Well, the SPL is the same whether you put 4 subs in one 300L box, or 4 have subs, one driver each in four 75L boxes (assuming good acoustic coupling).
It also takes more time to build, move and setup 4 subs.

Seriously, I have no life.
Who said anything about me having a system like the one I described? FWIW, I don't. I listen about 10dB below reference in my great room. However, I do plan to put something you would definitely consider excessive in my basement HT that I'm getting ready to start construction on. ;)
I did car audio for over 20 years- I don't think I'll consider it completely excessive. I also had a pair of EV 30W woofers in a fairly small room and didn't think that was excessive, at all. It was actually very well balanced and Holy Crap!, it went lower than anything I have heard, effortlessly. It wasn't like a rap system, it just hit every frequency. I only wish I could have brought them into this house.

I could feel the helicopters from 'The Wall' outside while I stood outside.

If anything, having this number of subs and being able to reach those frequencies is great but I'm not sure how much software contains info in the sub-20Hz range unless it's a test disc, caused by distortion or special effects. For a studio to put information in that range without stating it is irresponsible, at best. A system that can't reproduce these frequencies to the point of audibility wastes every bit of power demanded of it and can damage the speakers in the process- it's no different from playing a warped record without a subsonic filter and I don't know of anyone who would want to do that on a system that could actually reproduce it. This also means that, because they would be catering to less than 1% of the audio market, there's no reason to put anything there. I'm also pretty sure that there's less than a handful of recording studios that can reproduce these notes and if they can, they're not using this ability because most master for smaller speakers.

If you have other people living in the house, I would honestly consider completely separating the music/theater room from the rest of the house. I would also isolate the room from the foundation. This would also be the perfect opportunity to use non-parallel walls, in order to minimize standing waves.

I hope you are narrowly discussing music software.
There is A LOT of content below 20Hz in movies.
See the thread for many many many waterfall charts of audio content in movies. You will see content down to 5Hz.
Here is one from The Hurt Locker with serious content down to 2 hz!.

This is mainly a Home Theater Forum. While discussing these new drivers from TC Sounds people are mainly discussing their use as drivers in subwoofers for home theaters.

I am so tired of reading posts on the interwebs of people who pretend/think they know what they are talking about.

This forum is here to help people learn. If there is something you do not know just ask questions. Don't make statements that are simply uninformed.

It is not irresponsible to put content this low. Every well designed system should have a filter protecting the sub/speakers from reaching damaging limits. If it does not it is not well designed.
