Overview

The Monoprice Planate Series 16AWG flat speaker wire is engineered for audio installations where aesthetics matter as much as sound quality. Its flat cross-section allows the wire to be tucked beneath carpet, run along baseboards, or painted over when mounted on walls, keeping your listening space free of visible cable clutter. Unlike many budget speaker wires that use copper-clad aluminum (CCA) conductors, this cable uses pure bare copper throughout, which provides superior electrical conductivity and lower resistance. The practical result is more faithful signal transmission between your amplifier or receiver and your speakers, particularly on longer runs where CCA wire would begin to show measurable losses.

The 100-foot spool arrives with a CL2 in-wall safety rating, making it suitable for permanent installation inside walls and ceilings in compliance with building codes. Each conductor pair features printed markings on one wire for easy polarity identification, a small but important detail that prevents phase issues when wiring multiple speakers. The PVC jacket protects the copper from oxidation and physical damage during installation. Whether you are setting up a home theater, running speakers to another room, or replacing aging wire in an existing setup, this flat speaker wire combines practical design with reliable performance at a price point well below specialty audio cables.

Pros & Cons

👍 Pros

  • Pure bare copper conductors provide lower resistance and better signal integrity than cheaper copper-clad aluminum alternatives
  • Flat profile sits flush against baseboards, under carpet, and along walls for nearly invisible installation
  • CL2 in-wall rating allows safe permanent installation inside walls without requiring additional conduit
  • Conductor markings on one wire make it simple to maintain correct polarity throughout the entire run
  • 100-foot spool length provides generous cable for most home audio setups

👎 Cons

  • 16AWG gauge may introduce noticeable signal loss on runs significantly longer than 50 feet to lower-impedance speakers
  • Flat design is less flexible around tight corners and bends compared to round speaker wire
  • PVC jacket is functional but not as durable as braided or heavy-duty outer sheaths used in premium cables
  • Only available in a single 100-foot length, so shorter or longer needs require cutting waste or purchasing multiple spools

Frequently Asked Questions

Yes, the Monoprice Planate Series 111936 carries a CL2 rating, meaning it meets safety standards for installation inside walls.
Pure bare copper has lower electrical resistance than CCA, which means less signal loss over long runs. This results in more consistent audio quality, especially at longer distances between the amplifier and speakers.
One of the two conductors has cable markings printed along its length, making it easy to maintain consistent polarity when connecting to amplifier and speaker terminals.
The spool is 100 feet, which is enough for most multi-room or single-room installations with wire to spare.
16AWG is suitable for most home audio speaker runs up to about 50 feet. For very long runs or high-power applications, thicker gauges like 14AWG or 12AWG may be more appropriate.
