Well for one no one has heard this system but will say it's "too much." Great high end stereos are always "too much".
Also you'd recognize the difficulty in accurately reproducing very deep tight bass and huge dynamic swings. This is difficult enough in music let alone for explosions and things like that. Play the 1812 Oveture on a system and see how quickly it makes a b1tch out of a system trying to recreate it.
"Too much bass, too much wattage". You can't have too many watts. For one you only turn it up as loud as needed so if you have 2000W but only use 200W that's not going to be "too much." There is also something called "headroom" which is basically the ability to have large dynamic swings without overly stressing the system. It can take enormous amounts of power in short bursts to recreate powerful sound effects.
More speakers is also useful because distortion is reduced and headroom is increased. If you have two speakers instead of one with the same power, each speaker will move half as much to produce the same SPL level. This means less distortion, especially the case with high volumes and power hungry sound effects that can really stress speakers. You don't want a single woofer moving like crazy for best sound...you want more moving less.
I've seen system and heard systems that you would THINK would sound bad but sounded great. You can't always just judge by looking at it. I've seen planar setups in bare rooms that technically speaking ought to sound awful but sound great.
Now if you want to talk about microphonics with the tube amps with such high SPLs, sure. If you want to talk about how acoustically that room appears to be quite inadequate--it almost looks totally ignored as a factor.
