ENCLOSURE CONSTRUCTION
The dimensions shown in the tables are intended as a guideline and specific dimensions (HxWxD) may be changed provided
the internal volume of the enclosure is maintained. For best performance the walls of the enclosure should be rigid and not
vibrate as a result of the internal pressures generated by the loudspeakers. BRAVOX recommends constructing enclosures
from medium-density fiberboard (MDF) with a minimum thickness of 3/4”. In larger enclosures over 1 cubic foot, internal bracing
that joins opposite walls can be incorporated and the final enclosure should be as rigid as possible. All joints should be glued
and fastened with screws. Additionally, internal joints can be covered with a small bead of silicone adhesive to ensure that the
enclosure is completely airtight. Drivers should be fastened to the enclosure with self-threading screws with adequate length
and diameter, utilizing all the mounting holes in the frame. To avoid air leakage, a foam rubber gasket or similar sealing method
should be applied between the loudspeaker and the enclosure. The external surface of the enclosure may be painted or
fabric-covered, to suit the consumer.
Since low frequency sounds are not directional, subwoofer enclosures can generally be placed anywhere within the car, without
compromising stereo imaging. While the trunk is the most obvious location, locating them behind the seats is another possibility.
However, different placement locations of subwoofer enclosures can sometimes influence the overall quality of bass/midbass
response. As interior acoustics are different for each vehicle, you may wish to experiment with various mounting locations
before permanently mounting the woofer.
