About 84 dB for normal sensitivity specifications. (Reference is SPL
at 1 metre for a nominal 1 Watt: 13 Watts is +11 dB ref 1 Watt so you
have to take 11 dB from the 95 dB to normalize it).

The brochure in the B&W archive gives 9.2 V RMS pink noise for 95 dB
SPL which translates to a sensitivity of about 85 dB at 2.83 V RMS
(the nominal 1 Watt/8 ohms).

I already know they are pretty sensitive ...

I have to say that 84 - 85 dB is not what I usually consider as sensitive
although the impedance curve is undoubtedly valve-friendly.


Yes, delete my earlier remark about sensitivity - substitute 'it doesn't
seem to matter much what speakers (84, 88, 89, 91.5 dB and a pair of horns)
I use or which amp (4wpc or 32 wpc). the volume setting always ends up at
the 10/11 o' clock mark!!
