REF8W

2020, a new decade has begun & with it B2 audio has introduced yet another innovative item. The REF8W, Initially meant as an add on to the beloved Reference 3 way sytem. Some newer cars come with 8″ speakers as standard, thus our new 8″ immediately became the preferred choice for upgrades. Featured in the Reference line up equals a no compromise take on the R&D. We already have 2 8″ woofers in our product category, so this loudspeaker had to be more than just that. The 40 Hz ~ 6 KHz frequency response nearly makes this driver a fullrange.

Any Application

This design offers superiority in various applications. Woofer, Midwoofer, Midrange, you name it. The REF8W is built on the principles of home audio. Efficiency, physical dimensions & acoustics are all cornerstones in this loudspeaker.  And as such it can easily be paired with existing systems or as an add on. Both the REF63 and the RAGE63 can be had as a 3 way featured with this 8″ driver, but it can also be complemented with it, reproducing the low frequecy response without the need for large enclosures.

The Tech

Optimizing the suspension by choosing a narrower voice coil (2″) may cause you to question the powerhandling. Using an old trick we circumvented that by extending the voice coil winding height by 100%. Might be easy, but doing it without increasing the mounting depth (only 4.2″ / 108 mm) requires a precision wound coil, with windings on both the inside and the outside of the former. The side benefit is that efficiency is better than simpler traditional designs. The composite cone and dustcap extends the efficiency as they are stronger and more lightweight than conventional cones which can offer greater transient response. All mated with a FEA designed motor with a ventilated pole piece and a copper shorting ring, lowering audible distortion. But no premium product from B2 audio is complete without some swag. The REF8W comes in a custom made flightcase with softcell black foam just because we can.

*It is essential that our speakers are given time to allow the suspension to soften up. Depending on use, this may take several weeks. While this process is undergoing, it is not recommended to apply full amplification power according to the speakers specs. Once the moving parts have been broken in, the performance of your speaker will increase.
