The vented SUB 18 and SUB 28 direct radiators have been designed for subwoofer use in active multiway systems. The superior transient response of the classic bass reflex construction is also well suited for medium to large bass arrays. The premium 700W RMS long excursion woofers feature extremely low THD, and the reliable, all‑electronic Voice Coil Tracking Protection prevents thermal overload of the 100mm sandwich voice coils. For maximum dynamics, the SUB models can be driven by extremely powerful amplifiers; thermal overload triggers a virtually inaudible power reduction.
