But didn't you thank Charles for lending his home and stereo in the development?

Jim

I have on other occasions ..just not on this particular thread.
Charles is someone who I met at last years CAF and have developed a friendship with over the past year.
He is a very kind and helpful person and truly loves music and is very adept at putting a good sounding system together.
 His positive posts regarding GTAW have come from enthusiasm for
my speaker..he has no financial stake in them.

Don't sweat it Greg, I wasn't referring to you in particular anyway. Just a general burn-out moment that I had.
I'm over it already. See? 

Carry on men! Sorry for the trouble.

Are the GTAW speakers going to be at the DC audio show?
If so, please feel free to post the particulars here.  I'll swing by and give a listen.

yes...I will be co exhibiting with Charlie of Swap Meet Audio and Pete of Triode Wire Labs room 817
Please come by ... bring your Vinyl or CD's and  have a drink and a chat...Greg

I heard from Jack Woo regarding the WEE/Stax low powered amp combo:

Electrostatic amp is measured by voltage output unlike a dynamic amp. The
WES has a great swing voltage of 1300v. All Stax amps have roughly 800v
which is a limiting factor to the performance.

A WEE can work with a  power amp that outputs 3 WPC. However, a 5 WPC is
recommended to drive Stax headphone effectively.

And according to their spec-sheet - their ribbons are only rated to 28KHz (not 40KHz)?  So their HFs won't be as good a s a true-ribbon Maggie.

Dude, if you can hear 20,000hz, let alone anything above 20,000, you are super-human.  I don't believe anyone on the planet can hear anything close to 30000 or 40000 hz.  Speaker companies who list this range do it for marketing purposes.  There is no audible music content at that range because people can't hear it. 

A dog or a bat can hear these high frequencies but I assumed your comments were meant for humans. Dogs and bats don't have the cash to buy speakers anyway.  Even lower cost ones like MMGs.

Cheers

I suggest you need to think holistically about what you said, jackman.

The issue is not about whether you can hear over 20KHz ... the issue is ... can you hear the result (with, say, hearing that goes up to 15KHz) of a low-pass filter being applied to the signal at 30KHz ... or 40KHz ... or even 80KHz.  Because instruments like cymbals - with a fundamental at, say, 12-15KHz have harmonics which extend to well over 100KHz ... and once you strip off those harmonics ... a played-back cymbal no longer sounds like a cymbal in real life.
 
Or get hold of a cheap tube amp which probably has an upper roll-off of only 30KHz (because it uses a cheap output transformer, because it's a cheap product) and compare that - for cymbal sound - against just about any decent (and cheap) ss amp ... whose upper roll-off point is probably 80KHz, at least.  Again, you will hear the difference in "air" on the cymbals.

FFS, instead of regurgitating theory ... why don't you try some experiments.  Get hold of some smaller Maggies whose mylar-based tweeters are specced to, say, 24KHz (MG-1.6).  Put them into your system (assuming you have an amp which is capable of driving them) and see what you hear.  Then get hold of some 3.6s, whose true-ribbon tweeters are specced to 40KHz ... and see if cymbals sound better.


Regards,

Andy

Andy,

You're making the assumption that an audible difference between the ribbon tweeter and quasi-ribbon tweeter is because of their extended high frequency response.  I believe there's more to it than that. 

If you low-pass filtered the ribbon tweeters so their upper end roll-off was identical to the quasi-ribbon tweeter they'd still sound different.

Cheers,

Dave.

   My interest in the GTAW speakers started at the 2012Capitol Audiofest. They did things other speakers in my experience did not. The system used was holding it back IMO. We sell another brand of panel speakers that are similar however 4x the price. At the price offered during the show the GTAW seemed to be kaboom for the buck. So the interest started for personal use. After my in home demo I was very impressed so I asked Greg if he would be interested in sharing a room with us.
    Greg and I were curious to hear his speakers with different amps and systems to learn and revise the speaker accordingly. We tried several amps, preamps and sources. No combo disappointed. From 18W SET to 1000W of class hybrid class "D".
     Every now and then a product comes along that challenges the mainstream products. Well IMO this is one of those products. So my excitement. No one is claiming that "they blow away maggies", "the only speaker to buy", "the best", or anything like that. All I'm trying to convey is if you are a Maggie or planar owner give the GTAW a listen. You may be pleasantly surprised, especially with its bass performance.

What are you missing?  To find out, listen to the Manger demo cd on your maggies at a loud volume then go listen to the cd on a pair of speakers like the Revel Salons or Studios.  I think the shortcomings of planars will be self-evident then.  I love what planars and electrostats do within their limitations with classical and acoustic music, but they can't move enough air in a large room to give you the thrills and chills like top shelf cone speakers.  Move your head 6 inches away from the sweet spot and your planars now sound like Bose!

awesome demo cd...track 15...shakes my windows and rattles my a/c vents ..track 13..drum hits..yeah baby !!!
Think planar large driven area bests cone in a box squeezing music thru tiny voice coil ..for me any way.

If you want to test the moxie of a speaker try Kiss My Axe by Al DiMiola.  It has some tracks with big ass kettle drums that sound like explosions...talk about moving air Oh yeah, you will see how fast your speakers really are

That's why I like large planars like Tympanis -- they're the closest I've heard to combining planar realism with dynamic slam and extension. A sub can fill out the bottom octave, where few if any planars can go. For jazz or the occasional classical piece that needs more than 115 dB peaks, you can find planars that will play as loud as you please, e.g., the big Wisdoms or something made with sound reinforcement planar drivers, but not in the bass.

But of course the best choice is going to depend on your listening habits and preferences. A friend of mine has a pair of Acoustats for normal listening and Voice of the Theaters for parties. Now that's what I call covering all bases!

Two questions that come to mind are:

- Is the bass contiguous? It's hard to mate dynamic woofers with planars, particularly at higher crossover frequencies and when the radiation patterns are different

- Does the woofer sacrifice OB planar transparency and relative freedom from room modes to achieve greater heft and extension?

Yes...Big speaker...big sound.

Yes having more than 1 can be good..they are not swiss army knives !!

 VG suggestion Jim. That piece will shake the house for sure.  For future discussions about the GTAW speakers I will post on the manf. circle.

Move your head 6 inches away from the sweet spot and your planars now sound like Bose!

I think you're talking about stats ... not Maggies. 

In my last room (27 x 17), my "sweet spot" was 6' wide - so moving one's head 6" to each side had zero effect.
