Best center substitute to match B&W 803's


Anyone know or can recommend a sleek or in wall or modern looking center speaker that is not to big ( as in wide ) that I could match up with 803'sthat would provide good clear dialogue when watching movies? I have the htm2 and it is just too big - putting in a fireplace under my plasma and need something a lot smaller ....besides the htm2 center for whatever reason Is bassy, sounds hollow and does not provide clear dialogue...spoke to b&w and they said I have no alternatives other than the htm4 but I suppose they can't refer me to another brand...any ideas or suggestions? Thanks very much.

Thanks... I tried the phantom center but it just didn't sound right...the main listening position is off center and I think that it made more difficult for the l/r speaker setup to sort of create a center...

I am not looking for perfection as what I have now is so far from sounding right...but good dialogue would be awesome ..

I will look into the Galla strada and ref a.v. Thanks!
I just realized I made a mistake - I am looking for something that is not too high...it can be long ...or wide....
