Hi!

I had my house 'prewired' and wasn't all that happy with the quality of work. The speaker wire that's used in the wall is printed as...

Honeywell 16 AWG 2/C (ETL) 3038038 TYPE CM-CL2

I did a search and found this....

Construction:
Conductor 16 AWG 26/30 Stranded Bare Copper
Insulation Polypropylene
Insulation Thickness 0.006" nom.
Insulation Colors Blk,Red
Insulation Diameter 0.070" nom.
Lay Length 2.5" nom.
Jacket PVC
Jacket Thickness 0.015" nom.
Outside Diameter 0.172" nom.

Properties
Temperature Rating -20 to 60 oC
Operating Voltage 300 Volts max.
Capacitance 18 pf/ft nom.
Impedance 85 Ohms nom.
DC Resistance 4.1 Ohms/M' at 20oC
Flame Rating UL Vertical Tray
Black/Red Conductors

I was wondering what the 26/30 means. I know there's 2 conductors in the wire, but is each conductor 16 awg, or is it 16 awg combined? Should I rip this out and replace it with something better? Since it's already in the wall, it would be easy to pull it out and replace it. I'm also going to be moving all my equipment (receivers and htpc) downstairs, which is going to require a little modification to the wiring. The max length will be no more than 50 feet.

The reason why I'm asking is because I have Klipsch R3650's, which are rated at 8 ohms. I have an Onkyo NR5007 receiver, and in the setup, it shows the speaker impedance at 6 ohms. It makes me wonder if the wire that was used should be used for speakers, or just alarms.

Thanks!

Thanks!

It means - Each wire is 16 gauge, made up of 26 strands of 30 gauge bare copper.

I think I may have found my answer on wikipedia....

http://en.wikipedia.org/wiki/America...wire_AWG_sizes

For example, a 22 AWG 7/30 stranded wire is a 22 AWG wire made from seven strands of 30 AWG wire.

So, in my example, I have a 16 AWG wire that consists of twenty-six 30 gauge wires.
