Are there any good replacements for the 035Ti in the JBL L100T? I still have the ones that came out and have bought those $69.00 knockoffs ( which sound pretty good) I don't really want to buy
another pair of 035ti that is decades old and will or needs repair. Wondering if there is anything out there today that would fit the bill, don't care if it is textile dome or what not.
In fact I would prefer not going back with a Titanium tweeter...;Many thanks

Lots! 🙂 But the problem is mating it correctly with the mid range. Audio Heritage may be a better place for you to ask.
Your best bet would be to stick with the knock offs. At least they were made to be replacements. Or you could check on eBay for used tweeters. Any other tweeter from Scanspeak, SEAS, or Peerless MIGHT work, or they may need a crossover modification to function properly. Are you able to handle that?

By update, do you mean replacing capacitors and resistors? A new tweeter likely will require a partial re-design of the crossover.
rewind the coils to precise values and replace the signal path caps with T3 values in Poly. Replace a resistor or two to balance out the load
Looks like I just stay with these knockoffs or fine someone to repair the 035Ti's
JBL L100T - Manual - 3-Way Loudspeaker System - HiFi Engine
This is a 12" 3-way with a cone Mid and apparently a Dome Tweeter.
25mm Titanium Dome Tweeter
Mid/High crossover at 4500hz.
Sensitivity = 91db
The entire speaker is rated at 8 ohms.
Factors to consider -
- New Tweeter must fit available space on the baffle.
- New Tweeter must be of similar Sensitivity or higher.
- New Tweeter must functionally cossover at 4500hz. That's not going to be a problem though.
- New Tweeter must be of the same Impedance.
Likely the Tweeter is padded down (level reduced) to match the Bass/Mid, you will have to balance the output by adjusting the L-Pad Resistors or you will have to add a variable L-Pad.
Then to the critical question - How much do you want to spend?
I would say the working range is about $25 up to about $1000. Were are you on that spectrum?
You could consider buying some used JBL-L100T and scavenging parts, though tweeters are often the failure point in speakers. But you might find one with failed bass drivers (typically deteriorating surrounds) and be able to scavenge the Tweeters.
Of course, then you have to Boxes that you have to decide what to do with. You could use them to build some low cost speakers, and sell them. Or you could just throw the remaining parts in the trash. That's up to you.
Or you could just bite the bullet and buy something from the new JBL Line of Big-Box Speakers -
JBL - 4307 Bookshelf Speakers (Pair)
JBL - 4312G Bookshelf Speakers (Pair)
JBL - 4319 Bookshelf Speakers (Pair)
JBL - 4429 Bookshelf Speakers (Pair)
I would dearly love to have a pair of the JBL 4429.
Just a few thoughts.

In my JBL 18Ti I replaced with Seas 27TBC/G in a WD 300 Monacor waveguard.
I think it was better than with the original tweeter.

Here is a picture.
The original hole is 12cm, no tweeter is so big.
The WG300 is 16cm, needed to cut off the bottom.
The crossover is good, maybe you can change R4 to 2,2Ohm, if the tweeter is too loud. (and use good MKP for the highs - for example Jantzen Superior-Z)
I like more mids, so the C3 cap should be bigger, 33uF and should be good MKP also (Clarity PX or ESA - cheap and good)
More vocals and better stage will come with the good capacitor.

Sandor
