dB Technologies recently upgraded their active subwoofer offerings with the new SUB H Series of 15” (pictured here) and 18” hybrid horn-loaded cabinets. The new design promises extended low-frequency range and high performance output while reducing the cabinet weight and increasing power efficiency.
More details from dB Technologies (www.dbtechnologies.com) and RCF USA (www.rcf-usa.com):
With a hybrid horn-loading designed cabinet, dB Technologies was able to achieve a one octave lower frequency response then their previous offerings. What is hybrid horn-loading?
“The enclosure can’t be considered a frontal loaded bass reflex, and neither a complete horn-loaded cabinet,” explains dB Technologies product specialist Marco Cantalu, “putting it 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.”
In the cabinet design, the front sound wall is slanted in the direction of the bass reflex ports. Through this, the air output is adjusted to the environment without any turbulence and the energy is conserved much better.
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.
