Stacked Quad ESL 57

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 ;-)

Your first observation is what separates them from the Martin Logan designs. Roger West argues that a truly curved diaphragm involves compromises. While the Sound Lab design looks curved, the grid creates angled flat facets. Horizontal dispersion is most unlike other electrostatic designs. Also, unlike other 'stats (like Acoustats) they do not employ multiple panels as well. The deliberately variable height grid (to control inherent resonances) is placed over a single very large diaphragm.

Hi,

New member but this thread is perfect.Is this the best place to post this? I want to stack my DQ-10s. it will raise the sound stage on top of the other good points. I will ignore the bad ones until I listen then look into improving those issues.

Any help on the bracket would be great. !st choice would be buy a set, second would be make a set.I will power each stack by a bridged adcom 555.

I listen to mostly DVD concerts, CDs, tv(sports) and a rare movie

Thanks

Mark
