Yeah, every small speaker has huge bass that defies their size lol.
I'm not saying driver size is the only factor. But when you essentially double the driver size and add a midrange compared to a speaker that's already overpowering a room, common sense will tell you it just won't work. I had a huge peak in bass response in that room. It wasn't the speakers I had -PSB Image T55, as I compared their frequency response chart against what I had using a Rives CD and Rat Shack meter. No matter what I did, I couldn't flatten out the bass in that room. The T55s weren't the most bass heavy speaker out there. The F12s are significantly fuller sounding , as I've heard them side by side in a good room.
I really like the F12. If I had a room big enough that they could breathe properly, they'd be very high on my list. My current room won't let that happen (different room than the above described room, but not much bigger in terms of space). I've heard the F12 do well in a medium sized room.
I know this is side tracking the thread. Sorry!
