Jason,

Have you set a date to hear them?  I will be VERY interested in your take on them.  Since I jumped on the high sensitivity train I would like to hear all of the contenders.  The SuperV's do have the advantage of the dipole servo subs, but multiple subs placed around the room to pressurize it is an interesting concept.

Dave

Dave,

I'm not sure they're such natural competitors, if there is such a thing with so many different tastes and all.  Tyson did a nice job comparing the V2 and Abbeys/ with 3 GR Servo subs at Mike's.  I actually mix both sub approaches in my system, using the Abbeys with a pair of the V1 bottom halves (servo dual open baffle) and a third sealed GR servo sub as the primary, with pseudo-random placement.  It yields smooth, quick, and deep response that integrates seamlessly. 

I was also amazed at the opportunities the higher efficiency opened up and like it a lot too    For example, the Dodd buffer with those battery mono's seemed like they could really be a really trick setup for not a lot of coin.

Should hear them in a few weeks or so.

Cool, thanks.  I've read all of the info that I can on his speakers, ideas and general approach to audio.  Haven't read the patents, though.

I have my work cut out for me.

I was talking in generalities about high sensitivity speakers in general and those with 12" drivers more specifically.  I like the concentric driver for the coherency.  Makes way too much sense.

I spent a lot of time with large Tannoy studio monitors and could live with them if I had to do so.  Those older drivers did not have the apparent "speed" of the newer ones like the ones used in the Super V.

I'll have to try the multiple sub approach if, and I should say "When", I ever get all of my projects done.  I've been so absorbed in work, church, family, remodels, illness and such that I have not even gotten my Super V's completed.  Some things just suck.

Yeah, I've got a whole pile of get 'er done's too.  I built new speaker stands so I could move the OB Servo subs to better spots and missed the music so much only one of them has veneer on it.  It's a good look, bird's eye maple/black walnut on the right, raw mdf on the left one    Now get to work on those V1's, you've been back home at least 1 day!

I used to have some preconceived opinions about Danny's speakers, but hearing is believing.  I haven't heard everything out there but at any given price point, Danny's work is very hard to compete with.  Based on my experience with his products GR Research is the only manufacture I could blindly spend money on with total confidence.

Taste varies in the hobby quite a bit, but I question a speaker that 'you have to get use to' in order to appreciate.  With time some people can be conditioned to believe anything...  But still I wouldn't mind hearing the Geddess speakers.

Well, I have seven boxes with the GR logo on them in my house and sawed the end of my thumb off making one of them, so I even gave blood    I'm very happy with their performance/value, as well as the support I've received to build them.

I can't recall ever living with speakers you have to get used to, but if I did, they'd be in the for sale bin quick enough

That's my point.  Excellence should be obvious to the ear, not of matter of conditioning and or marketing.

Man, I came home to 180+ emails, came home with orders and I am getting orders.  This is wonderful except for the fact that I can't get the kitchen done.  I promised Gayle that I would do so before I built the speakers.  I have been cutting parts as I get in table saw mode though.   

Time, time, time... All in its' own due time.

I don't get those comments.  There were some tracks that were played that are bright recordings (Christian McBride - NIGHT TRAIN - for example), but what I heard was digital that was true to the source data.  If the track was bright, the reproduction was bright.  Like I have posted elsewhere, I heard rooms, which will remain nameless, that are getting thumbs up on sound that I just don't understand.  I think it is like many shows.  There are those that found it bright and those that said it needed more highs.  Go figure.  We had many people that told us that we were the best sound that they had heard or at least in the top 3.  I thought that we kicked butt except for the rooms' limitations.  Gotta plug that hole, for sure.  I know that we were right "there" when it comes to sound at a difficult venue.

It is like mixing a martini, I guess.  Everyone has a different recipie.     You can't please everyone.

Dave

Nicely put.

[cujobob]

I see that you have been reading about the Geddes speakers.  I'm not sure about them since I have not heard them.  I kind of shake my head, too.  Whatever works, I guess.

Dave

Don't mean to de-rail the thread, but basically..using the foam makes logical sense and works wonders.  There's nothing missing in the top end, in fact, because of the lack of side wall reflection, the top end is quite great.  Some people will complain about the foam, but the same could be applied to using small drivers, full range drivers, off-the-shelf coaxials, etc. etc.

Danny's room is getting a lot of attention it seems...should have a lot of new visitors here at the circle.

I've used reticulated foam for speaker grilles.  Anyone remember the JBL speakers like the L100 with the sculpted foam grilles?  Eric Hider and I had this "whatever works is what works" conversation last weekend.

I do think that the Super V's sounded best with the grilles on.  The whole thing is a great topic for discussion.  I posted a link on my Circle about resonance that is relevant here, I think.  My thing is - everything effects everything.  Seems to be true in every aspect of the hobby/profession/obsession.  Gives guys like me a reason to live. 

Danny's speakers were and are great.  The cool thing is that they can be tweeked for every taste.

OH, yeah.  Mine are Super Vs'.  Rather, they are Super V parts... so for

I was in the GR room friday afternoon  and the sound was quite good. If it got better, that would be amazing. 

As for you'all waiting for "JA" to write a nice blerb about the sound in the GR room, don't hold your breath. He might have loved it but its more of a political football at his level in the press. They are tight lipped until you are committed to a 1/2 page or better asd package.  you also usually have to have a string of now endangered "brick and morter" dealers who advertise as well.

You will not be the first to

That why the Audio circle was created. Some things are too good to go un-noticed.

You pretty much nailed it. Here s JA's burp:/

I need to clarify. I knew the comments were yours. Sorry for the confusion. I was referring to no comment by JA on the sound of Danny's speakers. Yet, everyone that heard them and posted were blown away by the sound and performance per dollar.  Great job Danny. I want to hear these puppies one day. Are you planning on bringing them to Atanta next spring at Axpona? I believe the show is in April.

[dBe]

John is a wee bit of an audio snob and any mention by him at all is a kudo.  I added a comment below the post since he left my company unmentioned in the burp and added Mach2 (a guest, not an exhibitor) to the pablum.

The audio media at it best?

Which is why I posted my comments on how it actually sounded.

Apparently, I was mistaken on the price of the DAC? I checked DB Labs website: http://www.dbaudiolabs.com/ and the only DAC shown is the Tranquility model for $1,495. But the one used at RMAF is a new model called the signature at $2,395? 

[HAL]

The Tranquility Signature DAC is new and just shown at RMAF.  It is $2395 from what Eric Hider told us when John Atkinson was in the room.
