10" Quatro box *PIC*

The garage stereo needed a little help in the bass dept, so's I built up this little number to "assist". I call it the "auxwoofer". 30 liters net, 36 gross, tuned to 34 Hz by (1) 3" vent, 13 3/8" long. Design is -3 dB @ 38 Hz, -8 @ 30.

Works real good, much better than its predesesor along side.

Here's a construction shot. I thought that long tube could use a little extra support.

Have fun!

I've got two eights I impulse-purchased a while back - does anyone know if I can get some numbers?

If they are the Optimus Pro CSW series...

The problem is the box is way undersized for the Pro Series. That "Radio Shack" driver is actually an MTX 3000 10" in diguise. I infamously ran one in a 2.1ft³ vented box and it would play massively loud. Not super clean. BUT LOUD.

Looks like 'em...

Darn. Was hoping to just cut a coupla holes in a box, stuff in a piezo, and hand 'em over to the girlfriend's 11 year old punk rocker daughter...

Hehe...

It must have been a while back. I think I got mine at some "stupid good" 2/3 rds off "clearance" deal at RS back when they actually carried speaks.

Have fun!
