I am planning on running new wire for the rear speakers of my Onkyo HT-SR600 HTIB (5.1) and had a few small questions I was hoping someone could help with.
The run will be relatively long to wrap around the edges of a fairly large apartment living room. I measured about 40 feet for the longer side.
What percentage added wiring do people recommend for long runs? Would 20% - i.e. an even 50 feet - suffice, to ensure I have some slack for speaker stands adjustment, bends, etc?
There will be about a 10 foot difference between the left and right rear surrounds? Should I keep the wire length the same to match resistance levels, or clip the shorter one to a more appropriate length?
The Onkyo site lists these speakers at 6 ohm nominal resistance. They are not very nice speakers, but it's an apartment and there is only so high I can raise the volume, so will 16 gauge wire suffice? That's about the max my speaker stands will handle internally, but it's pushing the Roger Russell requirements. Of course, now I am using the stock wire, which has to be 22-24 gauge, and everything sounds fine, so it might be a moot point.
I have heard that bare wire can corrode, but my speakers and receiver have spring clips, not binding posts. Should I get some pin connectors to prevent this? If so, does anyone had recommendations for modestly priced connectors that are screw-on (not crimping)? Monoprice does not seem to have any, and I haven't had much luck in other places either.
Thanks in advance!
