Looking for some expert Advice on a possible speaker configuration for my HT.

I currently have a 5.1 system running the following speakers on an Integra DTR-50.2 receiver:

B&W CWM800 - Front Mains (2-way in-wall speaker system)

Description: 2-way in-wall speaker system

Drive units: 1x ø25mm (1 in) aluminium dome tweeter

I am considering moving it to a 7.1 system using some Boston Acoustic speakers I have had for many years. The BA's have been in storage now for about 5.5 years and I really cannot recall details on their sound in comparison to the B&W's - all I remember is at the time they seemed decent. My big question is - would mixing in the BA's with the B&W's be a bad idea? Would I end up with a decent sounding 7.1 HT system or would I be better off leaving the system as a 5.1 and keeping the BA's in storage?

Below are the specs on the BA speakers that could be added to the system:

Boston Acoustics Lynnfield VR960 - Possible Mains?

Frequency Response: (+/-3db) 29-20,000HZ

Sensitivity [1 watt (2.83V) @ 1] 90db

Built-in Subwoofer Amp: Power 75 watts RMS

Bass Unit: 8" (200mm)

Midrange: 4 1/2" (115mm)

Tweeter: 1" (25mm) anodized aluminum

Boston Acoustics VRS Micro Di-Pole - Possible 7.1 Rears?

Frequency Response: (±3dB) 120-20,000Hz

Sensitivity: [1 watt (2.83v) at 1m] 86dB

Full-Range Driver: 31⁄2" (89mm) copolymer

High-Frequency Driver: 21⁄2" (65mm) polymer-treated paper

Crossover Frequency: 350Hz

Any thoughts or advice on this setup from you AVS forum professionals would be greatly appreciated!

Don't mix the front left, right and center speakers - they need to be

voiced matched. You can use a different brand for surrounds. If you

do not have a Boston center - then use B&W for the fronts.

Don't be afraid to use anything g that sounds good to you. As long as the speakers and amp don't over/under power eachother, you should be good to go. The most important feature for any speaker is accuracy, but each person has their own taste as to the timber. Good luck!
