Product Overview

Active 2 x 8 Subwoofer

We engineered the SUB 28 D to provide low-end reinforcement for compact satellites such as dBTechnologies L and K Series speakers. This light and lean enclosure houses two 8“ woofers driven by a 400W digital power amp and an onboard digital stereo x-over. Setting up mono and stereo satellite systems is a piece of cake with this amp and DSP on board.

The Subwoofer Company
dBTechnologies is well known for its remarkable active subwoofers with outstanding performance, combining powerful and precise subsonic reproduction with excellent tonal quality. The dBTechnologies’ bandpass design guarantees a well balanced reproduction of sound but adding a few dB SPL extra, compared to regular bass-reflex designs. The result is maximum performance, out of a very compact and lightweight enclosure.

Active Crossover – Easy Setup
All powered subwoofers are equipped with an active crossover, which can operate in Mono or Stereo mode, providing all combinations for applications with one or more subwoofers.

digipro® digital amplifiers – More power and less weight
