Eh hem!...Subwoofers... What do ya know?

WOW!

What a bunch of total bass freaks!

My magnepan 3.6’s drop off at 30 Hz and sound great.

Bass quality has a lot to do about power amp quality. You can not be a cheapskate.

How much musical info is below 30 anyway?

To hear sound below 30 you need way too much volume. That would disturb my neighbors below.

And the peaks, valleys, and echo slap are too much to deal with.

Multiple (4 or 5) subwoofers ruin the bass sounstage.

have you exhaustively set up , tweeked then disliked 4 subwoofers ? It makes your sound stage that much bigger. The beauty part is that you dont make your bass any louder. each device runs a bit lower . And if set up properly , puts the bass focused where you want it. If there was content would you not want to hear it ? Especially considering its at the portion of the audible spectrum that doesnt require bat ears . Your sound stage is freed of the mud that is made with poorly set up system .  

That would for sure get you kicked out of an apartment . Way overpriced for what it is , an electric motor , a woofer motor and a fan. A proper price point would be 800 bucks not 13,000 . Very curious though.  

I’ve always been able to hear where they are . And thats not good .

Then they are running higher than 80Hz.

This is entirely incorrect. There is no 'bass soundstate' at less than 80Hz; below that frequency bass is perceived as omnidirectional. It is the harmonics of the bass instruments that gives you the soundstage. In the meantime, multiple subs get rid of the 'peaks, valleys and echo slap' since bass 'echo slap' is what causes standing waves in any room.
