Somebody estimated 277 Liters. You get an A. We figure the active volume is around 270 l. As with all Japan intended systems, the low end is deliberately lean. The published curve is an anechoic curve which is very hard to interpret with regard to real in-room response. The system has 3 dB more output at 30 Hz than a S9800. It has the tightest and best defined bass reproduction of any JBL, ever. It is not as fast as the 100 dB woofers, but goes much deeper. In multi-channel, the use of a sub is normal and will take care of the issue. In 2-channel, some EQ could easily be used as the woofers have tremendous headroom. We have already sold 4 sets of 3 Everest for front (RCL) channel use in a multi-channel setup. 2 sets in Japan and 2 sets in Europe. We have over 300 systems on order for delivery by the end of this year. It will be a world wide product, but the majority of the sales will be in Japan. The US will be the least as the general clientele here want cheap and small. We would love to build real product for the US, but there aren't enough people who would actually buy high end product to make it a money making venture. We do, however, offer really fine product through our Systhesis dealers. The Everest is no exception. We have a package system of 3 Everest, 4 18" subs and 8 SK2-1000's plus some really nice electronics for a cool $250k.
A note to Mr. "I hate electrolytics". The ones used in the Everest are there for a reason and you can replace them with "gold plated audiophile parts of the day" and the sound won't improve one bit.
A comment regarding the 2441, 375 or any other JBL compression driver. The 476Be is better in every way! It measures better in response, harmonic distortion and decay properties - period. More importantly, it just plain sounds better by a huge margin, unless you like hash, grit and false dynamics due to diaphragm breakup. We will be glad to sell you one for a cool $3500. Unfortunately, the extremely low volume and high labor content make the driver really expensive. The fact that we pay $530 for each raw Be diaphragm doesn't help much either.
One last thing, JBL will be at the CES in January playing the Everest. We will be in a Hilton suite. You are welcome to look us up. We tried to get in the Venetian with the other high end companies, but we were unable to get a room with decent size parameters. So come to thhe Hilton and I will personally show you the difference between Hi-Fi and real music. (The Gods permitting and the room not being too weird)
