It's different enough. The 194s and 198s have different impedance and frequency response. The 194s have a relatively flat response, while the 198's response drops as the frequency increases. A contour circuit is needed on single tweeter models like the CRS+/2B and all the Monitors. The more elaborate crossovers, with multiple tweeters required even more tweaking to get the progressive point source right. Don't let small changes in resistor, inductor, capacitor values fool you. A tremendous amount of re-design work, computer modeling, and extensive listening tests were done by some pretty smart fellas back in the day

Dave,

Thanks for the specifics and detail. The speakers sound good now, but what do I know, I haven't heard either of the rebuilt 2.3 versions as a comparison.

Ok, then the next question is when I get you to rebuild my crossovers, how difficult or more expensive, is it to do just the tweeter circuit for the "TL" version, and do the driver circuits as "standard" 2.3? I don't particularly want to change all the drivers out and do a complete TL conversion. Or should the entire crossover circuit be regarded as a complete integrated unit? Ie., you can't tweak just the tweeter circuit without effecting the whole speaker. (I suspect I just answered my own question?)

Just trying to work with what I've got, 6 of the 194s would be ~ $350. Granted I should be able to get some return on my existing 198s.

Cheers!
