that have the 6" Fostex drivers (2 per side) and they also have a wonderful presentation and presence that none of the other speakers have. I like em all. The Horns are for sale though. MG's and SI are keepers.
I still have a long way to go especially with my source..

BTW brad would you be kind enough to PM me (or post) the link to the case you selected for your "Charlize" amp?

I've been listening to the DFR8's with my Charlize amp connected direct to my CD player.  My TABOO and CSP is still over my friends house.  The HDT's with the DFR8 drivers still sound quite bright sounding - not very acceptable IMO.  I'll have to see how much of this is due to the sound of the Charlize, the breakin  of the DFR8 drivers, and/or what happens if I was to (1) use the TABOO instead of the Charlize, or (2) put the CSP preamp in front of the Charlize.  My impressions so far of the Charlize is that it is a brighter sounding amp than the TABOO and certainly the Zen CS. This is not unlike what I heard from the Clari-T (another Tripath chip based amp) to sound like.  This would explain why a couple people I know who like these amps have them mated to full range drivers that have a rolled off high end (IMO) due to not having a whizzer or a separate tweeter - namely the B200 and the Fostex F200A.  Keep in mind that my room is very "alive" not having allot of reflective surfaces (no carpeting  of any kind for example) so I think it's a brighter room than your average bear.

Btw, If I were you I'd build the Manowar Sonotube baffles for the SI's.  I think they look much better than the Joint Chief baffles and are much less obtrusive looking compared to large flat baffles. I can't speak to how they sound though I would imagine it's prob about the same as other similarly sized baffles...

Here are some DFR8 pics.
While I had the drivers out I made a small cabinet change to help reduce cabinet resonances. I added a small piece of Deflex panel dampening sheet just behind where the driver sits.  Not sure what   audible effect this really has, but it can't hurt Smiley and it only costs ~$15 for both speakers - one 12" deflex sheet cut in half.  The picture was taken before I put the foam back in place - the piece that goes just below the driver. The black gunk left over from the driver sealant/putty-stuff is easily cleaned.  Btw, my drivers didn't come with that driver sealant "rope putty" - luckily I had a couple in my box of audio junk that I never throw away.  The ribbon tweeters sitting on top of the cabinets are not hooked up.

Nice pics Brad, and thanks for the first impressions. Just as a side point, You used silver hookup wire in your charlize yes? A few have noted that the silver wire is brighter than copper, with the majority feeling that copper gives a smoother sound. Smiley

Hi Brad
I did the foam surround mod only on the black FE206EM's about 10 days ago.
Straight back into the box I heard
1. Increased bass punch
2. The little bass bloom at 20hz ( that appears in the article graphs) is gone so that made the sound lean at the bottom. Installing the alternate tuning extension tubes bought the bass back up nicely and made the whole bass presentation much more even.
3. Good recordings are better. Bright and edgy recordings are worse
4. The lower mid-range is glass clear and more detail is apparent.
5. The upper midrange is brighter and vocal sibilance is now more pronounced. Some recordings are now borderline listenable. Getting rid of female vocal sibilance is why I got out of solid state and complex speakers.
6. The brighter sound has helped my vhf tuner which sounded a little laid back before
7. The brighter sound has not helped my njoe tjoeb when a bright cd is playing
8. I believe that the brightness has decreased about 10% since I first installed the polyether surrounds. Perhaps it will continue to improve?
9. I've tried various bits of damping around the phase plug and whizzer but they seem to affect other things so I've ended up taking them out.
10. With good source material the clarity of the new driver is very good. If you only played top notch vinyl then you'd be laughing.
11. Are they better speakers? My only concern with the HDT's has always been their amazing clarity ( It has helped me when modifying the Zen ) and slightly forward upper midrange. This is not unusual in FR drive units. Everything else about the modded drive units is better except the bright upper mid-range, which now appears much brighter.
12. All of this needs to be veiwed in the context that I installed the surrounds myself. Therefore my implemetation may have affected the result.
13. On any given day when you fire up the speakers from cold they change markedly over the first 45 mins.
14. When all is said and done these are High Definition Towers! We got what we asked for, we may not like all of it.
Cheers
Steve

Yeah C, My buddy Steve and I thought about this. We have some Cardas copper litz wire on order for building the second Charlize (which we have all the parts for).  Then we will compare the two.


Steve, thanks for your feedback.  I still think that the Charlize is a big source of this brightness, and to a lesser extent, my room.  I tend to discount the room effect because when I listen near field it's even brighter!  I'll make conclusions when I get to hooking my TABOO+CSP back up.  For now, the Charlize is serving to break in both itself (it's got maybe 200 hours on it now) and the DFR8's.

Thanks for that info Brad. I am going to Modd the thing, I am now developing a plan of upgrade, but I want it to include a better source switch, volume control and better RCA's, or maybe a different type of connection for the IC's. With your cap upgrade did you notice a detail level increase?

I imagine that the DFR8's will take as long as the orig 206e to break in....and be very sensitive to the amp used.  

When I got my 206's two years ago, I'd turn on my tuner and amp while I was at work for 2 months.  It got better, but it wasn't until late last year that I really started to get smoother response and good bass.

Well, the DFR8's seem to be breaking in nicely already.  Everything is slowly getting smoother and less bright.  Even with using my new chip amp.  I still haven't gotten my TABOO back to try. I'll let y'all know when I do.  Maybe this is helping the breakin though. Sometimes when I go to work I'll leave a CD playing - cranking pretty loud.  I can do this with the chip amp and don't have to worry (it runs on 12 volts) like I do with my tube gear - plus it's more than twice as much watts.

Sure. Btw C, have you ever thought of adding a super-tweeter to your B200's?  I bet the Aurum Cantus G2Si ribbon tweeter I'm using would improve things for you quite a bit.

Brad I have thought about it. I have a pair of Hiel Air motion tweets. There is only 1 song in all the songs I play, that ever has me thinking about it though. But as you say it may be of benefit. Something worth trying at some stage. Did you notice any down side to adding a tweeter to your HDT's.

No.  But you have to cross it high enough to keep it from messing up the main driver.  If not you're liable to get peaks in lower treble and a potentially bright sound.

Besides the obvious benefits to drum cymbols and plucked instruments I noticed a big difference on bowed instruments, particularly cello.

I have  to echo brad's sentiments  on the  Aurum Cantus ribbon. Mine  have  been in just a  hair  over a  month  now.  The only weakness I was experiencing early on (a  little too much sibilants, especially on female  vocals) has  now become very tame. Some of this may  have  been tube-related.

I  normally change  power  tubes every six months  like  clock-work, they  are  cheap  enough, and I  like's  'em  fresh.
I  had a  set  of the Russian Military  6N15Ns, and liked  them  so  much I bought a case of  50 @ $2.16/tube.

Anyway...  they  had  been in  only  about  4.5  months,  but I  had  been running them  very  hard, and  leaving the amps on constantly. A fresh set of tubes made all the difference  in the world !

I am ordering DFR8s tomorrow !   :
From the sound of the  feedback I'm  hearing, I  will be  burning  them in for some  time (good  time to  re-use the  4.5  month old  tubes).


Brad,  have  you  used the  ribbons with the  DFR8s  yet ?

You MUST send them in for a good Cryo treatment - it brings these tubes to a completely different level.  We did a group Cryo  buy/treatment a while back on these forums. Everyone really liked them including Steve.

Yes, I have.  There is less of a need for the tweeter with the DFR8's to my ears.  The ribbon still adds something, but with the DFR8's I don't miss the tweeter when not hooked up as much as I did with the FE206EM's.  It may have to do with the fact that the DFR8's don't seem to need felt around the phase plug to mellow out brightness the way the EM's did.  

The DRF8's (and my chip amp) are breaking in nicely.  The brightness initially heard is mellowing out.  Bass is still lacking - it could be it takes longer for the surround and spider to break in.  But again, can also be largely due to my "live" room.  More time will tell.

I have 16 of them being treated as we speak :)



Another interesting thing you might want to try:
Mount the ribbon facing the rear, and wire it out of phase.

I'm sure this 'rear ambience' effect would work better if it were mounted IN the cabinet, but I like the effect a lot.

Hello Rob,

Wait till you hear the cyroed versions. Unbelivable!!

BTW, if you don't mind, where did you source a case of fifty at that price.

Also, do you have a tube tester to match your pairs, or do you find it's not an issue.

Bill...
The  seller  was the  same  one on E-bay who is  selling the  cases  of 50 on E-bay at the "buy it  now" price of $175.  
At  first  he  did  open auctions  on these  cases, and  I  lucked  out on  one that  ended at  like  3 in the  morning with only  one  bid  ahead  of  me. I  got  it  for $108

I  do  not have a  testerand  have  never  matched  tubes  in  my pair  of  Selects. It's never   been a  problem,  unless  one of the  tubes is  bad, or at  least way off  from the  other, and that  has  only  happened 2-3  times in  5  years.

It sounds great!  A little more efficient, more midrange detail (as if there wasn't enough already!) while still sounding smooth and not bright, midrange is more "juicy" for lack of a better word, and a hair better bass. Only downside I can see so far is you lose allot when not seated unless you're clear accross the room.  Putting something under the fronts to tilt them back could help that.

While these are not large enough for a "true front bass horn" I think they are helping the mids my compensating for some baffle step loss.

The "Target bowl" tweak is reversible/non-permanant. I used double sided aggressive out-door tape (the kind to stick address letters on a house) to affix them.

Btw, you might think I'm goofy, but this really does improve the midrange quality and "juicy tone".  I'd love for somebody with a less live (better treated) room to try this and let us know how it sounds - especially the imaging.  For me I don't lose anything, but my room is not the best for discerning imaging details.

Bottom line is I was walking through Target the other day and when I spotted these bowls, I thought... hmmm... interesing profile... and man that diameter looks close.  Then when I grabbed a tape measure and saw it was 8" I had to take one home to try out.  I cut the bottom out with a razor knife, and listened to it on just one speaker, listening mono, and switching back forth to compare to the other without the bowl.  Things sounded promising and I didn't hear any major problems, so I bought another bowl to audition in stereo.  Well, I don't think I'll be pulling the bowls off any time soon - except maybe to silicon them in place permanently.

I'm lovin' it even with my Charlize chip amp.  I'm really chompin' at the bit to get my TABOO and CSP back from my friend!!!

One of those accidental discoveries.  :)

C, sure I can send you a couple if you can't find them over there.
But what is the size of your OB?  If they are pretty wide/big, you might not hear much of a difference with the TB's.  Unless there really is some horn action going on.  But even if that's the case, they are too small to be adding much bass, so It's a crapshoot if they will make things sound better or not.  In any event, they're cheap enough to try just as a fun experiment.

You may already know this... ideally you want curved walls not straight. I think you can get honky/resonances with linear "horn" walls or walls curved the wrong way (bowl as apposed to bell shaped).  

Btw, this should be a separate thread. Really not specific to DFR8 drivers.

cheers, -Brad-

Don't bother searching for it online. It's not there.  I called Target and it cannot be purchased on their website or by phone. Go figure!  It *is* sold in all their stores under the name Zazen bamboo tray.  Target also does not ship internationally - unfortunately.  

Btw, the bowl bases can varry in diameter as much as 1/8".

Re: DFR8's --> Steve, where's my commission?
Reply #49 - 06/12/06 at 07:26:03
 
Well, I may have unintentionally just sold a pair of HDT's for Steve and possible and CSP to boot.  Steve, where my commision? Wink

My buddy Steve and I had a mini listening session. He already had my CSP hooked up to his Art Audio Carissa amp. I brought my HDT's over his place today and left the for a while.  We gave a listen to a few disks on different combination of equipment.  The disks were good quality recordings, not awesome, but just good.  I forget the album names but Steve pulled out Natilie Merchant, Aimee Mann, while I had brought some of my current favorite Marcio Faraco (Brazilian jazz) 'cause I thought Steve would like him, which he did.  We had limited time so we focused on changes in equipment and listening mostly to Faraco.  Equipment listened to:

Speakers: Decware HDT, Reference 3A Royal Virtuoso
Amps: Art Audio Carissa, Decware TABOO, Charlize DIY chip amp
Preamp: Decware CSP
Source: Sony 9000ES w/Modwright mods
cabling: All cables were expensive looking snake-like beasts - I didn't enquire about their brands.
Room: No treatments, approx 15'x15', listening at approx 8' triangle, toe'd in pretty much directly at the listener.

Sorry for the quality. I snapped them with my phone... thought some of you might find them interesting...

my comments in short...

Ref 3A Royal Virtuosos: good sounding laid back sound, surprising bass for bookshelf speaker (though this *is* a small room).

HDT w/DFR8 drivers: Note the DFR8's are still not fully broken in.  On all amps including the Carissa we both thought the HDT's sounded better than the 3A's. Way more midrange detail, better bass, more "you are there" presense. I already kinda knew what to expect.  Though I wish I could get the bass we heard in my MUCH bigger room.  In this small room, the bass was not lacking at all.  Def no need for a sub.  Notable comments I heard from Steve, were... "they remind me of Quads in a way"... "wow, that's freaking awesome!"(that was with the CSP,  HDT+Carissa)...and..."that's the best sound I've ever heard in this room".  The treble did not seem to be lacking at all.  A helper tweeter does not seem to be needed with the DFR8's the way that I felt necessary with the FE206EM (with felted phase plug).

Carissa:  In this room, with this equipment, I preferred slightly the sound of the Carissa + CSP.  I just wish it didn't cost $7000, ~ 10 times what the TABOO costs!

TABOO:  (cryo treated SV83's and cryo Sovtek 12ax7-LPS) The sound was very good, approaching the Carissa in most ways. We both thought the bass with the TABOO was better than the Carissa - which really surprised me (it's an 845 SET).  I liked the mids from the Carissa a little more.  There was a problem with one channel distorting when we turned the volume up.  I swapped the power tubes and the noise followed, so it looks like one of the SV83's was bad and I didn't have a spare.  With the volume down it still sounded very good.  Steve said he could difinitely live with this sound.

CSP:  Not much to say. It made everthing sound better except the Charlize.  Not much difference there.  Could be I'm using all cryo treated Sovtek 6N1P's.  Maybe tube rolling (6922's?) would help?

Charlize: For the price the sound is quite good, but some brightness and listener fatigue there.  CSP smoothed out slight graininess but didn't fix the upper mids brightness.  IMO a great second system amp but won't have me selling my tube gear.  I've heard this amp sound better - with my DIY K-slot horns.

I hope someone finds this info interesting.

GL out.

Btw, Amoung other things, I really like the treble of the DFR8's better than the old FE206EM driver.  I feel there is much less, if any, need for a helper tweeter now.  

Kudos to steve on the phase plug improvement!

I certainly did.  I would like to try the DFR8 in RCAfan's K-horn.

Yes, that would be interesting.  Maybe I'll try that out some day.  But the older FE206EM's sound pretty darn good already in RCAFan's K-slot horn.  And not only am I a bit lazy to try it right now, but every time I pull drivers from the HDT's I need another pair of the "rope calk" driver gasket material.

Let us know if you ever build them and/or try it out.  I'll do the same.

That much I knew.   Grin
They are tiny, the ones around here are black,  They get in my ears when I am trying to fish in summer, and you can sometimes imitate them on a number 22 to 26 hook for trout.  
That is as much as I know about it.

Hello Brian,

You want to catch more trout? (stupid question)

Tie your gnat imitations on a 28 or 30 ring eye hook.(TMC makes em, style 300).
Use a little wisp of black CDC. 8x only and NO FLOATANT.

Happy fishing. :D

Bill

Think self deprecating humor.  At one time I was the posting leader on this forum. Don't know if I still am.  

Gnat-one to Gnat-Leader... cover me, I'm going in.

actually, I think Randy has had me consistently beat.

yowza!  You guys must have been on page 2 - I didn't see. Anway, the name really came from a guy and I at work that call each other on our badges (we make hands free wi-fi communication badges; voice-over-IP; think Star Trek communicator) and we would call each other jokingly like ... "kssshht.... Gnat one to Gnat Leader... over" Smiley

I did the double suspension trick today to my fe206e.

I was to lazy to remove the drivers. It's not an easy job but I had experience with the passive installation in the hdt.

My hdt are the alternate tuning ones using whizerless driver and amt-1 tweeters.





It's pretty fresh and probably too soon for evaluation but so far it's a slightly different driver than before.

The mids is less forward and may have less energy but it seem more balanced with the rest.

The bass seem cleaner and slightly more present.

I can't speak for the highs because I'm cutting them at 8khz.

I'll wait some weeks to see what happen. The membrane seem pretty stiff for the moment added to this that the drivers are still pretty new.

I don't know if Steve will be selling the new phase plug used in the DFR8, but if he's willing I would recommend it for those DIY'ing their drivers.  The DFR8 has better treble response then the old FE208EM and does not require felting the phase plug to reduce the slight brightness.  Now, I can't make any claims for how it works in a whizzerless driver... that's a whole different animal.

I also have a pair of decware fe206em.

Those with the new phase plug but without the double suspension (bought in january)

My original pair of fostex with some dynamat on the basket and the diy phase plug are almost impossible to discern from the decware driver.

I'm not sure that the form of the new phase plug have a lot to do with the sound of the new dfr-8

Well the cabinet could be playing a part.  All I know is that for me, in the alt-tuned HDT cabinet, the new DFR8 sound to have more extended treble, or better dispersed perhaps.  However, I will say that the DFR8 was not fully broken in, so it's bass would have been less perhaps making the treble sound more pronouned.
