Large Advent tweeter replacement ideas

[guitarjunkie]

I have utility cabinet large advents; before I go the econowave route, are there recommendation for replacing the tweeters (and I guess accompanying crossover tweaks) that yield good results?
Thanks-
Mike

Morel MDT 29 or 30's are respectable tweeters. The 30's are a bit $$ but the 29's are better priced. I have used these as substitutes in several popular two way design with minimal xover tweaking. would also look at some Vifa & other Dayton types as well.

I replaced the tweeters in a pair of KLH-17s with Tang Band W3-593SF 3" full-rangers (supposedly 200-20,000 hz) and thought they were an improvement. The 17s had recently been recapped and resealed but the hi end was still a little lacking. If I were ambitious I'd probably re-jigger the crossovers, but they sound OK as is.

The W3-593SFs were about $20 a pair: I think they've been discontinued but there are other, similar, TB drivers available.

I'd start out looking at the dayton 1 1/8" tweets

basically look for something with a low resonant frequency to work with the low crossover point. I'd probably measure the original advent tweeter's DC resistance to get a ballpark feel for it's impedance, and adjust the xover accordingly.

I also have a beautiful pair of NLA's that I've been reluctant to Ewave not because I don't think they'll sound good but I like that they are original classics and want to keep them that way. That said I may some day acquire another pair and Ewave them, but in the mean time I wouldn't mind trying a "drop in" replacement for the fried eggs on my NLA's provided I wouldn't have to cut the baffle or change the crossover. Anyone know of such a tweet?

Are the stock tweeters bad????

Or are looking to improve them?

The Scan Speak Discovery has a rising top end...though the Original Advent Tweeter does not(drops off after 15khz) they do have a 12khz peak and I'll bet they sound similar in use:thmbsp:
