<font color='#000000'>Hi. In setting up a home theater (7.1 using Sony STR-DA7ES which is rated 120 watts x 7 channels), in a large 31’ x 16’ x peaked ceiling 14’ tall at its highest I’d like to use a pair of Klipsch RF-7 towers as the main stereo front speakers, a REL Storm III subwoofer, and Gallo’s for all the rest. I’d use a Gallo Nucleus Due for front center as well as both rear channels (the ones used by 5.1), and Gallo Nucleus Micro’s for the remaining 2 Surround-Back speakers (used by 7.1). Klipsch of course makes companion center and surround speakers to match the RF-7 (RC-7, RS-7) but I’d rather use Gallo's for the size factor. Cost would be about the same.
Is there anything dangerous, or at least worrisome about doing this (mismatching across these 2 brands in this way) from a technical point of view? And will 5.1 or 6.1 or 7.1 when it gets here sound natural and balanced do you think, or will voices change in pitch as the character moves around from Klipsch’s to Gallo’s and back? The room being so large, and the rich high end I hear in the Klipsch’s make me want them for the mains, but I’d really rather go with Gallo’s for the rest. The Due in center front position would mount just under the “picture on the wall” 3.5” thick 42” Panasonic plasma TV and it’s much easier to properly position the other Gallo’s on the side and back walls – they don’t stick out 9.5” plus space for the rear ports, and are less conspicuous (in white) on the white walls. Can be mounted at proper height whereas windows prevent puting the RS-7's anywhere but 9' off the floor on the rear of the side walls.
The RF-7’s are 8 ohms, are rated 250 watts maximum continuous, have freq response of 32Hz-20kHz +/- 3 dB and a sensitivity of 102dB@1watt/1meter (in case that helps to answer the question).
Believe the Gallo's are able to stand up to 100 watts, but let's assume I won't push the Sony higher than that (since the cost of a divorce would push this little project out of my budget).
One other question: my computer workstation where I spend 40-50 hours a week minimum is in a little alcove in the front corner of the room. So from there the mains are a little behind me and point away. The Sony has a switch for A/B speaker selection (A or B or both or off) which is normally used for mains in another room. But it occurs to me the the 2 Due's I would mount as rear speakers in the 5.1 setup are not in a bad position to act as stereo speakers (left and right mains) when I'm at the computer because they at least face me and are on the far wall. So could I simply "jumper" the speaker leads at the back of the Sony receiver (B speakers left main going to 5.1 right rear plus vice versa for the other one), then use "A" for normal use both with 5.1 and stereo, use "B" for stereo only when I want to face the music toward the computer, and promise never to use the A+B switch setting? (And what happens if somehow that did happen, just muddy music or something worse?)
Thanks.</font>
