    2,2A or 2B?
    A 2 and a 2A. The issue doesn't really matter now as we've determined the issue. See above.
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

    ... and 7.5ohm Resistor inline with those woofers via 2nd order setup.
    Inline as in series with the woofer? or in shunt across the voicecoil?If in series with a woofer that would be highly unusual practice.For tweeter attenuation yes woofer no.
    No Polk loudspeakers work with only an inductor, period. NO first orders.
    Then the schem. for the SDA 2 is also incorrect.It is essentially identical to the one for the 1A with the exception of the coils value doubling to account for the incresed impedance of using the single 6501 for bass only duties(vs the dual 6501's in the 1A.)

    Thank you for the help as well FTGV and I'm already aware of the other schematic.
