Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Woofers: The VRiSub82 in-wall
subwoofer uses dual 8" cast DCD copolymer woofers. The subs are mounted to a massive cast
aluminum baffle for rigidity and low resonance.
Inputs: Spring loaded posts
will accept pin connectors, or bare wire up to 12 gauge.
Paintable: Both the frame and
grille can be painted to match the ceiling or wall. A plastic paint shield is
included to protect the drivers.
New Construction Bracket: For
new construction installations, the NCBTL8 in-wall Installation Bracket (item #
065NCBTL8) is needed.
Recommended Amplifier: The VRiSub82 sub is designed to work with the Boston
Acoustics SA1 sub amplifier (item # 065SA1). Use with any other amp will result in poor performance
and may cause damage to the sub. One SA1 amp can run up to two VRiSub82's.
Overview: It is the nature of
bass to cause objects to vibrate. Care should be taken in planning the
installation of an in-wall subwoofer to minimize the risk of room vibration and
noise. Here are some tips to consider:
- Location Hazards: Do not
locate the subwoofer in wall cavities that contain ducts or grilles. Do not
locate the sub close to wall-mounted light fixtures, grilles, or other
wall-mounted objects that might vibrate. Check both sides of the wall for
objects that might vibrate.
- Wall Materials: It is
recommended that the sub is only installed in walls with a solid surface
such as wallboard, wood, or masonry. Do not install the sub in walls
constructed of lath and plaster. Extra care must be taken with walls with
steel studs to confirm that any studs that touch each other are screwed
together and that all studs are screwed to the Sheetrock. Note:
Consult local building codes for compliance.
- Placement: The VRiSub82
should be located in full-height wall cavities to achieve a minimum cavity
volume of 2.5 cubic feet. Do not locate two Sub82's in the same wall cavity or
in the same wall cavity of any other speaker.
- Wall Dampening: The
performance of the sub will be enhanced if the wall cavity is filled with
standard fiberglass insulation.
- New Construction: Taking
steps to increase the rigidity of the mounting surface will enhance the
performance of the sub. Using additional drywall screws, using
construction adhesive between the drywall and studs are useful techniques.
Wall Thickness: With the
supplied hardware, the sub can be installed into walls with a surface thickness
of 1/2" to 1-1/4". With the thicker surfaces, you will need longer screws. It
is not recommended to install this sub in walls where the thickness is less than
Installation: After a
19-7/16" x 11" cutout is made (either vertically or horizontally), the speaker
is installed in the hole and held in place by a rugged plastic screw-set
bracket. The only tool required (after the hole is cut) is a #2 Phillips head
screwdriver to tighten the clamps. The clamps spread up to 2.220", so they
should cover almost any application (most drywall is 1/2" thick). The required
depth to install this speaker is 3.75".
Note: There must be 1-1/2"
clearance around the mounting hole on the long axis to accommodate the
