Default (1) 15" sub (2) 15" PR's 18.7 hz build

This is a sub i designed n built. I used a re-built 15" RE SE sub with two maelstrom 15" passive radiators. Tuned the box to 18.7 hz and modified a Bash 500 with resistors to turn the stock 30hz high pass filter to +4 db at 18.7hz.

Really nice construction!

I use a isobarik 15" with Maelstrom PR myself--wanna trade? You sub is what I would really like but my wife would kick my butt out of the house. The sheer size, depth and weight of the monster should take care of any rocking issues from the front panel.

What main speakers do you match it with?

Thats a major feat of engineering, all those strengthening batons.
I wish I had that much patience. My boxes are very simple 20mm plywood with 2by2 inch bracing.

Thank you. And yes cause of the weight and spikes i think also id dosnt shake or viberate at all. I did a test run before braces curious of sound changes without then with bracing and it made a huge difference. Right now for mains im using Alesis monitor 2's three ways. But im looking on building some mains. Just cant figure out what. I want floor standing. Maybe statements i duno. Any suggestions??
