Ive been checking used sites off and on and finally nabbed a pair of 18" IB13 FI subwoofer drivers for $295 a pair (local pick up-how lucky??)
... now to find an XTI2000 amplifier... badass sub for like $550?? cant beat it!
I think your MONSTER sub would be better, and look like furniture to boot... but thats neither here nor there

Is it me, or does the box have 3 different size drivers? What kind of configuration is that?
That was a box built with a design similar to a VMPS Larger sub using higher excursion TC Sounds LMSR drivers.
The Larger used a active 15 & 18" driver with a 18" passive on the floor that acts like a port.
Here is the sub it was eventually going to look like...

Interesting. According to convention, the passive should have at least 1.5x the pistonic volume capacity of the active driver. But in that box, there are 2 active drivers, one being the same size of the passive, which would suggest that the passive could potentially be pushed past it's x-max. I would have thought that only the 15 would have been active...

Yup... but only Trey, Tom and Russ know how it sounded as they all heard it before it was sold off for parts...
From my understanding it was bucking Russ off it and thrashing around the floor like a bucking bull with only 1k of wattage from a Pro amp lol....

So I did a "bass walk" and the location I plan to put the hole is the left front corner of the room in the floor. I think this will provide the best bass response.

Waaaaahhhhhhh.....in the floor?! :a

Is the listening position still almost directly in front of the front door, about 4-5' out from the door?

In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.
The best way to enjoy digital music reproduction is to never listen to good analogue reproduction.
If I find another pair of fi drivers used, i could see adding another pair in the future
All the bass!!!!! I want ALL THE BASS!!!!!

2 IB drivers will only equal 1 single box driver. I think that you will be underwhelmed unless you have heard one before. The bass is cleaner, smoother, and deeper but will lack impact and the heft/mass that a huge box sub delivers. You will reach Xmax with very little power applied and thus headroom will suffer. I would make the manifold to accept another pair easily or plan for a second one in the other corner.

The end result will be what it is. Infinite baffle versus Direct servo.
Who will win?
Let your ears decide....

You are going to love an IB. Have heard several. Not sure why, but have seemed to integrate and call less attention to themselves with music yet call plenty of attention to themselves with movies

I am simply blown away what two of these freaking woofers can do. I thought I needed more and actually acquired 6 of them but I am just going to do 4, two per side of the room
The quality and extension of the bass is absolutely stupid

Holy cow!!! That looks awesome! How's the ceiling deal with the piston motion of the air slug in the box?

What I am really hoping for is the low end extension and a little bit of reinforcement above 30hz. My room is also not tooooo huge, 22'x16'x8'
