Boston Acoustics SPG555 - Manual (Page 6)

RVC ™ (Removable Voice Coil)
Removable Voice Coil
The SPG555 is the first woofer ever that allows the voice coil to be exchanged without having to
remove the woofer from the enclosure. This unique feature allows you to change the impedance of
the woofer or repair a damaged voice coil, not just easily, but quickly.
Removing The RVC ™
1) The RV C ™ is held in place with six screws. Using the provided tool (2.5mm allen hex), remove the six
screws around the outside of the RV C ™ .
2) Once the screws are removed, pull up on the handle and the RV C ™ will slide out .
 
Note: If the previous RVC ™ was damaged, make sure that the gap is clear of all debris before installing the new RVC ™ .
Installing The RVC ™
1) Install the new gasket (provided) on to the RV C ™
.
2) Align the notches on the RV C ™ with the insets on
the SPG555 cone (the RV C ™ is keyed for proper
orientation and will not seat flush or seal into the
cone if the RV C
™ is not properly positioned).
3) Once the RV C ™ is seated to the cone, hand tighten
the six screws , do not over-tighten the screws.

Installing The Handle
1) The handle is held in place by two screws
(included in the handle bag). The handle can be
positioned on one of eight different ways
.
2) Line up the handle with two of the six screw
holes on the RVC ™ . Using the provided 2.5mm
tool, hand tighten the screws . The specific
orientation of the handle will not effect per-
formance, however, to ensure proper tuning,
must be installed prior to using the SPG555.
Warning: Choose the position of the handle wisely.
Installing the screws into the RVC
™ will mar the area around
where the screw is installed. Although not visible with the
handle installed in the original position, if the handle is
moved, you will be able to see the enlarged screw holes
from the previous install position.
