ESB Audio DBBurn DB2-6.5 — 6.5″ High-Efficiency Mid-Woofer (prijs per stuk) DB Burn Series 6.5″ high-efficiency driver. Italian engineering for SQL and SPL front stage builds. Built for the Passionate. Engineered for the Road. The ESB DB2-6.5 is a 6.5″/165 mm high-efficiency mid-woofer from ESB’s DB (DB Burn) Series — a purpose-built driver engineered for high-output, high-efficiency applications where maximum SPL from a compact chassis is the priority. Sold individually, not as a pair. The DB2-6.5 is designed for SQL and SPL-adjacent builds where the front stage needs to keep pace with serious subwoofer output. High-efficiency motor construction, rigid cone, and a voice coil assembly calibrated for sustained high-power operation without thermal compression. This is the driver for builders who want Italian engineering applied to the high-output side of the performance spectrum. Sold individually — order two for a stereo front stage installation. Compatible with high-power amplifier channels from the Zapco ST-X or Z-II series. The DB Series is ESB’s answer for builders who need both the quality of Italian engineering and the output levels of a competition-oriented driver. SQL
