dBTechnologies' new Sub 18 H offer remarkable specifications and user-friendliness. With 1000W (1400W Peak Power) and a high-performance 15" woofer with 3" coil, the Sub 15H is especially suited for small to mid-sized events, where high performance needs to be packaged into compact size. Whenever a lower extension is required, the perfect choice is the new Sub 18H, equipped with a 1500W (2000W Peak Power) power amplifier and a high-performance 18" woofer with 4" coil.  
Thanks to their unique configuration, termed Hybrid Horn-Loading, the boxes can be tuned to the lowest frequencies to improve system efficiency and convey a deep, enveloping sound. Unlike conventional horn loaded systems, 15H and 18H subs ensure excellent efficiency even at close listening distance, which makes them suited for use even in small venues.
