Need help with speakers to be inside a cabinet

Hi,
I've been specing out a 3.1 A/V system which will be housed inside an indented area (kind of a cabinet) which is 83" wide x 43" high, 18" deep. There is a door which covers this and I want to put the TV (51" wide) and the 3.1 system speakers inside this space. I have a 10' wide couch sitting about 10-13' away from the TV. There is a sheetrock ceiling about 10-12' high in the whole room, a brick wall 20' accross from the TV and it's a loft apartment which is 1 open room width wise. Finally, driving with a ROTEL RSX-1056.

I met with a few dealers and have so many conflicted information.

Dealer 1) Suggests Aerial acoustics 5B's + CC3B + Rel T1. Claims the aerial's fully sealed enclosure is designed for this application and does not need air space behind or on the sides to sound amazing. Alternately suggests a pair of Vienna HAYDN's + Maestro center + Rel T1 claiming the HAYDN's being front ported will stand up OK in this application.

Dealer 2) Suggests 2x a KEF REF 201/2 and do a phantom Center + prefers vellodyne Subwoffer. He feels that the center will prooject the sound too far back and is not suitable for the application. He prefers I buy better speakers (and claims these are better).

Dealer 3) wants a deposit before he tell me what he suggests. Kind of wierd but I guess I understand.

I want these in white and prefer to buy one in gloss white but I suppose can always paint them so want to focus on the speaker choice first.

I see you guys like to help out, which speaker, if any, works well with it's back and 1 side so close to a wall? If no bookshelf or free standing speaker really works well I suppose I would get a wall mounted option such as Vienna Mozart, Totem Tribe II, or B&W FMP5 unless omeone has a better suggestion?

I'm so puzzled and the more I look the more I'm puzzled! If anyone has the time to help or make me even more confused, feel free!
Thanks!
