DiMarzio® High Definition™ Speaker Cables are about as straight forward as you can get: 12 AWG OFHC copper, silver-soldered to gold-plated OFHC copper spade lug connectors. Teflon® dielectric and nylon overbraid: high-quality components constructed under the most rigorous standards. The result? A cable that transfers the amplifier's signal to your speakers as never before, extracting the last iota of resolution, increasing the apparent dynamic range and extending the frequency extremes with no trace of hardness or smearing.
