dB Technologies SUB 28 D active 2x8 Subwoofer

Even though it’s the smallest of all dB Technologies active subs, the Sub 28D is actually packing two drivers!  Two 8” woofers are powered by an 800 Watt Digipack digital amplifier, making the Sub 28D a compact but incredibly effective low end solution!

The Sub 28D integrates easily into most satellite systems but is specifically designed for the dB Technologies L and K series speakers.

The Sub 28D inputs on two balanced XLRs and outputs on two balanced XLRs.

Why choose dB Technologies Sub series??

This active sub range from dB Technologies tick a lot of boxes when it comes to subwoofers; powerful, portable, durable.  But what are their USPs?  Why should you invest in them over other brands?  Well there are a number of reasons why, all in the form of different technologies that make the basic building blocks of the series.  Some are dB Technologies own patented designs, others are the manufacturers take of common technologies, all combining to create powerful PA subwoofers that are simple to use, pleasing to hear and you’ll be proud to own.

Digipro® – dB Technologies own power amplifier design that cuts down on power consumption and heating.  It has an amazing 1:1 power output to weight ratio!

Digipack® – dB Technologies own power amplifier design that packs all the same punch that the Digipro does but in a more compact design for small subs.

DSP Processing – this acts as an active crossover and controller for the amplifier, splitting and limiting the signal and aligning the phase and delay times to ensure optimum performance. 

Multiband Limiter – this limiter protects the speaker’s internal components and maintains sonic quality and system stability when it is ‘under stress’, i.e. outputting at high levels for long periods of time.

H.E.T Housing – “Hybrid Enclose Technology”.  This highly effective cabinet is made from multiple wood types with a durable and scratch resistant coating.  In addition, the cabinet is sandwiched between two rugged plastic side panels that further strengthen the unit, improve its acoustic characteristics and make it even more road worthy!

SMPS – stands for ‘ultra efficient switched mode power supplies’.  This ensures optimum performance of the monitor even when plugged into poor quality power supplies.
