I was watching an episode of B5 tonight, "Severed Dreams" from the 3rd season DVDs that my brother gave me for Christmas, and I was pondering that while the audio is pretty clean, and thankfully free of the gosh-awful 100 Hz boom that seems to be recorded onto almost all audio-video material, these days, the audio track is in fact missing just about all the info. under about 100 Hz or so. That's pretty disappointing, on a DVD!
I even took the grill off one of the speakers to see if maybe there was some really low stuff, under the tuning frequency of the woofer cabinets, that I was therefor missing. But, no... no flutter or even significant cone excursion, even at pretty high levels, all the way through. Gee... you'd think that the destruction of a couple of Earth-Force destroyers, among other things, would generate at least SOME low frequency vibes.
I ought to put the audio track through a real time analyzer, but, the above tells me what I need to know. Contrast that to, say, standing near the engines of a freight train, starting to pull a string of 80 fully loaded coal hoppers from a dead stop. THAT's vibration. The space shuttle ride at NASA is even more fun - but that's getting beyond the capability of even exceptional subwoofer systems. Still... no bass below 100 Hz???

Now, I'll grant you that I have never been on a large vessel being blown up or rammed (perhaps the water damps out some of the vibration?) But, you can't tell me that two immense spacecraft colliding (the Churchill ramming the Roanoke) isn't something that those on board both would not feel all the way to their tailbones! Either make a real effort to at least somewhat simulate that, or, assume you are not on board, and then of course not hearing / feeling anything through the vacuum of space -- but who does that on TV or in the movies? That's no fun at all!
Possibly, for the TV show, it was assumed that powerful low end would not work so well on the typical cheapy speakers in TV's. But, why not "get it right" for the DVD's?
Star Trek DID "get it right" (at least on the Telarc CDs of the audio). I used to sync the VHS tape of "The Klingon Battle" with my CD of such. And, that CD on an exceptional home system or a really good clean car system is just freakin' awesome: You REALLY
feel like you are
ON that Klingon Battle Cruiser...
I think one of these days I'll bring in the DBX Subharmonic Synthesizer I picked up some time ago, and try it out on our system in the living room. That might add some fun to B5!
