I have for sale my favorite sub, but due to downsizing and the sale of my preamp I no longer use it. I used it with several speakers ( Focal Mini Utopias, Jse Infinite Slope 1.8s, etc.) and was able to get the blend right with everything I tried. Do a google search and read about it. Audioholics has a good review/description. I am the original owner. This is a very well made unit it weighs 97 lbs. The sound is EXCELLENT!! This is not a boomy mid level sub, I have had it since 2005 and it was $1950.00 back then, to get this quality now you would be spending $3700.00 or more. It has a 13.18 inch woofer and a 400 watt amp, so it easily fills most any room with taut and tuneful bass. I will meet a buyer within 70 miles for free for asking price, will consider farther distance with gas compensation. I prefer pickup which is of course free. It comes with stock power cord, but responds very well to cord upgrade. I do not have original box which is costing me $110.00, so please no lowball offers. Insurance is $24.00 and must be paid before shipping.
