Introduction
Please read this manual carefully before using the product. This will give you
the necessary product and installation instructions to assure a seamless
installation and non-compromised overall sound quality.
Thank you for purchasing the loudspeakers of the SUB series. The SUB2400
subwoofer has two bandpass chambers and each chamber is equipped with a 10”
dual coil woofer. Together with the push-pull technology, this results in a
relatively small cabinet with a huge output and very low distortion. Thanks to
the small size of the woofers, less mass has to be moved. The bass
reproduction is a lot more “punchy” and “faster” compared to 15” or 18”
cabinets. The SUB2400 has been compared with single 15” and 18” subwoofers and
the results were astonishing in favor of the SUB2400!
SUB2400 can be driven at 4 ohms or 16 ohms. Selection is done by the large
switch at the back of the subwoofer. Especially with long cable runs, the 16
ohms mode is advised. Less power is lost and the bass response will be a lot
better. The 16 ohms mode also allows you to use multiple cabinets.
Safety instructions
- Keep this manual for future reference.
- Take care of your speaker wires, they should be free of damage. Damaged speaker wires may result in poor sound quality and can damage amplifiers.
- No main power shall be connected to the speakers, doing so will damage the speaker.
- This speaker should only be serviced by qualified personnel. If not, the warranty might be void.
- Use cables of the right gauge, certainly for long runs.
- Use cables with clear color indication and maintain polarity throughout the whole system.
- Avoid loud feedback for this is the main speaker killer.
- Clean only with a dry cloth.
- Do not operate near heaters or place it on other apparatus which produces a lot of heat.
- Only use accessories specified by the manufacturer.
- Make sure the mounting surface can easily support the speaker’s weight.
- Use only industry-accepted rigging tools and methods.
- Use sufficient loudspeakers and avoid dead spots.
- Being exposed to loud levels over a long time can cause severe hearing loss.
- Don’t forget to consult the local law directions regarding producing sound in public places.

Installation
The two Speakon connectors are wired in parallel. The rocker switch gives you
the possibility to turn your SUB2400 into a 4 or 16-ohm version.
To get the best result in producing low frequencies, you should keep the
minimal impedance of your subwoofer system as high as possible, certainly when
cables of more than 10 meters are used. Four subwoofers at 16ohm will produce
a higher sound pressure than two subwoofers at 4 ohm. The 16-ohm subwoofer
will also draw less power from your power amplifier! The -1/-2 and the +1/+2
Speakon connectors are wired in parallel.
Recommended cable length vs. load vs. cable diameter.
| Load | 2.5 mm² | 4 mm² |
|---|---|---|
| 2 ohms (2 x SUB2400 at 4 ohms) | < 7.5 m | < 12.5 m |
| 4 ohms (4 x SUB2400 at 16 ohms) | < 15 m | < 25 m |
| 8 ohms (2 x SUB2400 at 16 ohms) | < 30 m | < 50 m |
| 16 ohms (1 x SUB2400 at 16 ohms) | < 60 m | < 100 m |
