Danny,
While I really like my pair of OB subs (which use two SW-12-16FR Servo Sub Woofers per enclosure), for HT I need a little more impact and WOW! factor than they can provide.
I currently have a pair of homemade subs that each have a 2.8 cu ft internal volume and use a single 12" B&C driver. The cabinet has a slot loaded port underneath, which I am told is tuned to 19Hz and increases the internal volume to 3.0 cu ft.
Is it possible to take out the B&C driver and replace it with SW-12-04 Servo Sub Woofer?
While the cabinets are nothing to look at it, they are well built and I would really prefer to not have to make new cabinets.
Thanks,
George
