<font color='#000000'>Hi Rob. I have Wharfedale Diamond 8.3's (rated down to 40hz).
I really don't understand why the two crossover thing is a bad idea. I mean, i've read a few places, where it's not a desirable solution. But, my ears don't hear anything bad.
I like my receiver alot, it sounds great. But, the dang bass management is terrible. I may have to swap it out. And, yes, the sub has a bypass switch. That's why I said the receiver's crossover sucked, it's too high.</font>
