Can you increase the efficiency of vintage speakers?


Hello to all...

I have a pair of JBL L25 Prima speakers which have an efficiency of 73 - and I am wondering if I could increase the efficiency of them by rewiring them: I am now powering them with a Parasound HCA-750a ( high current 75w/c/8ohms) power amp, using the pots on the back of the amp...

I'm assuming that rewiring them would change their sound abit as well: has anyone ever experimented with this approach?

Thanks for your input... BTW: Miller carbon pointed out to me that the speakers are much more efficient than I was led to believe.
Presently: they are only about 12" away from the walls and sound amazing!

...enjoying these speakers immensely: presently using solid core 14g copper wire twisted together (homemade) as speaker cables - would changing this to 16g "modify"/change the sound?

Sorry - but I am confused by your comment... Are you word-waring with millercarbon for reason?

And please explain your "+1 MC" note - it's meaning is obtuse to me within the context of this forum and my question...
