Skinny speakers and wretched excess

I'm upgrading my HT setup by adding a plasma screen. Needless to say, my center channel speaker can no longer sit on top of the tele. I was thinking of buying a pair of speakers to flank the TV and provide center channel sound. I have watts to burn so I thought I would wire them in parallel. The question?: My shelf is 52 inches wide and the TV is 38 inches wide. That leaves me 14 inches for a pair of speakers. Can anyone give me recommendations on speakers that are 7 inches wide? Weird audiophile question, but ergonometrics are key here. My basic system:
Krell KAV1500 (surround)
Krell FPB 600 (mains)
Nova Audio Rendition (front speakers)
Bag End Infrasub-18
Pioneer Elite DV37 (source)

I'd like to spend in the 1500-2000 range used. I don't need much bass but it's got to support a lot of volume and have great accuracy in the vocal range - natch for a center channel. Thanks.
