I bought a pair of Tannoy Monitor Gold in the early seventies and a year
later a pair of JBL 4311. I liked the bass and warm sound of the Tannoys
and the crispness of the JBL. I figured that I would use both pairs to get
the best of both worlds. It sounded very different than what I was hoping
for. Very disappointing sound. I tried and tried to force my ears to "love"
that sound. No avail. Then 6 months later I discovered that Tannoy and JBL
did not have the same polarity standards. One would push while the other
one pulled. I had heard of push pull circuits, but this was ridiculous :-)
Reversing the polarity more or less gave me what I was hoping for from the
start.
