This guy has the right idea.  He went slightly overboard but I do commend his enthusiasm.  Im crazy into subs.  They are what makes the music/movie fun and impactful.  You can never have too refined of a subwoofer system.  In my experience 4 sub drivers located in four separate locations is the minimum required in a room to get solid response approaching uniformity across the space and approaching flat across the entire bass frequency spectrum.  More is better.  However, this dude might have taken my principles a little far.  I prefer more of a balanced, musically accurate approach to levels and spl.  Looks fun though.

Over the last 30 years I have incorporated single driver subs, dual driver subs, passive radiators, ported subs, sealed subs, servo subs, open baffle subs and used dsp to try to blend them into my various systems over the years.  NOTHING made my system sound as smooth, uniform and balanced until I incorporated multiple subs in multiple locations.  Game changer.

I discovered you can have too much bass. My home theater is 326 sq ft. and I used 2 REL Reference subs for a month before I sold one, which was always the plan. One sub was a new REL G1 MkII, the other was my older REL G2 Gibraltar. I had substantial bass to 15 Hz.

Sound demos usually include explosions, submarine depth charges, Godzilla stomping and roaring but nothing has sustained 15 Hz - 30 Hz bass that goes on for 15 seconds or more like Blade Runner 2049, Denis Villeneuve's masterpiece with music by Hans Zimmer. Track 1 - '2049' and track 3 - 'Flight to LAPD' will tax any home theater. Playing both tracks at theater levels scares me, I eventually have to turn it down. Everything in the house vibrates including my body. Eyeballs are filled with fluid, when that fluid starts vibrating and my vision starts getting blurry it's time to turn down the volume. A buddy came over for a demo, initially not believing my blurry vision story until it happened to him too.

For now I have settled on two cabinets up front with dual 12” servo Open Baffle subs fortified with 3 15” sealed servo subs from Ryhmik spread around the home theater.  Although my system is tuned for flat and musically balanced response, I can raise the level of the subs for movies etc to deafening levels.  Im trying to preserve my hearing long term, so I resist doing it as much as possible.

I must be living in the Vintage Circle; another time & place!
