Default Oo-er, missus! Wot a huge pair.....

.....of speakers.

(OK, wot were *you* thinking of ??)

See http://www.apah69.dsl.pipex.com/keit...w/speakers.jpg

I'm auditioning a pair of B&W DM2As and I have to say I'm *very* impressed.
Talk about size and weight - my Ruark floorstanders weigh 28 kg eack, these
muthas (standmounters, mind) only weigh 22.2 kg each.....!!!

Does anybody know anything about these? Were/are they rated? (I gather they
are from about 1975, but as Michael Caine once so famously stated - they're
in lovely condition...)

I've got the manual which is full of techie stuff like a Buel & Kjaer
readout (right hand speaker only) and 'polar response' charts but it doesn't
state a straightforward Sensitivity Figure other than to say:

"Sensitivity - 13 watts into nominal 8 ohm impedance required to produce a
sound pressure level of 95 dB at one metre at 400 Hz."

What does this translate into?

I already know they are pretty sensitive because they are *well large* at a
relatively low volume setting on a 4 watt amp despite a recommended rating
of 25 to 60 wpc! (Book also says impedance never drops below 7 or rises
above 22 ohms, 20 Hz - 20 kHz**)


**which is nice! :-)
