I don't want to hijack the "If cost wasn't an issue" thread so I thought I would start a short separate one. That way if someone gets the urge to drop 6 to 7 zeros on a pair of speakers and amplifiers I have just the thing. Sadly I can't build it without a 10% non-refundable retainer to cover the staff to cover for me while I make them.
Electrostatic panels that start on the floor and rise up 9 feet.
Each panel is made up a many horizontal trapezoids to keep it from having a resonance. Additionally each panel is twisted about 1% or so to again make it impossible for standing waves to develop.
The corner of each panel is set with a string that is connected to a steel ball in the listening position. A ball that is later removed after calibration. That means that all four corners of each panel are exactly equidistant to your ear, which incidentally is what causes the panels to twist. It's a Zen thing.
The array will be anchored to a 6 x 16 beam of solid hardwood on each side driven by GM100 tubes. It will be a head vice speaker where 100% of the energy of each full panel will reach the ears. A typical electrostatic speaker is 99% reflected energy from the room with the only part the panel you hear being the same dimensions as your head. This would be 70 or 80 times that. One watt would be so loud it would crack the earth.
You could hear a flea fart inside a car driving by on the highway outside the recording studio 50 yards from the building and tell the car had one tire out of balance.
So here are a few sketches of what that would look like.
