@sokogear, They are a powered recliner just like any Lazy-Boy. They are not specifically designed for theater use although I use three of them in a theater set up. There is a second row behind up on a platform. It uses a Stessless love seat. I am going to have to get creative to make a foot rest for it as there is no room for ottomans. The problem was that I could not find any theater seating that could be made with the kind of leather I wanted. Most of it is not built very well.
@donavabdear , I am agreeing entirely. The only difference is I prefer to be the one to choose the amp. I use two types of drivers, ESLs and subwoofers. Never is a long time but it is highly unlikely I will ever use anything else. Both types of driver have very specific requirements and are demanding to drive. The ESLs are very reactive being nothing but large capacitors with very low impedance at high frequencies. Then there are the subwoofer drivers that have huge magnets and 4" double layered voice coils which throw enough back EMF to light a city. Although there are some amps capable of driving both types it turns out the best amp for driving the ESLs is not good at all for subwoofers.
Another point is that the room is an essential part of the loudspeaker system. I use microphones and computer programs to measure the result and apply digital equalization to get what I want.
