    I just got in and checked the wiring for the right speaker. All MW's are connected just as the schematic says. I will keep on brainstorming.

    Blade/Blade SRS-2, 3rd generation? If so, verify the ground leads on the stereo and dimensional woofers are correct. Some had Black/Green for the Stereo Harnesses, and Blue/Green for the Dimensional harnesses. Some had Black/White for stereo and Blue/White for Dimensional. Some even had Black/White for Stereo, and Blue/Green for Dimensional. The point is, the grounds or neutrals are different for each harness. If they're mixed up for some reason, the crossovers won't work properly.

    I have checked these and they seem to be correct. The bottom dimensional drivers (not the donut drivers) on both speakers have blue/blue going to the + signal and green/green to the -, assuming that the red dot means positive. I can't tell from the schematic if this is correct or not. the schematic I looked at showed the wires pointing one way on the left speaker and another on the right with no + or- signs. Either way, I have them wired identically in the manner stated above.

    When I turn the balance all the way to either direction, the stereo drivers are still producing sound, which seems odd to me.

    I know these SDA's are unique in that they are the only ones with sub bass drivers on the dimensional side who carry the stereo signal, this seems to make it a little harder for me to figure out.

    My quote only applies to the 3rd gen SRS-2s, nothing to do with your 2.3s.

    Okay good to know, I know there are so many variables here. I just have to figure out whats going on with the right channel. My only thought at this point is the crossovers need to be redone, which I was going to have done at some point anyway.

    I just tried it without the interconnect and the right channel does the same exact thing either way. Could there be something wrong with the crossovers?

    SDA interconnect cable disconnected, and you have sound from the opposite-channel speaker with the balance knob all the way to the other side?

    Balance pot needs cleaning/adjusting/replacement. Or the amplifier has a crosstalk/channel separation problem. Either way, not a speaker problem.

    interesting, I guess I never thought of that. I am running an adcom GFP 750 and a B&K Ref 200.2.

    The reason I thought is was the speaker is because I have used these components with other SDAs and never had this type of problem. The other speakers were a pair of modded 1Cs, modded 1.2TL and stock SRS 2s blade/blade.

    Nah, you've got a problem with that pair of speakers.
