I've got a new Orion HCCA 15 in a custom box for sale. The speaker has been played for less than 10 minutes, the box is custom made from 1" thick MDF with 2 6" ports and was tuned to a factory spec 33Hz. This sub hit deep into the 150's during it's one and only SPL test. Factory 2 year replacement warranty on the speaker and lifetime on the box. My asking price is $500 obo for the combo.
