Speaker wire question

[RHINES4]

Hello all,

I just purchased Polk Rm6750 speakers to go along with a Sony Strdg820 and have a few questions.

What size wire would be best to use? (12, 14)?
Besides the HDMI cable are there any other cables i'll need?

thanks much for the help.

You can use either 14 or 12 gauge speaker wires. However, go with 12 gauge. The difference in price is very little. You can go longer with 12 gauge wires and 12 gauge wires are better for low impedance speakers.
Read A Guide to Optical, Coaxial, & Speaker Cables. It has a table that you can use as a guide.

You need at least 2 HDMI cables. One to connect the BD player to the receiver and another to connect the receiver to the TV. You also need a subwoofer cable to connect the receiver to a powered subwoofer. Buy a Subwoofer cable that is shielded properly. Monoprice.com is the best source for reasonably priced cables.

If you do go with 12 gauge, I'd recommend to get some plugs for them. 14 gauge honestly is a little tough to fit into the speaker terminals as it is.

An example of them is here: http://www.amazon.com/Audioquest-UST...8099464&sr=1-9 though I wouldn't actually recommend that exact item.

Thanks guys, I planned on using banana plugs.

Which One Have you whether to decide to go for 12 or 14 or 16 gauge ? Mine too soon to have Polkaudio FloorStanding even others the more speaker for soon !

can you use bananas on the polk rm speakers?

Don't buy a monster cable or wire. the business tried to trick you.



Wire Table
In the early speaker manuals, starting with the XR5, I included a chart for estimating the maximum wire lengths for various sizes of copper wire needed for 4 and 8 ohm loads. I have expanded it on this page to include 2 and 6 ohm loads as well. It was based on the resistance of the speaker wire not exceeding 5% of the rated impedance of the system. The wire length is for TWO-CONDUCTOR wire. This includes one wire out to the speaker and one wire back again.
Wire is specified by gauge numbers. A smaller number indicates a larger diameter of wire and consequently a lower the resistance. Stranded wire is composed of several smaller conductors. The total cross sectional area of all of the smaller conductors determines the effective wire size of the stranded wire and it will have lower resistance than only one of the strands. This is analogous to resistors in parallel.
Maximum Wire Lengths For TWO CONDUCTOR Copper Wire
Wire Size 2 ohm load 4 ohm load 6 ohm load 8 ohm load
22 AWG 3 feet max 6 feet max 9 feet max 12 feet max
20 AWG 5 feet max 10 feet max 15 feet max 20 feet max
18 AWG 8 feet max 16 feet max 24 feet max 32 feet max
16 AWG 12 feet max 24 feet max 36 feet max 48 feet max
14 AWG 20 feet max 40 feet max 60 feet** 80 feet**
12 AWG 30 feet max 60 feet** 90 feet** 120 feet**
10 AWG 50 feet max 100 feet** 150 feet** 200 feet**
