Acoustic Design & Powerful Performance
The SUB 28 D utilizes a high-efficiency bandpass design housing two 8-inch woofers, driven by a reliable Class-D digital power amplifier that produces 400 W RMS (800 W peak) of dynamic output. Capable of reaching a maximum SPL of 125 dB, it ensures solid, impactful bass response down to 45 Hz. The integrated digital stereo crossover (DSP) makes it straightforward to configure mono or stereo satellite systems seamlessly.
Key Technical Features & Signal Processing
- Dual 8” Woofers: Custom-engineered drivers built into a slim cabinet footprint to maximize low-frequency punch and efficiency.
- Digital Stereo Crossover (DSP): Features a 24-bit / 48 kHz digital processor with selectable crossover frequencies (LF-MF setups) and a 24 dB/octave slope for clean signal separation.
- Dual Active Limiter: Protects internal components against distortion and thermal overload during demanding performance sessions.
- Flexible Phase Control: Easily switch phase polarity between 0° and 180° to achieve optimal phase alignment with your main satellite speakers.
