Low End You Can Feel
Bass Built for Daily Driving and Competition
Controlled Low End
Designed for tight, repeatable bass rather than one-note boom, so basslines and kick drums stay separate.
Built to Take Power
Voice coil, spider and cone materials are matched to the rated RMS so the sub handles sustained output.
Match the Enclosure
Performance depends on the box. Sealed for accuracy, ported for output. See the specs for recommended volume and tuning.
Wire It Right
Coil configuration decides your final impedance. Match it to a load your amplifier is stable at before wiring.
