Selecting replacement tweeters

[Ringwood]

Hi All,
I have got my hands on a pair of KEF Q55 speakers. This is a 3 way system. Both tweeters are blown. I have done a fair amount of research on line and from what I can see, these tweeters are delicate and go quite often. They are concentric mounted in the center of the midrange speaker. The only one I can find is a replacement part from KEF for about $100/pr.

I am wondering if it would be better to replace these with a cabinet mounted tweeter that would be more robust. The tweeters are 4 ohm
Any thoughts?

These are the specs for the KEFQ55:

System type: 2½-way, floor standing
Enclosure type: Reflex
Dimensions (H x W x D): 852 x 207 x 276mm (33.6 x 8.2 x 10.9 inches)
Weight: 13kg (29 lbs)
Nominal impedance: 8 ohms
Power Handling: 150W
Frequency response: 40Hz to 20kHz +/-3.0dB (-6dB at 37Hz)
Sensitivity: 91dB at 1m for 2.83V
Maximum output: 112dB
Finish: Black Ash, Mahogany, Video Grey
System: SP3317
Drive units: B160 Bass unit (SP1395), B160 Uni-Q (SP1449) [NT19 tweeter (SP1446)]
Crossover network: SP2338
Thanks.

Before buying anything different or Chinese you can try... "What to do list":

0. Kef replacement parts (originals drivers usually sell in matching pairs.)
1. Sending it to repair shop
2. Buying it from Kef Classic forums
3. Ebay.

Eventually a different type of driver or upgrade will make you spend more money in a new pair of drivers and different new designed and personalized crossovers. So this is many times the DIY route and might take a long time to have the speakers ready (?!) and tested, if not like a new pair of speakers professionally measured. 😎

Hi. It may not be necessary to replace these tweeters as it is sometimes possible to repair.
I'm no electrician and posess basic DIY soldering skills but repaired mine. It's a little fiddly but if you are going to throw them anyway what harm can it do to try?

I have now posted a video on you tube showing the removal, repair and replacement of these tweeters.

I realise this is probably a dead post, but just wanted to confirm that it is indeed possible to repair these tweeters, I have just done so too!
