Midbass recommendation...

Allright, slight change of plans! I have now sold my TSX.44 and purchased a Treo SSi12.44 12" dvc. I am going to bridge my ZX-450, one channel on each voicecoil, giving me a real world 600+ watts RMS on this wonderful 750 watt RMS subwoofer! I will also be running my new ZX-350 on my SR-6500's (Here are a few pics pre-install), throwing an honest 100+ watts RMS on each. In the long term, I may wind up dumping the ZX-350 for another ZX-450, along with adding a set of 8" mid-bass drivers in my doors. I am not sure what I will use for a mid-bass as polk doesnt make an 8" SR series woofer. Any recommendations? Maybe I would be better off buying another set of polks, selling the tweeters/crossovers while keeping the mids as dedicated mid-bass drivers? What do you guys think?

Try and find some elite 9's. It those cant fit, I would personally try to find some old Kicker R series (I think thats right) midbasses. I was really impressed by them when I heard them a few years ago. The Image dynamics CX series were nice as well.

Try one. Or Two.

Make sure that ZX450 is gain matched between channels if you're using it to run a sub. Personally I would get a ZX500 to replace it, and keep the ZX450 on components/midbass.

Kicker SSMB's are the best "bang for the buck" shallow midbass I can think of. They are quite cheap, mount easily and sound decent. Morel has some good 9" midbasses, or you could check out the Revelators that Ben posted.

I have to agree, I think dumping the ZX-350 and picking up a ZX-500 in the long run would be the way to go...

I have never added a set of mid-bass drivers, but have heard you want to use a tonally matched speaker... true? If so, would I be better off using another SR-6500 mid as a dedicated mid-bass driver?

Matching the timbre of speakers is most important when you're talking about multiples of drivers. This is very important in home theater, where you don't want to have shrill metal tweeters behind you, when you've got soft dome tweeters in front. In a case like this, you want the tone of each speaker to match, so that sounds from behind you sound the same as when they come from the front.

Since you're not adding a new multiple of a driver, you're just covering a new frequency band, timbre matching is less important here. In this case, if you want midbass I would suggest a purpose built midbass driver. Adding another polk speaker would be money better spent on acoustical treatments. Doing so would make your single component set likely sound as good as one with a separate polk midbass. If you went with a dedicated midbass, you will at least get the benefit of being able to use a lower frequency range, which lets you drop your subwoofer to only play the non-locational notes below ~60Hz or so.
