SOLD SOLD SOLD

For sale is a pair of used 15” Ascendant Audio Atlas Subwoofers. These subs are used and in good working order. I used them in an IB setup off of a US Acoustics USB-4085. They are a little dusty and the foam surrounds have a few light scuffs, but no tears. Here is a little excerpt I got off the original site.

“What also sets the Atlas subwoofers apart from other drivers is their adjustability. The Qts can actually be adjusted to your enclosure and alignment preferences. It is at home in everything from tiny sealed enclosures to infinite baffle and dipole setups.

While the idea of an adjustable driver might sound complicated, it is actually rather simple to implement. The Atlas subwoofer is basically a 4 ohm driver. However, it also has a second smaller voice coil that is used to adjust the Qts. The second coil is what provides the flexibility.”

To wire the sub for a low qts setting use a jumper wire across the gold terminals
To wire the sub for a mid qts setting use a 1.5 ohm resistor across the gold terminals
To wire the sub for a high qts setting leave the gold terminals open

DO NOT POWER THE GOLD TERMINALS!!!!!

Did I mention these are XBL^2 subs.

Asking $160 shipped each. Thanks for looking.
