T 21 SUB

21” premium hybrid subwoofer / 1.800W (RMS)

The T 21 SUB hybrid subwoofer combines the advantages of a deeply tuned bandpass technology with a long-throw effect and high dynamic range, which is typical for a horn-loaded design. The bandpass component ensures a balanced load of 21" membrane and suppresses membrane resonances at higher frequencies. The horn component produces a significant increase in efficiency and an impressive long-throw effect. The result is a very clean, deep and transparent bass. The T 21 SUB delivers with the unique hybrid design a perfect deep bass performance in both the near and far field. The high power cabability of 1.800 W (8 ohms) confirms the high standards of an uncompromising professional top-class subwoofer.

The T21SUB is a subwoofer system in a rectangular chassis for fixed installations and mobile use. The cabinet is equipped with a high performance 21" speaker (neodym). The integrated tripod base (M20) enables the use of a distance rod in combination with a MF/HF cabinet as a satellite system. The T21SUB suits for speech and music applications as real subwoofer speaker in sound reinforcement systems. The chassis is constructed from 18 mm plywood (birch) and covered with black PolyUrea© finish. The cabinet is equipped with four grip handles and a front grill with transparent charcoal foam backing. Two speakon connectors (NL4) are mounted at the rear side of the chassis for signal input (input) and signal link (link).
