Center Channel needs to handle bass?

I don't think the center has to handle serious bass. It is mainly for diologue. The bass from car crashes or explosions should be routed, via the processor, to the subwoofer. Bass doesn't give directional clues, so you shouldn't be able to tell it's coming from the sub and not the center. I hope this helps.

It's too bad you can't audition, because opinions vary on this. IMO, the center channel doesn't need to handle the same kind of bass that your fronts do (if your fronts are your mains for 2-channel), but it has to be a pretty good speaker. Over 75% of most DD and DTS soundtracks come out of the center. Also, I like to set the crossover pretty low, even with movies, because I like a sense of direction (which you CAN and DO get with mid-bass), especially with the rears. IMO, your rear speakers don't have to be great-sounding speakers, but these have to put out OK bass (I use Energy C6's, with 6-inch bass-drivers). My center channel speaker is from the same company as my fronts (Snell), though not the same line. It has dual 6-inch drivers. There are other ways to go, though. If you have more than one sub, you can use them in stereo and that helps, or put one in the back. Anyway, I'm rambling. My main point is that this depends on personal taste. In my view, you need a good center channel speaker, and both the center and rears have to be able to spit out OK bass (down to 50hz or so), if you're just using one sub (as I am). To my ears it's just for the really low frequencies that I have a hard time telling where it's coming from, so for the frequencies above that I want them coming from the right source. Good luck.

If your HT processor sends a full-range signal to all speakers, your center channel may handle some lower frequencies, but the really deep stuff gets sent as a LFE signal to the subwoofer. I doubt that your center channel will see much information below about 60 Hz.

I have Vandy 3A Signatures as my main speakers, and a Vandy VCC-1 Signature center channel. I personally like the Vandy center channel, although a friend of mine had one and sold it, saying it sounded closed-in to him. If you decide to look at the Vandy center channel, I personally do NOT recommend spending the extra money for the Signature model. The regular VCC-1 is a good buy used (usually $300-350 used), but I don't think the Signature version is worth the extra money.
