Stacked Quad ESL 57

[E-Stat]

...it has limited vertical dispersion but that is limitation is common to Electrostatics

Not with seven foot tall 'stats like the SL U-1s. Not to mention the nine foot tall Majestics.

Stacked Majestics?!

Impressive wall...

A Apogee buddy of ours in Jamaica runs tripple Stacked Quads and used to repair them. He did say that the standard versions of the Quads are simple very limited. He replaced the foils (1/4th the thickness), stronger magnets, different frames, tripple stacked and driven by handbuild SilverKing amps (purely silver [incl. circuit traces])....spposed to be freaking good. But in the end, its not a Quad anymore ;-)

PS: On a side note, if you stack two speakers you do not get twice the bass, clarity, or dynamics ;-)

Not twice the dynamics (10 db), but you do typically pick up 6 db. And some low end extension.

While I agree that increasing sensitivity doesn't improve clarity per se, it does allow me to run my Threshold Stasis at reduced power levels in pure class A with my double New Advents. It is smoother that way.

Also, since they are stacked they create a linesource (tripple) and you get less drop off over the distance. By the way, did you ever measure your U's inroom responce?

No. A good bit lower, however, than the Acoustat's they replaced. They are back home in Utah now getting repaired after the clowns who shipped them skewered them with a fork lift. One of the crates was destroyed.

They worked ok for a while, but developed problems. At least, I didn't have to ship the entire 900 lb package back. The frames alone weigh 200 lbs. In April, I'm flying to Chicago to attend a meeting where I'll meet Dr. West and hear a pair of the new Majestics.

I think i remember seeing the picture of the shipping crate. Did you post them in the AudioAsylum?

The Apogee's are just as bad for shipping, and very critical. We had to remove the fence and get it through the window. How did you get your Soundlabs into the room? The reason i ask about the measurements is because i mesured the Maggie 3.6, Apogee Scinitlla, DIVA and the VMPS speakers and found that the Panel speakers have a almost flat responce (+-2db) exept in the bass where they have a huge output. Apogees are designed with the backwave in mind so thats easy to manage. The 3.6 has limited deep bass output but is quite weavy and with the help of a EQ can sound a lot better.

Your Soundlanbs are quite interesting, and the panel is not curved but you have a multi driver array, so i am curious how this affects the room. Maybe some day you will measure them ;-)
