Every musician searches for their distinctive voice, and tone. Ironically, the reason many artists find it in the B412 is that it accurately reproduces what is already coming out of your amp. The enclosure is air sealed with silicone to maintain consistent air volume, creating an air spring to prevent the speaker from excess travel. The result is less speaker distortion at extreme low frequencies and extreme volume. This consistency combined with 300 watts of power handling makes for a cab low enough for the 7-string enthusiast, and clear enough for the clean tone soloist. Features removable casters, available in black or gray mesh
