B2 Audio XM 4000 RMS 18 Inch Subwoofer

Above Excellence

Spawned from «the first of the five – X2C» we created the XM, a subwoofer sharing many of the ideas from the X2C, but scaled down to a 4″ voice coil.
With the same SAFT* design basket on the 15″, airflow is optimized for best possible cooling and increase in dB.
Both XM drivers also inherited the OCAF* motor design that allows for both longer excursion and minimizes heat and distortion.

4 Ga push terminals connects to the heavy duty quad multilayer and high strand count tinsels.
They ensure power is fed to the 4″ ceramic coated voice coil with minimum amounts of loss.
Tall & narrow foam surrounds on ultra condensed fiber blended cones, with 100% progressive Nomex spiders will keep long excursions in check,
and the 8″ carbon fiber dustcap stabilizes the cone further.
