Jamo R909 woofer?

cyclo · 4th January 2006, 07:45 AM

This Jamo looks very interesting: not too wide baffle with 2 x 15" by side. They are crossed at 250 Hz and 2000 kHz. I think that the 15" are JAMO design (made by who?). The best alternative I was able to find was the BD15 bass driver (www.bd-design.nl).

Very nice but a little pricey (1600-1700 € for two pairs!).
I want to know if they are other alternative to such drivers: good sensitivity,light membrane,... Beyma perhaps? Or the future Peerless SLS 400 SWR (830867) ?

Im thinking along the same lines, the drivers used as far as I can tell are the Peereless you mentioned, they are listed as being available in Jan 06 at Madisound. Well see how much they go for soon, Im wating on a reply from them.

News just in,
Madisound now stock the Peereless drivers, approx $140 US Each.

Curious, it seems (for me) that the frame (and magnet?) of the Perless is different. But the price is very attactive. I hope that the frame will not be just a stamped piece of steel.

Try something from Ciare. Their 15.75Ndw2 for example has extremely low Rms, high Qms of just over 20!!! and high Cms. Look like hi-fi parametres in a PA driver

. I have just ordered four 15.75Ndw1's.

Ciare 15.75Ndw2

You can count on it having a pressed steel basket which is no major problem IMO.

Hi Tony,

To me it sure looks like it indeed is a peerless SLS 400 woofer

http://www.audiokit.it/ITAENG/Altopa...sDK/SLS400.htm

See the following link where in I speculate how the filtering is done to overcome the dipole drop. The series coil technique was originally used on the DALI skyline 2000 (and skyline 1000) dipole speakers as I recall it, where they used a high sensitivity cervin vega 15" respectively 12" woofer in a dipole configuration.

Opinions of the Jamo Reference R 909?
