Hi Joe,
    CU a Raleigh next mo.?  (& maybe "Hampstead", do you know anything 
encouraging abt that one?)

    Only if it's centered between the filters.  It's possible one filter 
(the poor sounding one) has drifted a bit (and probably lost some of it's 
shape).   Try moving the osc./center freq. while your buddy listens to each 
SB.  If they can both be made to sound OK, and still have the same 
thruput/output, you're OK.  If the poor one still son't sound good, and teh 
output on that SB drops, you may need to replace that filter.
