Building Instructions Sub 8

The assembly of the cabinet

The Sub 8 consists of 6 external panels. All 6 panels should be glued together and attached with screws (if required). Afterwards - or before - 3 openings for
- the bass driver,
- the amplifier module,
- the bass reflex port
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 2 supplied tubes HP 70. We suggest to fit the first tube from below; the second one be should attached (textile sticky tape, plastic glue,...) to the first tube by using the bass driver opening.

The remaining part is relatively easy: the amplifier module needs to be mounted and afterwards the bass driver since it is a lot easier to connect the bass driver when it's not mounted yet. The red / black cable's plug at the DT 80 should be pressed together or simply cut off

The bass driver should be attached last.

The DT80' 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....
