Well, this is a surprising addition to the line. Not my cup of tea, but I know there are many followers of this type of speaker. And in a small room with the amps built in, probably a stunning performer. Will be interesting to see how this performs from early adopters. Hope it's a success!

Wow. And I just earlier today pushed the button on my two other pairs of ERRs. I have to look at this.

Well, that is one impressive looking speaker. And I suspect it sounds excellent. Bravo Steve!

But…………. I think I am going to stick with the ERRs.

I'm curious how this speaker compares to some of the others in the Decware lineup.  I also just recently purchased the ERRs, and while I'm very satisfied with them, I'm curious how to evaluate the speakers against each other.

From looking at the drawings from the DNA paper, the entire speaker is listed as being approx. 28" tall.  That's crazy small, should they be put on center channel stands to get them up to ear level, or will they work as is?  

Assuming one is using the Torii Mk III and a CD player to drive the speakers, can you compare/contrast the MG944s, ERRs, HDT, and DNA speakers?  How should we select between so many good options?

It's almost embarrassing to say this, but I've been wanting to do a video A/B comparison with all the Decware speakers for over 2 years already....  and will the first weekend I can steal two days of solitude...

I've learned from watching some of the CES and Rocky Mountain show reports on video that you can hear almost more about the speaker through the video sound track than in person.  

Until then, I'll give it my best shot at a simple explanative description of the speaker's sound.

DNA - This is the least efficient speaker we've ever done. Too low in fact for a long term relationship with a 2 watt Zen Triode Amplifier. So why go there... because in this case the sound is so unusually good that it's worth it.  6 watts will fill a healthy size listening room with good density so we felt it's still a go.

Of course with the lower sensitivity comes the smoothest frequency response of the Decware line of speakers.  It's just flawless and shout proof.  You get the forgiving nature of a less sensitive speaker with the attack and detail of a high efficiency speaker because the moving mass is only 7 grams and it's fully horn loaded.  Kind of the best of both worlds really.  Also next to the FRX driver, the most advanced and expensive driver used in a Decware Speaker.


MG944 - By comparison a pretty significant jump in volume compared to the DNA, around 5 dB.  And while the MG944 are one of the smoothest speakers we make, they come off a bit edgy by comparison to the DNA when listened to on a less than perfect source material.  Again ironic because you actually hear more detail from the DNA.  And while famous for it's deep bass extension the MG944's are unable to outperform the DNA until you reach a higher power level at which point you have a speaker that can clearly get louder and hold together under stress.

The imaging between the two speakers are equally focused and while the MTM arrangement of the 944's always had the best and most pin point image density, the DNA is slightly better and when you get your head out of the vise - really better.  Image depth is prominent throughout the listening space, not just an effect heard in the sweet spot.  In this respect they are similar to the ERR's which are a radial speaker.  Image height and width are better with the DNA despite being only 24 inches to the center of the driver vs, the MG944 being probably closer to 38 inches.  This is with the speakers flat on the floor and of course both can be tilted back to further enhance this effect.

The HDT is conservatively rated at 96dB and has similar speed and attack to the DNA so it sounds like a DNA on super juice.  Gets loud, handles power, and by far has the most presence giving music the most slam for it's size.  Great bass, plenty low, tight.  Although not quiet as extended as the DNA and perhaps a bit harder to set up, it is the clear winner when you want to hear music sound loud and live on lower power amplifiers.  All else being equal if the DNA driver had the same efficiency as the HDT it would probably  embarrass it pretty bad.  If I want to hear changes in an amplifier during the voicing phases when trying different capacitors and resistors I use the HDT's for their unusual honesty and presence.  I could easily use the ERR's or MG944's but it would just take longer.  Instead of hearing what I did in 90 seconds it would take 10 minutes or more on the other speakers.  DNA could be an exception, haven't tried voicing an amplifier with them in the mix yet.

ERR - The most laid back presentation of the group with imaging as good as the DNA but from almost everywhere.  By far the easiest to set up and the hardest to make sound bad due to the impossible to collapse 3D imaging and the warmer bottom they bring to the sound.  The ideal speaker for bright rooms, and the only one I would recommend besides the DM945's and now the DNA's because they're just so smooth it's going to be hard to aggravate their sound with a bright room.  Got glass, get ERR's and through the magic of a radial wavefront make it actually work for you rather than against you.

Would there be an advantage to flush mounting the driver, like the change done to the DM944?

My plan was to flush mount it, and same with the ZOB's new FRX driver, however after measuring the response I felt it wasn't needed.  I'd say it's a cosmetic issue in both cases and I'm not sure which I would actually prefer.

Hi Steve! long time.  

The obvious question is if you will sell the cabinet plans for the DIY crowd?  

Second question which is prob a stupid idea but I'll ask it anyway... given the size of the baffle and "compression chamber" could you use two drivers to increase the efficiency?  I know the cabinet internals would prob have to be tweaked a bit.  I've heard people talk about the cancellation effects at high frequencies - creating holes in the imaging - but then I've also seen speakers like that which shouldn't work but do.  Eg, I was just reading about the Clairaudient 2+2 which uses two 3" FR drivers and has gotten almost unanimous praise (at the shows at least).  So what's the story here on the cancellation thing?  Is it just getting the spacing between drivers correct or does it also depend on the distance of speaker to listener?

[edit] forget the Clairaudient comment - I just realized it uses two front and two backward firing drivers in addition to side firing mid-woof (10 total drivers!)... so Omni-directional prob has big effect on that one imaging.  But the question about two forward firing drivers and cancellation effects still stands for the DNA - could it work?  And/or would it require a completely new cabinet design?

[edit] example related to my above question (this is not the DNA! Smiley ) LOL...



Btw, forgot to congrat you on a design that I'm sure sounds very nice. and sorry if I led this thread astray a bit.

Steve's summary description above is very helpful; reminds me of the "which amplifier" guide. Would love to see a video A/B/C/D comparison of the speakers. After mine are built, of course. Wink

Efficiency isn't the ultimate goal with this design.  It's sound quality, imaging, and bass extension.  If I were willing to have weak bass response that becomes non-existent below 50 Hz,  I could easily get a sensitivity of > 95dB with a different driver, but it would be a crime in this enclosure design to not make use of it's impressive low bass potential.

An interesting design. Kind of reminds me of some of Bud Fried's work.  Zen Fest is going to be very special this year.

Speaking of which, has anyone heard/seen any announcement or plans for ZenFest?
