By PSW Staff • August 27, 2014 The new SUB 15H from dBTechnologies. dBTechnologies has recently upgraded their active subwoofer offerings with the new SUB H Series of 15-inch and 18-inch hybrid horn-loaded cabinets. The new design provides extended low-frequency range and high performance output while reducing the cabinet weight and increasing power efficiency. With a hybrid horn-loading designed cabinet, dBTechnologies was able to achieve a one octave lower frequency response then their previous offerings. The enclosure features a front sound wall that is slanted in the direction of the bass reflex ports. As a result, the air output is adjusted to the environment without any turbulence a minimal use of energy. “The enclosure can’t be considered a frontal loaded bass reflex nor a complete horn-loaded cabinet,” explains dBTechnologies product specialist Marco Cantalu. “It falls in the middle of the two. With the hybrid design, we are able to tune the cabinet down much lower than previous models, and be very efficient in the mid-long throw as well.” Compared to the previous SUB D Series, the new subwoofers actually use a smaller amplifier, providing better efficiency and power consumption while still achieving 133-134 dB maximum SPL output. Other upgrades include auto-range power supply for use worldwide; 56-bit DSP processing for crossover, EQ, limiter and delay management; Powercon link to connect with full-range cabinets; and mini-USB port to update system firmware and retrieve telemetry log files that provide service information on usage. The cabinets feature stereo inputs with selectable link or crossover outputs, crossover frequency switch (90 Hz or 120 Hz), phase inversion switch & built-in delay (up to 4.5 ms adjustable in 0.5 ms steps). The delay provides the ability to correctly couple with other full-range cabinets and set up advanced subwoofer configurations (cardioid, end-fire or straight line) without the need for external processors. The PVC-faced birch plywood cabinet is fit with polypropylene corners to provide road worthy protection. The cabinets have heavy duty aluminum handles, M20 thread mounts for full-range speaker mount combining, and optional wheels.
