Beyma 15B100 is back

elac310 · 12th June 2011, 11:21 AM

Just saw that one of the best 15'' soft suspension woofers ever made for HIFI usage, the Beyma 15B100, is back and available for instance from the following shop in Germany: 15" Basslautsprecher - STEREO LAB

Good news, which suggests that the audio DIY market is not doing that badly after all since the other former competitor, the French-made Audax PR380, has also been available for quite some time now (see for instance at http://audax-speaker.de/index.php?mo...articles&index[shop_articles][action]=details&index[shop_articles][category]=8&index[shop_articles][data][shop_articles_id]=109)

The exact ref of the Beyma re-edition is 15B100R-GH; the parameters seem to be slightly different from the earlier make, or I should say makeS; it seems that this model has quite evolved, as I can take when comparing the new data published for this latest edition, with the earlier initial data (see at www.beyma.com under discontinued pro products) and a first evolution in the 1990s or 2000s (http://www.beyma.de/index.php?id=80&L=1); in particular, if the Mms and Fs have remained fairly constant, the Vas shows variations between 400/600 liters for the previous makes, and about 250 liters for this new version.

Interesting. The parameters of the new version of the 15B100 are quite close to this Power 15 car woofer version (with the exception of the nominal impedance, obviously). The suspension of the car version seem to be rubber, whereas the HIFI version has, as far as I can see, retained the original foam version.

What is so great with this woofer really?

The original 15B100, with an Fs of 20Hz and its other parameters, was well designed to produce a clean, deep and punchy bass in a fairly large but still resonable volume.

Its parameters have evolved and - granted - this woofer presently seems not much different from a number of hard suspension 15inchers made today. At least on paper. It could be that the published parameters would still evolve significantly during burning in (I think soft suspension woofers evolve more than their hard suspension colleagues, lower Fs, higher Vas, lower Qts etc.).

In my mind, it remains a mytic woofer and it has always impressed me in the past.

To bad Fs and the price have gone so much up, the old price made it very attractive. But exiting driver anyway....
