3. Description/Condition:

Like new, Beautiful driver, maybe the nicest fit and finish I have seen in a while. Sounds just like the Audiomobile Evo 10 I sold StattonBurrell. In 1.2 @ 32Hz is as Audiophile as the name would imply, quite efficient as well. Feed it 300rms and call it a day, def a nice sounding driver and for that price you cant go wrong lol. Truly a beautiful woofer.
