Hey guys I'd like to get your opinions here. Now before I start, this is not one of those which sub should I get threads or anything like that. What I want to know is the distinction sound that each subwoofer puts out. I use to own a 20-39PCi and loved it but I wanted more power. Now I've done a little research and found that the difference between the PCi and PC-Plus is pretty big. Now my question is, is the sound from a PC-Plus compared to an Ultra that big a of differnce to make it worth the purchase over a PC-Ultra? I've heard a PC-Plus and I do agree it does sound better than an PCi. So that I'm certain. I see both PC+ and Ultra have the same 525 watt Bash amp so the SPL would be about the same. So now it comes down to the driver itself, the TV-12 and dB-12. Does the sound from the TV-12 that much better to make it worth spending the extra cash? For me it would be $367 extra. I've heard that the TV-12 has its own sound which people love, but is it that much of an improvement? I plan to place my order next month and I don't mind spending the money if I feel it is worth it. I just want to make sure.
