Totally happy with mine, have had it about a month now. Step up from a 10 inch BIC, night and day difference in sound quality from the whole system (Yamaha RX-V663 AVR) when balanced with this new sub. It makes things sound, well, articulate - as Rythmik says. It's true. I compared the same subs as the OP, including the EX as well and just felt the LV12R would be the best bang for the buck - and I could not be happier with the result. I just love it.
