Are the same tweeter in the SL2 and NBL?

Posted by: Ulrich Hohn on 14 February 2003

My dealer says that in the SL2 the same tweeter are as in the NBL. I find that they sound very different. The SL2 has the type D2010/851100. It is without ferro fluid.
Scan-Speak manufactures also still the type D2010/851300.
It features ferro fluid in the air gap for higher power handling.

Does someone know, which tweeter are in the NBL and DBL?

Ulrich,

The tweeters in the NBL, DBL and SL2 are the same.

Richard,

...but, the Sl2 is presumably a lower sensitivity.

Early DBL tweeters used ferrofluid but, contrary to reputation, were famous for failing when the fluid was forced out of the magnetic gap (under the sort of heavy load that DBLs will take). New ones are f/f free.

cheers, Martin

"I'm fairly certain the tweeters themselves have identical sensitivity, around 90dB/w"

The NBL & DBL are 92 dB/w speakers.
