Shop B2 Audio at JS Ultimate Sounds — Danish-engineered subwoofers and amplifiers with a reputation earned in the SPL lanes. B2 builds motors for people who actually push their systems, and the brand has become a favourite for loud daily drivers and competition builds alike.
B2 Audio Subwoofers
B2 Audio subwoofers span the range from daily-driver bass to serious burp-lane hardware, with the RAGE and RIOT lines covering most real-world builds. Browse all B2 Audio subwoofers and pair them with a properly sized enclosure — box design decides as much output as the driver does.
B2 Audio Amplifiers
The RAVE series amplifiers are built to feed those motors: 1-ohm-stable monoblocks and multichannel models with the thermal margin to play hard. Browse B2 Audio amplifiers.
B2 Pro Audio
B2's 8" pro audio speakers bring high-sensitivity midbass for front stages that keep up when the subs come alive.
