tatinc2000 Posted February 8, 2005 Share Posted February 8, 2005 Has anyone heard of using RG-6 for inwall speaker wire instead of speaker wire? I went to a home audio/video instal speacialist and they told me they use RG-6 for all their installs. Curios i went home and hooked up one speaker with 12ga moster and 1 with RG-6. The RG-6 one sounded much better. so far I've ran about 300 feet of RG-6 for speakers and was wondering if it weas a bad idea before I seal off the ceilings.

Champagne taste beer budget Posted February 8, 2005 Share Posted February 8, 2005 You could use coat hangers soldered together if you chose to, but I wouldn't advise it. Oh yeah, and welcome to the forum! I'd recommend using in-wall rated speaker wire, 12 or 14 gauge. http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=100-740 Since you are running this before putting up walls, I'd also suggest running PVC pipe through the walls so if you ever need to pull new wires for whatever reason, you can get the old out and new in easily.

Guest Anonymous Posted February 8, 2005 Share Posted February 8, 2005 the reason that you can use rg6 is because of its nomial impediance rating is constant and it has a strong unductance, meaning that it will maintain the signal almost all the way through, i personally would not reccomend it because it is really thin and it will stretchh out the bass but to each his own Quote Link to comment Share on other sites More sharing options...
michael hurd Posted February 9, 2005 Share Posted February 9, 2005 This is a poor idea, as the center conductor is 18 awg, this will limit the amount of control over the loudspeaker, also the capacitance is quite high in coaxial cable. We can look at the loudspeaker as a simple 8 ohm resistor ( not really, as speakers are reactive and always changing impedance ) in series with the outputs on the amplifier. Since power is equal to voltage squared divided by resistance, it can be seen that a 100 watt amplifier will develop 28.28 volts into an 8 ohm load. If we add 75 ohms in series with the simple speaker model of 8 ohms, then we end up with a load impedance of 83 ohms. The same amplifier develops 28.28 volts again, but with an 83 ohm load, will only deliver 9.63 watts. In effect, 90.36 watts are wasted in the cable.
