8 Inch Woofers

This is the little bad boy that got us thrown out of our building.  We were testing really loud one day and the computer guys four doors away claimed that it made their program crash.  (They made such a fuss that the Landlord made us move really far away from them.) This is also the one that boogied across the floor during a Grant Geissman concert at an LA record store.

Needless to say, it's loaded for bear.  But we'll stay away from getting highly technical trying to explain how it does what it does.   Dan Fisher said, "it defies the laws of Physics."  The Landlord said. "its gotta go".  So let's just say that if you want to serve your ears, and preserve your back at the same time, this is the one for you.  You'll get totally realistic sounding instruments, from Bass to Finger Bells, and high enough sound levels to get a lot of attention.

Two versions to pick from...

This model is available as a combo amplifier, or as an Active PA system. The drawings are of the rear panel for each version. Just choose the one that best suits your needs
