Well, chatted with someone from PSA, may have been Tom, didn't ask for a name.
I have been convinced to go ported and go through v1500 route as the output will be so much more than the f12 I had down low. It won't dig as deep (around 7hz) but that shouldn't matter anyway as long as it shakes me, the couch, and the foundation haha.
If it does not, than I don't know where to turn. V1800? V3600i? DIY with SI HST18S
The v1500 is free shipping both ways so its the safest option. Not taking anything away from its quality, it's just going to hurt to send the 66lb rythmik back on my dime.
