The House Wrecker is appropriately named for it’s professional quality bass output. Considerably more bass than is recommended for most homes, it’s popular application is DJ use, nightclubs and professional sound re-enforcement. Of course there are those who enjoy fixing cracked plaster and insist on using one in the house and even some who have crammed one into their vehicles... go figure!

THE HOUSE WRECKER model HWK-15
|This is the box that moved enough air through the bottom ports alone... to levitate a 3x5' rug off the floor!
Usually applications that need this much bass will go with folded horns, but horns can create standing waves so large that much of the bass is canceled throughout the center of the space - right where you need it most! The HWK has far less loading problems in a given room and unlike a horn, can be used in smaller spaces.
In large spaces you can achieve seriously low bass - often below 20Hz.
It is also possible to scale this box design up or down for use with 12 or 18 inch subs.
Create a 7th order dual compound isobaric sledgehammer with 4 drivers!
PERFORMANCE - meaning usable clean output is possible as high as 200
Hz! For small clubs, when a good chest hit is desired, we use a
single Peavey Black Widow and get a rock hard hit between 40Hz and
wherever we cross it over to. When low bass is desired a
single 15 inch subwoofer is all that’s required.
CONFIGURABLE - With the ability to use between 1 and 4 drivers, it is possible to achieve up to 14 different tunings of this cabinet without touching the port sizes. This is a guarantee that you will have bass with a wide variety of 15 inch bass drivers.
•This box is offered for hobbyists who love to experiment. Since there are so many ways to load it, you should be able to find at least one that works with your woofer - regardless of the driver specs. (Theil&Small)
•The above illustrations depict only a few of the many ways this enclosure can be loaded. You may also experiment with running one of the woofers as a passive radiator for increased gain. (Higher Q)
•The ideal woofer selection if you going for low bass would be a sub-woofer with an fs around 20 Hz, and a Qts less than .38 and a minimum VAS of 10 cubic feet.
•The box can be scaled down for 12 inch woofers or scaled up for 18 inch woofers.
