Phasecorrect- I will be looking into that. If we were to change the tweeter, the circuit mods may be ones that you can't get your hands in to perform (nor could we). The woofer stays the same.
One would have to knock out the old crossover circuit (via a block and hammer), from which we could salvage maybe $25 of parts, with a half-hour to strip those out, and a few bucks credit for getting the old tweeters back. Two new circuits with tested, matched tweeters would be ~the price differential to the new speaker. Plus a fair amount of install work at your end. And it still wouldn't have all the improvements.
At the moment, it would seem selling `em to a buddy and getting the new ones would be the best way to have a comprehensive upgrade. But I will look into it.
Pete- congrats on the new baby! You'll be a great dad.
You are entirely right about listening "habits". We do what we need to do. Remember, the middle-ear bones are bridged by a small muscle that contracts to protect against loud sounds. This changes much of your hearing.
Listen loud and long with some good wine, and the muscle stays locked up, then relaxes some, as your mind eventually says "nothing here to worry about, ok?" But it still never relaxes completely.
During that contracted phase (like after a concert), several things happen:
Your threshold of hearing has been raised (friends need to yell at you),
the tone balance changes (for less bass and highs),
dynamic inflections are not as strong (less subtleties, and "big" changes need to be "bigger"),
the body takes over "feeling" the bass, because you are vibrating different parts of it more and more,
the pitch of the song rises (for psychoacoustic and/or mechanical/biological reasons).
So you are shocked the next day. Just don't do that every evening, and chances are your hearing won't suffer too much beyond what you lose with age, and by living in a city instead of in the country, in my experience.
But if you blow things up, we have parts. So proceed onwards, Mr. Whitley. Dad. Mr. Mom?
Just don't expose the little one to even a moderately loud TV program for extended periods (like an hour) if you can avoid it, ok? But you will expose him/her to music, right?
Have a good weekend y`all!
Best,
Roy
