ENCLOSURES

BRAVOX ULTIMATE PERFORMANCE PLUS SUBWOOFERS have been specially designed to produce outstanding results in both small volume sealed and small volume vented enclosures. While it is possible for the advanced installer to use the Thiele/Small parameters provided in this manual to design their own enclosures (for

thmore on "doing it yourself", check out Vance Dickason's Loudspeaker Design Cookbook, 6 Edition at www.audioXpress.com), all this work has been done for you and provided in the recommended enclosure charts. The choice of which type of enclosure, vented or sealed, is strictly up to you. As a rule, sealed enclosures provide better transient bass response than their vented counterparts, although the vented enclosures generally provide more deep bass. Your choice should be based on the amount of space available and the size of the vehicle. In general, smaller vehicles (Corvettes to Camry's) probably work best with sealed enclosures while larger vehicles such as SUV's, Vans, large trucks or RV's can benefit from the kind of performance available from vented enclosures. However, both enclosure types will work in any situation.

SEALED ENCLOSURESThis enclosure is made up of a totally closed, air-tight box. This type of enclosure gives excellent, tight bass response, as well as providing an effective control of loudspeaker excursion, maintaining it within reasonable limits and generally providing lower distortion and very high volume levels. If you build your own enclosure, BRAVOX recommends that you glue and screw all joints using enough glue to ensure that all joints are air-tight.

VENTED ENCLOSURESVented enclosures are not air-tight and incorporate an additional opening known as a port or vent, which is generally fabricated from either plastic or cardboard tubing. The port augments the sound coming out of the woofer and is in most cases capable of going lower in frequency than the same woofer in a sealed box. Even though vented enclosures are not air-tight, you should follow the same procedure as with sealed boxes and glue and screw together all joints.

The tables below give the internal volume (Vb) in cubic feet and liters for sealed and vented enclosures, each specifically designed for the ULTIMATE PERFORMANCE PLUS SUBWOOFERS. Sealed enclosures were calculated for flat response (Qtc in the region of 0.7) but smaller volumes can also be used when an "enhanced" bass response is desired. The flat response enclosure provides more accurate bass while the smaller "enhanced" bass enclosures are somewhat less accurate, but have marginally increased power handing. For vented enclosures an "enhanced" bass response enclosure can be designed as well, but in this case, rather than changing the volume of the enclosure, a different tunning (vent length) is used. In table bellow, the longer vent leads to a flat response whereas the shorter one refers to "enhanced" bass enclosure.

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 air-tight. 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.

WIRING.

ULTIMATE PERFORMANCE PLUS SUBWOOFERS are offered in Dual Voice Coil configuration in two versions, 2+2 and 4+4 ohms. This allows the user to create virtually any impedance load to match his amplifier.
