Power Handling Note
Dual Voice Coils: For increased
system flexibility, the woofer has two 4-ohm voice coils. When the voice coils
are wired in parallel, the woofer presents a 2-ohm load. When the voice coils
are wired in series, the woofer presents a 8-ohm load. In addition, each coil
may be connected to a different amplifier channel and each channel will see a 4-ohm
Cast Basket: The dual voice
coil woofers use a polished chrome aluminum 6mm cast basket. This ensures a
perfect alignment on each and every woofer. Unlike stamped baskets, the cast
basket cannot bend or tweak. Rigidity is important when trying to achieve strong
bass and high SPL.
Flame Basket: Audiobahn's Flame
series cosmetics are integrated into the cast aluminum basket, the back cover on
the magnet, and the cone.
Aluminum Cone: This woofer uses
a stamped and balanced aluminum cone. Aluminum cones are light, fast and
accurate for excellent sound quality.
Surround: This woofer has a
PHAT 2" multi-layer foam surround.
Magnet: This woofer has
120-ounce double-stacked strontium magnets, giving it superior power handling
Vented Back Plate: The back
plate is vented to ensure efficient cooling of the voice coil.
4-layer Voice Coil: This woofer
has a 2.5" 4-layer voice coil.
Chrome Finish: This subwoofer
has a protective chrome finish.
Speaker Terminals: Each voice
coil is equipped with Audiobahn's patented Multi-connect Lug Lock speaker
terminals, giving you 4 inputs (2+, 2-) for each voice coil. Each terminal can
accept bare wire up to 8 gauge. The wire is held in place by tightening Allen
Head bolts using the included 4mm Allen wrench.
Wooden Box: Each subwoofer is
packaged in one of Audiobahn's trademark wooden boxes.
Recommended Ported Box
Volume: For best response and sound quality, Audiobahn recommends a ported
enclosure with an internal volume of 2.3 cu/ft with one 4" diameter x 7.25" long
port, so that is the enclosure recommended by Crutchfield. If box space is lacking in the vehicle, Audiobahn suggests a "Space
Saver" box can be used with an internal volume of 1.3 cu/ft with one
3" diameter x 6.75" long port. For high performance applications, Audiobahn's
"Ultimate SPL" box design has an internal volume of 3.2 cu/ft with two
4" diameter x 12" long ports.
Recommended Sealed Box
Volume: This woofer is best suited for ported box applications; with
all other factors being equal, the woofer will sound better in a ported box than
it will in a sealed box. If you must mount this woofer in a sealed box,
Audiobahn recommends a sealed enclosure with an internal volume within the range
of 0.5 cu/ft to 1.25 cu/ft.
Handling: The woofer has two 4-ohm voice coils, and each coil
can handle up to 550 watts RMS (1100 watts peak).
