Speaker wire carries real current, so gauge, copper quality, and fire rating all matter more than most accessories. Here's what to buy for each kind of run.
The best speaker wire for most home theaters is MaxBrite's 12 AWG oxygen-free copper wire, which we use by default. It's UL Listed Class 2, so it's cleared for in-wall and in-ceiling runs.
For outdoor or buried runs, get GearIT's CL3-rated 12 AWG. To wire a whole system at once, Monoprice's 100-foot Access Series spool is the best value. For bookshelf speakers or a center channel close to the receiver, 16 AWG is enough.
Speaker wire carries real current, not a line-level signal — which means the physical length of the run and the quality of the copper inside the jacket have a real, measurable effect on how much power actually reaches the speaker. It's the one accessory on this page where "just buy something" can genuinely cost you performance.
Resistance builds up over distance, so a run that's fine at 16 AWG for 20 feet can measurably rob power over a 100-foot run to a rear surround or an outdoor speaker. As a rough rule: 16 AWG for short runs, 14 AWG for most rooms, 12 AWG once you're past 50–75 feet or driving a subwoofer or amp with real current on tap.
Oxygen-free copper (OFC) conducts efficiently and holds up over years of flexing and connecting. Copper-clad aluminum (CCA) is cheaper and often marketed right alongside it — it has meaningfully higher resistance and is more prone to breaking at the strands. Check the actual conductor material, not just whether the word "copper" appears in the title.
Beyond adequate gauge for the run and genuine OFC copper, thicker cable, fancier jacketing, or exotic marketing claims don't produce a measurable, let alone audible, improvement. Buy for the length and power you're actually running, not the specs on a premium box.

Why we picked it: This is the wire we reach for by default. It's 12-gauge, 99.99% oxygen-free copper, and already UL Listed Class 2 — meaning it's cleared for in-wall and in-ceiling runs without hunting down a separate fire-rated cable. A 50-foot spool covers a couple of speaker runs in a typical room without paying for length you'll never use.
Why it's on this list: Standard in-wall-rated (CL2) wire isn't rated for direct burial or real outdoor exposure — this is. GearIT's OFC line carries a CL3 rating that covers outdoor use, direct burial in ground, and in-wall runs in the same cable, with a UV-resistant jacket and foot markers printed along the length so you can measure a run without unspooling the whole reel. The right call for patio or backyard speakers, not just an indoor upgrade.
Why it's on this list: Monoprice is a trusted brand selling genuinely good basics without a premium markup. It's 99.9% oxygen-free bare copper, CL2-rated for in-wall use, and sold in a 100-foot spool — enough to wire an entire 5.1 or 7.1 system's worth of runs from a single purchase instead of piecing together several shorter cuts.
Why it's on this list: KnuKonceptz built its name in car audio, where delivering real current through tight, awkward spaces matters — the Kord line carries that over with a high strand count of oxygen-free copper that stays noticeably more pliable than stiffer bulk wire, which makes a real difference threading it through a tight run behind a rack or up a wall cavity. Reviewers consistently single out how easy it is to work with, on top of the copper quality itself.
Why it's on this list: Every other pick here is 12 AWG, which is overkill — and more expensive and harder to route — for a bookshelf pair or center channel sitting a short distance from the receiver. This is the same Access Series as our bulk 12AWG pick above, just in the gauge that actually matches a short run: 99.9% oxygen-free bare copper, CL2-rated for in-wall use, in a 100-foot spool.
