Sub 22 DSP, Low Bass - Subwoofer with Top Performance.
One of the best subwoofers in its size      how to design a top-class subwoofer

technical data:
- Power: 200 Watt RMS/340 Watt peak
- Frequency response (-8dB): from 22 Hz
  (upper crossover frequency adjustable)
- Size (HxWxD): 94 x 38,4 x 39,4 cm
- Impedance: 4 Ohm

More and more customers are asking for a subwoofer where the cone's oscillation is controlled perfectly, reproducing a low bass and mountable in a small cabinet.

These requirements led to the following concept:
2 identical bass drivers with a very strong magnet and a very stiff and rigid cone, ensuring a controlled oscillation. A unique low bass control is added. The subwoofer is then combined with an amplification module with a very high power output. Sub 22

The Alcone AC 12 SW8 bass drivers are deployed in the Sub 22. The drivers are manufactured to the highest standards, ensuring first class control over the cone through their strong magnets.

The AC 12 SW8 bass driver consists of:

  • a seamless aluminium-sandwich cone,
  • an exemplary designed die cast basket,
  • ventilated magnet system
  • extremely strong drive Qts = 0,24,
  • 8 Ohm impedance, for optimum use
      of the amplifier by two AC12 connected in parallel.
  • gold plated push-pull terminals

    Particularly the strong drive combined with the low bass tuning, turn out a sound quality which is generally only possible with larger sized cabinets. The principle of low tuned subwoofers with extremely strong drive are at the moment being adapted by manufacturers of finished loudspeakers as well.


    The Omnes Audio DPA 200 amplifier module is located at the rear of the cabinet. The module features state-of-the-art amplifier with digital signal processor (DSP) ensuring enormous power output with top quality sound, fitted in a small cabinet.
    DPA 200

    According to the room acoustics the digital signal processor can be configured, giving you full control over the frequency response.

    Since two 8 Ohm bass drivers are used (resulting in total load of 4 Ohm), the entire power of the DPA 200 becomes usable.

    The kit consists of:
    - 2 x Alcone AC 12 SW8 bass drivers
    - 1 x Omnes Audio DPA 200 amplifier module
    - 4 x bass reflex tubes HP100, pointing downwards
    - 16 Allen wood screws 5x30mm
    - 12 wood screws Pan 4x20
    - 1 x mat needle felt
    - 8 cable fasteners
    - 1 x mat napped foam
    - sealing tape MDM-5
