The F12 has plenty of output for the price..you will notice a big difference from your 50 watt sub.[/quote]
So you got the F12... Where from, how much? How is it performing for you? Does it have enough bass for you? I have one, think it's the 'bee's knee's' tons of bass, but I haven't seen many posts here from new F12 owners reporting their findings/opinions.
I gave mine a 7 hour workout Friday, had it cranked while doing yard work then enjoyed some good old rock I haven't listened to for years. It brings a whole new dimension to music that I never expected. Like I said it was cranked for a long time, amp was HOT, AVR was HOT but everything sounded great and the F12 never missed a beat. Completely happy with it! And that's not 'ignorance is bliss,' my buddy came over, hooked up a whack of stuff to his lap top and checked the output with a mic, a meter and a special cd for calibrating. He moved my F12 about 6 inches further away from the wall and said that it was optimal for my room! Can't even notice a difference as it was already away from the wall. Oh well, he's an expert, and he wasn't even upset that I didn't buy a sub from him.
