I did more research: The in wall Boston Acoustics are 8 ohm. Yes the AB is in series. When the switch is on A+B and all 4 speakers are hooked up, the A (Klipsch) speakers are barely audible. When I remove the B speakers, the A speakers totally cut out. I guess that just confirms the series setup. More details on the in wall speakers are below. If the impedence difference is the problem, is there a way to hook up some sort of speaker switch to the inputs to level this out? Or do I need a receiver with AB in parallel? Details: » 3/4" dome tweeter » 5-1/4" woofer » handles up to 90 watts » frequency response 75-20,000 Hz (±3dB) » sensitivity 90 dB » 8-ohm impedance » paintable speaker grilles » cutout dimensions: 6-3/4" diameter » mounting depth: 3-1/8" » warranty: 5 years

oops they are the KG 2.5s -- had them forever (and love them). Yes, running these out of the speaker output of the receiver as intended. Receiver is Sony STR-D711.

No, this is a surround receiver. The A and B circuits are completely separate from the Center and Rear speaker inputs. I can toggle these surround speakers with the (surround) Sound Field on/off button. In either case, the front R and L have these symptoms.

Yes. The A circuit works great on A. The B circuit works great on B. The B circuit also works great on A+B. Its the A speakers when on A+B. They do work buy barely. Not sure if it helps to mention that the little sound that does come from the Klipsch A speakers when on A+B, is very subdued. I have to crank up the volume to hear it and it sounds muffled with lots of reverb. I appreciate you staying w/me on this problem!

Yes, the D711 doesn't have the impedence switch. The D911 does. The manual says the AB setup is run in parallel if that impacts any potential solution.... Any ideas for a remedy?

No, my receiver doesn't have an impedence switch. What is a bridge jumper and is it something I can address, or are we talking new receiver? Thx for the help!

I added a set of speakers in the kitchen on the "B" circuit to my Sony receiver (STR-D711). My Klipsch 2.1 satellite speakers (on "A") go nearly comletely quiet when I use the A+B setting, and the tiny in wall Boston Acoustics (on "B") are loud. Is impedence playing a role here?? I have talked to many folks, none of whom seem to have an answer. Help me Obiwan, you're my only hope!
