ESB Audio 3.10D2 — 10"/250 mm DVC 2+2Ω Subwoofer | HF Audio
3000 Series 10" DVC 2+2Ω subwoofer. 1Ω parallel or 4Ω series wiring.
Built for the Passionate. Engineered for the Road. The ESB 3.10D2 is the 2+2Ω dual voice coil variant of the 3000 Series 10" subwoofer. Wire in parallel for a 1Ω final impedance — for amplifiers that are 1Ω stable and want maximum power delivery — or in series for 4Ω, the most common impedance for single-sub installations. Same 3000 Series construction and Italian-engineered driver quality as the 3.10D4. The choice between D4 and D2 comes down entirely to amplifier impedance compatibility: D4 for 2Ω parallel / 8Ω series; D2 for 1Ω parallel / 4Ω series. Choose based on your amplifier's rated stable impedance. Pair with a Zapco mono amplifier at your target power and impedance. An ESB 3000 Series front stage + 3.10D2 sub + Zapco mono amp is a cohesive, matched Italian system at a price that outperforms the competition.
