I'm confirming the delivery of a WorxAudio TL.118SS. (tuning ~24Hz) If that falls thru I will have a similar pro audio subwoofer prototype that uses the same driver. Honestly, i hope there is some good competition, this thing is a beast. I'll front shipping, i just need a trusty caretaker on the other end. I would like to see this run off the I-T8k!
