Building Instructions Sub 22 DSP

The assembly of the cabinet

The Sub 22 consists of 6 external panels and 8 internal bracing panels which reduce the intrinsic resonance of the wooden cabinet. All 14 panels should be glued together and attached with screws (if required). Afterwards - or before - 6 openings for
- the bass drivers,
- the amplifier module and the panel (front),
- the bass reflex ports, underneath
should be cut.

Then the feet should be mounted. The distance between cabinet and floor tunes the loudspeaker, since this represents an extension of the bass reflex tube. Should the speaker be positioned close to a corner, the feet may be shortened by 5 mm.

Bass reflex tube tuning

To be able to tune the loudspeaker accurately to low frequencies, a long bass reflex tube is needed. This can be achieved by connecting the 4 supplied tubes HP 100. We suggest to fit the first two tubes from below; the remaining 2 should be attached (with textile sticky tape, plastic glue,...) to the first 2 by using the bass driver opening.

The assembled bass reflex tube should then be wrapped once with needle felt and secured with cable fasteners.

The Omnes Audio DPA 200 bass response is tuneable. We suggest, however, to try the neutral default setting first. For lowest bass and highest sound pressure level this seems to us the best setting.

Operation

The subwoofer needs to be connected to the amplifier (via cinch cable to the pre-out terminal or with speaker cable to the (satellite) speakers and the mains cable to the wall plug....

We wish many hours of enjoyable listening with this amazing subwoofer! - Should there be any questions left, please call tel: +49-721-9703724.
