B2 audio Extraordinary Level subwoofers, covers all your needs to fire up your passion and bringing it to the next level.
Where others settle for less, the EL series is the result of extensive research of what we can offer regardless of cost.

Features such as oversized multilayer progressive spiders, clamped & glued spider rings, woven in tinsel leads & high temperature precision wound dual voicecoils are all attributes of high end drivers. This series features all of these, but we always push the boundaries and do not settle for the norm. Yet a reason why we opted for non pressed paper cones to reproduce a smooth natural sound, instead of commonly used plastic types.

The FEA designed motor now boast 100 Oz magnet slugs, which has also increased the xmech and the xmax of the drivers, which again equals to more pressure moved.
To help keep the voicecoil in check and from overheating, the motor has both a vented pole and a drilled backplate with airvents, but that’s just the technical details of the these subs.

The audiophile performance is what really makes the EL & ELSQ outstanding. Sealed, vented or even bandpass enclosures do all comply with these drivers for both SQ and excessive bass. The efficient design makes them perform better on lower power compared to other subwoofers. The 500W rating (1000W peak) makes it perfect for amps up to 1kw.
These subwoofers already gained a world record in a lower powered trunk clamped class, so don’t think you are settling for less, when in fact you are getting more than you would expect.

Extraordinary Level is where the bar is set now!
