28H X 24W X 27D AV15 sub for sale. This sub is front firing along with two heavily flared 4" ports under the black grill. The sub has been stained black with Solar-Lux B503 over the oak veneer and then semi gloss Clearthane applied for a top-coat. This sub is passive and is tuned close to 20.7 Hz. The driver was rebuilt by TC Sounds for it was possibly faulty when I received it. It works great now and I have pretty much always ran it in a dual or a three sub situation so it has not been abused. The inside of the grill has some carpet tape holding the fabric in place to assist in the glue drying time. I think this could be removed now but is not noticeable with the grill on. It is on the back edge of the grill itself. Briane Bunge of (Rutledge Audio) was the builder. I have the original box and this sub is to large to ship UPS so a terminal to terminal shipping arrangement would need to be made by me if you are close to a city or large town. I run a couple of SVS 25-31cs+'s also and have just decided to go with three 25-31+'s for it is to hard to fit all three subs in the same corner. (WAF) The AV15 does very well on it's own though. Major SPL in the lower regions. It blends very well. I payed $650 for this sub about six months ago and I would be willing to sell it for $400 Pics are on page two.
