Up for sale is a Selah Audio TC Sounds 12" sealed sub with O Audio 500 watt Bash amp. Priced for a quick sale at $400. The sub is in great shape. Retail for Rick's last/current iteration of the sub with Hypex amp is $1495. This sub has never been driven very hard. I feel I really need ob bass for condo living. Alas single family homes in Chicago are a pipe dream and this sub just loads up the room too much. Zip is 60640 local sale only.
