Question on the new HR-1 Loudspeakers
01/08/13 at 05:21:37
 
I am in the process of researching a new pair of high efficiency speakers for now.  After I read the product description, I still have some questions.

On the HR-1 :
1.  Does the vertical (ear level) listening position matter ?  I read the long paper on the website but not quite get it....the horizontal gap opening on the top of speaker, is that the optimum height for the ear ?

2. The front speakers....it kind of imply a traditional listening window in space, does it affect the radial pattern in a negative way ?

3. What is the -3db response on the low frequency in a typical room ?  I think the speaker bottom radiator is ideal for bass.

IF the speaker is more efficient......but there are a lot of air to move inside the speakers !

and last, a stupid question.  for orchestra symphonic recording, is the HR-1 better or the ZOB ?  just when I thought the ZOB is ideal, now here is the new HR-1.

Ken,

Welcome to the forum....Some interesting questions for sure!

[quote]1.  Does the vertical (ear level) listening position matter ?  I read the long paper on the website but not quite get it....the horizontal gap opening on the top of speaker, is that the optimum height for the ear ?
/quote]
Like any other speaker the HR-One's has a vertical axis sweet spot, it's just much larger than a conventional speaker.

[quote]2. The front speakers....it kind of imply a traditional listening window in space, does it affect the radial pattern in a negative way ?
/quote]
Like the answer to your first question, Yes it has a "typical" listening window, its just much larger. Say from just below the front woofer to standing, all sounds the same. There is no negative effects on the radial pattern, the drivers are seamless (which was one of the hardest things to get right) you won't even notice there is a radial driver, or a front set of drivers, they are that seamless.

[quote]3. What is the -3db response on the low frequency in a typical room ?  I think the speaker bottom radiator is ideal for bass.
/quote]
There is no "typical room". Every room is different, dimensionally, furniture placement and quantity. With that said mid 30's would be typical in a decent room.

[quote]IF the speaker is more efficient......but there are a lot of air to move inside the speakers !/quote]

Efficiency has nothing to do with box size, per say. Box size has more to do with the bass alignment for the flattest bass response.

[quote]and last, a stupid question.  for orchestra symphonic recording, is the HR-1 better or the ZOB ?  just when I thought the ZOB is ideal, now here is the new HR-1./quote]

Not a stupid question in the least. Being the proud papa that I am, I would reserve my opinion on this. More so because I'm not a open baffle fan. That is just me however.  If you are on the fence about either speaker, the best thing to do is call Steve and talk it over with him. He is great at finding the best match for your room, and personal tastes.

Hope this helps...

Thanks for the quick reply.

I read the posted paper about the radial speakers idea.  The most interesting thing is that, you are solving the problem of sound reflection of the room that distorts the music.  It is a system approach in engineering sense, not just a better cabinet, or a fancy driver.

One frustrating thing in orchestral music listening is to differentiate the different instruments.

Room reflection is physical, a real thing.  Spending $ on room treatment, it will be never ending.  Just like you said, there is NO typical room.

Thanks again.  I hope someone will post a review soon.

Buy these speakers you will not regret it. Wink

FWIW my intuitive opinion is that these speakers initiate a wave front not unlike that of the human head.

I have listened to HR-1's back to back with ZOB's. To my ears there was a huge difference. The ZOB's are very clinical and unforgiving, very accurate. The HR-1s have quite a bit more "sparkle" on top, something that I personally am a sucker for.
I always point out that my hearing is shot and my taste in music is quite different than most people. So listen to both and make up your own mind.

Donnie have you only heard them at Decware?
If so, when you finally get your pair in your home there will be differences. They will not be subtle and they will be all plus. Or should be. Steve's studio space is quite large when you include the boundaries into the bench area and the walkway to the door and high vaulted ceiling being open most notably to bass. The acoustic space that the low bass sees is much larger than the floorplan where the couch sits. The bass response in my living space is "subterranean" compared to Decware's room with just the two HR1s. No sub woofer needed in house for pipe organ notes soundtrack "bombstics" and the like. ROCKS the room but not boomy.

Thank you gentlemen for you comments.

to Chris K : Are you driving them with the Decware 2w or 6w amp ?

One thing I am looking at Decware's product is quality power, a few watts from Triode amp, what on earth can we drive ?  10 years ago, I was brainwashed into hundred watts of amplification.  Now, we are lucky to have full range speakers that are efficient.

Book shelf speakers are good, but bass is bass.  I supposed bass frequencies need a box to resonate (I could be wrong).

To Donnie :  Does the ZOB sound 'smaller' than the HR-1 ?  I supposed if there is more bass frequencies present, the lower amount of volume to hear (feel) the music.  Otherwise the ear wants 'more' for information, and it is natural to turn up the volume.

But the ZOB, with that specially tuned driver(to compensate the back EMF distortion ?), is almost ideal in theory.

I read the links in the msg.  Amen !

Forgot to ask Zygi : Which of the Decware's amp drive HR-1 best (except the Torii mono) ?  

The mini Torii has 4w per channel,  and the Zen Triode has 6w.   Or Zen Torii for more power reserve ?   I know quality does not necessarily equal to quantity.  Any subjective opinion ?

Ken I have driven them with an older version of the Decware Integrated 6 watt amp producing around 6 to 7 wpc. I can tell you honestly that respectable volumes and bass output is excellent. The speaker has the drivers loaded so well with the cabinet volume and passive loading that the drivers barely move at 34-36 Hz. That is DEEP bass. The extention of usable in room bass is down into the high 20's (28 maybe). All I can tell anyone here is that these speakers give you rock solid harmonic and tuneful bass extension that you just know it when you hear it. Yes 6-15 watt tube amps do well on this speaker. But you can give these the full force of a 100+ watt solid state or 35-60 watt push pull tube amp and the micro detail and dynamic all remain intact but the slam factor and big dynamics increase many times. TORII MkIII sound big on them though I dont have one myself. I am running many different amps on this speaker with the Decware CSP2 preamp in front of them. A bone stock Dynaco ST70 sounded simply delicious. It depends on what you want. Total transparent soundstage and imaging of low watt Decware single ended amplifiers is hard to match. Take a long time to find amps that do it without spending thousands.

Lets not forget all the other fabulous qualities that make HR1 a pleasure to listen to. Soundstage/imaging champs! Mid-range tone and timbre so smooth. Wide envelope of sweet spot to listen in. Top end sparkle that don't bite you in the ears. Work well with lots of electronics. Stunning looks. Guys behind it LOVE their work and care about customer!

Ken,

Of course, how loud you want to listen...With the Mini Torii I can get right to my listening level, it's just enough, no headroom for some really low bass if I wanted to get any louder.

Torii-MKIII as loud as you would ever want to listen, period!!

But my favorite other than my original Blue Torii, (I only had a chance to try it out at Decfest this year) was a pair of  bridged Super Zen's and a CSP2 in front of them. The amps were brand new, as well as the CSP, it sounded awesome.

However, in Steve's room, as large as it is, may also been lacking in power. Where as the Torii-MKIII is more than enough.

I listened to both the HR-1s and the ZOB's behind a Mini Torii. For the volume levels I like, the Torii MKIII is the only way to go.
Man, I wish the economy would level out for a few months, I will drop the hammer on a pair of Koa wood HR-1's so fast it will make Zygi's head spin.

After emailing back and forth with Bob about his "baby," I pulled the trigger last night. It came down to a pair of the Teresonic Ingenium, for which I had all but written the check, or the HR-1. I doubt I would be unhappy either way, but I also believe I chose wisely. Lord knows my wallet thinks so.
