I am new to HT, and getting system setup. Fun stuff! I know very basics of gauge and run length, nominal impedance of speaker, etc. Now...

My home already has 18 gauge wire (Belden 8760 CL2 rated) running right where I want the surrounds (5.1) to go on wall. The runs, though, I estimate to be 35 feet or so. It bugs me a little, well, more than a little, that I really need a larger gauge, but here is what I would contend with...

1. Theater area is in basement, with no immediate access to space above drywall ceiling. Area is finished area.
2. Joists run perpendicular to the run
3. Suspect cables were ran during construction, so possible they are stapled to joists. I pulled on them and did not give after a foot or so allowance out of the wall.

I will be running Klipsch RB-51 ii speakers (8 ohms) with Outlaw 7125 (125wpc, 8 ohms) as the surrounds. They, of course, will be set to 'small' during setup of processor.

So, worth the trouble to try and run larger gauge in, or call it good as is?? Thoughts, suggestions? I know electrician with entire van of tools and has the know how to get it done if highly recommended, but I imagine not something he wants to contend with, nor do I, if tradeoff is minimal.

Thanks for any input.

OK, thanks. Not sure why they ran 18 gauge everywhere. Yes, the RB-51 from Klipsch is rated at 92 db sensitivity. Any other input welcome.

Good, another vote in the 'right' direction. I could probably go with RB-61s, which would give me another db of sensitivity to 93. Got some Blue Jeans 12 gauge picked out for fronts and center!

This is good news guys, thanks. Given the same conditions, at what length of run would you say, 'Yes, going to 16 or 14 is a must!'?For example, instead of 35 feet, the run was 50 feet, 60 feet, etc.

Good deal then. Wanted an idea of a margin of error for my guesstimated 35'. Hopefully get the whole ball of wax up and running sometime this year. Thanks again!
