I was specifically looking for the db rating of their version of the P12Q and P12R.
I am trying to find a decent speaker which is inefficient for recording at home to pair with an 18-20 watt Marshall Head so 96db and below would be good?
The Webers are reputed
to be a "little" more sensitive and a "little" brighter than a Jensen P12Q. The Jensen is rated at 95 dB SPL @ 1 watt, so the Weber is probably a couple of dB higher (maybe 96 or 97?).
If that's still too sensitive you can pad it down by 10.5 dB with a power "L" pad. An 8 ohm series resistor
with a 2 ohm parallel resistor
(with an 8 ohm speaker) will drop the sensitivity by 10.5 dB.
The 20 W. amp is going to saturate before the Weber speaker anyway.
With the pad, instead of the 108-110 dB SPL you'd get at saturation, you should expect to be at about 100dB SPL with the resistor pad.
