Beetle - No, No I didn’t mean it!JA - Ray is a good idea.All - I continued my comparisons re cabling and noticed a deep bass rumble / congestion with the C arrangement: ++ and --, taped together for close parallel run. Rather than side by side, I put each speaker individually against the corner fill and compared measurements. C had a 10dB rise below 30Hz to the cut-off at 10Hz compared to B, which continued its normal bass rolloff. I confirmed with listening in that corner position. Now, a bass reflex cabinet is rolling off at 24db/octave. There must be powerful resonant mojo in that cable configuration to produce that much deep bass. Anyhow, the B - separated runs - sounds cleaner and more articulate.I’ll repeat this morning and scratch my head.
