Biwired-Dunlavy V- Bass reduced why?

Shadorne,

I am using Classe CA-400 in stereo mode. I agree this amp can drive any load.

Mr Dunlavy/reviewers in the past claimed/reported no audible change between single and biwiring and that the two terminals are mostly for bi-amping.

As i said in previous posts, I wanted to believe it was new speaker cables with V's, But with IV's using my well broken old cables biwired also showed relative reduction(actually you can think as removal of bass hump)in bass decible.

Is resonance or ringing you describe common phenomena? what are the indications that this happens other than lower bass db?

The Classe CA-400 with low output impedance/high damping factor (over 100 I would expect) should have no problem. It should sound great with either of your configurations.

It should not make a huge difference as you report (I trust Dunlavy's belief on this matter which is why I am just as puzzled as you are.)

As Herman suggested phase....is it possible somehow that you are wiring the woofers in opposite phase when switching to the biwired configuration?

If you suspect this then try reversing one wire pair to one of the speaker woofer bindposts (reverse only at one end and only on one speaker). See if teh bass comes in more strongly.

Here's a real dumb question - have you moved your speakers or your listening position, or both? If you have that could well be your problem. FWIW.

Nope!!
