I'm not really sure why they didn't arrive, but Jeremy took care of me.
So I hooked them up and got to listen to them for about 20 minutes before I had to head out for work. My initial impression was bad, very bad in fact. They sounded no better than the polks they replaced.
After 10 minutes a lightbulb went off in my head. I turned off audyssey, I didn't recalibrate cause I was so excited to hear them, and suddenly the 15s came to life! All of my buyers remorse went out the window. I now can't wait till the cx-10 arrives!
I now need to figure out how to go about bumping up the midbass on these things when they are set to small on my receiver.
