HTIB speaker gauge

post #1 of 5
Thread Starter 
Whats the standard gauge wire on these HTIB's? I would like to upgrade an old set to a new one with HDMI inputs. I have the opportunity to run new wire under the floor. What gauge could I use ? thanks in advance.

I would just go ahead and run 12 gauge CL2/CL3 wire while you have the access. Most of the HTiB use 18 gauge wire but that can vary depending on the price of the system. I've seen some that actually use 12 gauge zip cord. As long as the end of the wire will fit in the clip terminal you will be fine. A lot of HTiBs, mainly Sony and Panasonic, have their own proprietary cables with plastic ends on them that plug into matching terminals on the receiver. I'd take a close look at the back of any system you plan on getting and make sure you can terminate at least bare wire if not banana plugs. Look for a description/feature like " 5-way binding post " in the literature.

Most of the Onkyo HTiB have these 5-way binding posts, so any shielded wire you buy ( like CL2/CL3 ) will fit in the hole at the base of the post OR you can terminate with banana plugs for a cleaner look.

I used 16AWG, shielded, 2-wire, ribbed for a maximum run of 30' with no loss of audio fidelity. The advice above about checking out the terminal ends of the receiver (and speakers) before you make your run is a good idea. You don't want to run wire only to find that you need proprietary connectors. 5-way binding post is the best because it can take bare wire or banana plugs as mentioned.

I was told the gauge should be based more on the length then anything.
Is this true??
I was told to use 14 for my runs to the back, which are 20-40 feet and the front i could use 14 too or go smaller (16-18)
tia for any tips

The length of wire used is dependent on the ohm rating you are pushing to the speakers. There is an excellent tutorial on speaker wire etc but I can't find the link right now. You might be able to find it by asking up in the speaker forum. What I do remember, and what I used, is that 16AWG can be used for up to about 40' if you are running 8 ohms to the speakers. 6 ohms is a shorter length. The link has a chart listing ohm ratings, length, and the proper gauge plus a lot of other useful info. I'll see if I can find the link and post it if you can't find it.
