Executive Overview

foamlessThe Westlake Audio BBSM-10VNF is a floor standing version of the classic BBSM-10 monitor. The 3-way system uses dual 10" woofers, a 6 1/2" cone midrange and 1 1/4" soft dome tweeter in a ported enclosure. The frequency response is spec'ed at 40-18K which is surprisingly honest for a speaker at this price point. For that alone Westlake Audio has piqued our interest. Of course, all the foam stuff turned us off. Fortunately, it is optional. The North American Walnut cabinet features extensive internal bracing with proprietary sound dampening materials that virtually eliminate any cabinet distortions. All crossover components including hand wound coils; capacitors and resistors are matched within a 1% tolerance to ensure balanced response.

We talked about the foam over at the Lansing Heritage forum and some of us thought it was for dispersion control, some foams can act as a lens.

Back in the 70s and 80s EV used a foam lens that covered a large dome tweeter (Superdome) leaving a small hole in the center, it looked like a foam bagel. The lower frequencies from the dome passed through the foam but they higher frequencies came only through the small hole thus making for wider dispersion than a dome that size would normally have. This device allowed EV to use a larger than normal dome (and thus get higher output and a lower crossover than most domes) and still have wide dispersion.

The working of the lens is explained in this sheet from the EV archives.
