CABINET CONSTRUCTION TIPS
When building a passive speaker cabinet, the following points should be borne in mind:
1. Use 19 mm thick (or 22 mm is preferable) chipboard or MDF to make the cabinets.
For particularly large cabinets or heavy woofers, the baffle can be doubled (e.g.
2 x 19 mm).
2. Maximum stability is achieved by gluing the boards together under pressure (wood
glue) and then screwing them together using wood screws. The screws should be
inserted at approx. 10 cm intervals.
3. The specified dimensions of the bass reflex tubes may fluctuate by a maximum of
10 %.
4. After assembling the cabinet, make sure that it is airtight; touch up with silicone if
necessary.
5. Medium-thick polyester wool or foam insulation is advisable for enclosed cabinets.
Bass reflex cabinets only require single insulation on the internal walls of the cabinet.
On no account may the reflex opening be blocked.
POSITIONING AND SECURING THE SUBWOOFERS
Ensure that the subwoofer cabinet rests on an even surface. The cones (and, where
applicable, the bass reflex tube) should not be placed directly against the car’s interior
walls.
Make sure that the subwoofer is secured in such a way that it cannot slip or slide.
Damage resulting from sudden changes in speed (e.g. hard braking) is not covered
under the terms of our guarantee.
