Well, many of you have followed my original build up of my first test enclosure, and after playing around with it, decided that a down firing design was out, since my floor flexed almost a half an inch from the sub, so my next design here has been refined towards my tastes a bit better.
I originally had an 8.3 cubic foot down firing slot loaded box tuned to 20 hertz. I just wasn't using anything that low, so I re tuned the first design to 28 hertz, and liked it so much, I got a second driver, and built this enclosure.
It is a separate chamber dual driver box, at 6.7 cubes per driver, each with a 4"x12"x22" port tuned to 26 hertz. It is running 1000 watts RMS to the pair, and hits so hard at 18 hertz it flexes my windows about a half an inch. I am almost scared to turn it up all the way because it feels like it is going to cause some serious damage to my house or me. I tuned it fairly low, for sound quality, as two 18" drivers are SPL monsters anyway.
They definitely need more power, and I am looking at getting a new amp to power them soon.
The original box has been sold to friend for his Atomic APX18. A 30kw burp monster!

Just thought everyone here would get a kick out of it. Enjoy! Bash it, rate it, comment, let me know what you think.
