Surround sound wiring

post #1 of 3
Thread Starter 
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.

My questions:
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!

You should be alright with 16 gauge.

How did you measure the 40 foot length?

I wouldn't worry about corrosion on the bare wire with spring clips. Not worth buying pins unless you just want it to look cool or be easier to disconnect and reconnect later. They shouldn't corrode in a normal environment, and if they do just clip a bit off every year or two and restrip the wire.

I measured the base of the room from the approximate location of the receiver (I'm moving it soon) to the approximate location of the stand, then added about 7 feet for the run down from the receiver and up through the stand.

Thanks for the quick reply!
