Chassis: The Boston Acoustics
G5 series high-performance subwoofers are built upon a rigid cast aluminum
chassis. It features the patented RadialVent cooling technology which directs
airflow around the 2-3/4-inch voice coil for increased power handling.
Materials: The G512-4 woofer
has a co-polymer woofer cone with a raised polypropylene dustcap and a large
foam surround. The wrap-around gasket gives you a good seal whether you
top-mount or bottom-mount the woofer.
SPS (Soft Part System): The
woofer has a removable assembly which allows you to swap interchangeable parts
to make a different configuration, or service the woofer in the field. A 2.5mm
hex key is included for disassembly. Note: The replacement single voice coil SPS assembly
for this woofer is SPS-G5124 (item # 065SPSG512). You can also use the SPS-G51244 assembly (item # 065SPSG524) to change the woofer into a dual voice coil configuration.
SureSet: The speaker terminals
are equipped with two 7.5-amp ATC fuses providing voice coil protection under
transient conditions such as accidental momentary overdrive. Use of the standard
automotive style fuses allows you to quickly service the woofer in case a fuse
is blown during usage. Note: The fuses do not protect against voice-coil
failure resulting from long term high power abuse.
Terminals: The woofer has
rugged spring post terminals that accept up to 8-gauge bare wire or pin
Long Excursion: The woofer has
a 3-inch peak-to-peak excursion for accurate deep bass output from a small
GTR TunableRadiators: The
G512-4 is compatible with the Boston Acoustic GTR TunableRadiator (item #
065GTR12). These passive radiators, when mounted in an enclosure with the G5
woofer, can produce increased bass output without added enclosure volume. Note:
The manual provides several enclosure shape examples for mounting a G5
woofer with a GTR TunableRadiator.
Sealed Enclosure: The G512-4
woofer is optimized for use in a small sealed enclosure with a 1.0 cu. ft.
Ported Enclosure: The woofer
can also be used in a 2.0 cu. ft. ported enclosure with a 4" diameter, 14" long
