I think your Bolero speakers would sound good any way they are hooked up!
Can I hook up speakers without using the ground?
I accidentally hooked up some speakers using the 4 0hm tap for the positive run but accidentally connected the return to the 4 ohm tap instead of the common/ground.
I didn't damage anything but I didn't leave it connected that way long. It had some interesting sonic effects that I did not take the time to explore out of caution. The hook up reminds me somewhat of the hook up you used with the old David Hafler design for pseudo quad set ups rear speakers.
The amp is a Mesa Barron dual mono. Speakers are 3 way dynamics with very expensive tweeters ergo my caution.
Is there any short range or long range risk doing this?

Al, Thanks for your comments. This amp has an adjustable feedback loop and its effect on the sound when I had it mis-connected was huge. That's how I knew something was wrong, apart from a tonal balance shift towards more of everything except highs. It was interesting though (after I had correctly terminated the speakers) to hear what my electronics from the late 80's and early 90's sounded like with my Bolero's. Not bad! Grannyring is right. :-) |

Probably the mismatched loading was resulting in abnormal amounts of distortion, which would have been partially corrected by feedback, to an increasing degree as the amount of feedback was increased. Also, the change in the transformer turns ratio that was being used would have reduced the output impedance of the amplifier, causing a more solid state-like tonal balance. Given the impedance curve of your speakers, shown at the bottom of this page, that would mean a de-emphasis of everything above around 2 kHz. Best regards, -- Al |
