Started yesterday. Swapped out the rotted-surround, full-range, original speakers for a relatively new pair from a JVC Kaboom. Old speakers are 6 oms , 20 watt max. while the "new" ones are 4oms 25 watt max.
Sure is sounding goooooood, for no tweeters. Still gotta do some calculations before I turn 'em up, but so far, so good. I don't really want them drawing 25 watts at the lower impedance. Don't want the amp to be required to try to produce more current than it was designed to handle.
Working with nominal impedance and full range speakers I believe gives me speakers that are wired in series, one per channel. Without an RCL meter to give me capacitance or inductance I don't have an easy way to figure out Xc or Xl to get a proper calculation for Z. I believe these speakers should handle the watts but I'll be damned if I can figure out how to prove it ( or remember how is more like it.) I seem to remember that series R is actually pretty close to series Z.
Full range speakers would be designed to work over a wider frequency spectrum than usual, which gives me the impression that everything should be ok at low volume, but I really want to turn it up without ruining a pair of speakers that, while they are extras, are perfect drop in fits.
Help is always appreciated, especially from this particular peanut gallery...
Is it just me or does Wikipedia get harder to read the older I get?
