I'm using a full range driver plus 2 bass drivers in OB, biamped thro' an active Xover.
When I play my stuff through my active Xover, I have the Xover attenuation turned down so that the volume control on my pre-amp gives a useful range ... max vol at about 11 o'clock...
This arvo, after the storm, I have experimented running the fullrange speaker full range (novel huh - dunno why I haven't done it before ) and I gotta say it doesn't sound all bad...
OK, sounds like a good idea ... only the bass amp running thro' the Xover, and the full range straight from the other amp... problem being that max listening vol comes in at just under 9 o'clock ... not much room for adjustments
How can I attenuate this so I can have my vol control a bit more spread out?
I don't want to buy a new amp ... and I don't want to fork out much dosh...
Oh, the source is a CD player - no output control.

Hi,
sounds like you need to add an attenuator of about -6db or possibly -12db before the straight through amp to the full ranger.
4k7 line resistor and 4k7 grounding resistor will cut about 6db. but the source impedance will be high and needs to be right at the amp input terminals (it will fit inside the RCA plug).
for -12db try 7k5 line and 2k4 grounding resistors.
The cuts will be slightly higher (less volume) due to the loading from the input impedance of the power amp.
