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 loudspeakers of the SUB series.
The SUB2400 subwoofer has two band pass chambers where each
chamber is equipped with a 10” dual coil woofer. Together with
the push-pull technology this results in a relative 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 a single 15” and
18” subwoofers and the results were astonishing in favour 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.

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
