Mission 753 tweeter
Suppied as pairs on an exchange basis - we require your unmodified plastic faceplates.
Please contact us if you need more information.
High quality treble replacements for the obsolete 53-HFLM2 as found in the popular Mission 753 floorstanding loudspeakers. Features include light ferrofluid cooling, critically damped hand treated domes, neodymium magnets + heatsinks for substantial power handling. Assembled and close pair matched in our UK workshop.
Excellent, smooth sound quality, cures the inherent 'tizzyness' of the original tweeter.
Prewired with the correct colour coding for easy connection. This product is exclusive to Willys-Hifi Ltd.
We also supply tweeters for the 751 / 752 standard and Freedom models.
How does this work ?
Purchasing these tweeters generates a unique job number - you will receive an email with instructions of what we require from the old tweeters and our workshop address.

Id had these speakers for a couple of years. I got the S/H and already the tweeters weren't working when purchased. Played them for and while but parked them up hoping one day to organise tweeters. Well that day finally came and i am blown away. Easily better than my Jamo 507A's and TDL RTL 3's. I drive them with an adcom 5300 and nad as pre amp. I am in New Zealand. The turn around time was within 2 weeks. Saving up for the crossover upgrade.
Thanks for the review Michael !

I wasn't sure what to expect but the new replacement tweeters are very pleasing to listen to. There is no harshness and they seemed to provide a very airy and broad soundstage. These along with the crossover upgrades has provided a whole new appreciation for my speakers. Fast service with quick turn around time. Highly recommend!
Thanks for the review Vaughn !

Excellent upgrade, works perfectly with the speakers it's just soldier and play, they takeaway the over intensity of the original tweeters.
Thanks for the review Matthew !

Excellent service from Willys-Hifi. Caroline was very helpful and patient when answering my queries. Please be aware that some soldering is required when connecting the tweeters. Something I haven't done since I was at school over 40 years ago! They do sound good though, listening to Smoke on the Water as I write , wow 😆
Thanks for the review Karl. Deep Purple - good choice !

The crossover was constructed well, I just need to figure out the best way to attach it to my Kef Concertos as they are bigger than the ones supplied by Kef that are mounted on the front of the baffle board.
Very nice deep bass look amazing with my custom made speaker
Great speedy delivery and very easy to fit. The plastic in my drivers had perished and they had suffered one too many parties! No need to make any adjustments (someone above did suggest that). I just screwed them in and the foam compressed into place. Before and after below (before I changed speaker number 2). Thank you!
Thanks you very much for the kit. I found back my kelidh after nearly 27 years. The filter were really dead and one tweeter damaged. Very happy to decide to repair/ upgrade rather than change. I found back tone and stereo stage like in the old days probably even better.
I didn't know soldering material was so important thanks for providing some.
Quite easy to recap filter and change tweeters.
Also wanted to thank you for this little note hand writen in French just for me. Very nice attention to see.
Next step is the next question do I change first the drivers with the monacor as I ve lost dust caps but they still work properly or do I change my old arcam alpha 8. Is there really something to gain moving to an newer arcam sa10 or Radia a5? Are newer amplifier much better than the old days one?
In addition to my post from 17/11/2025, here is some information on the final status of the project: Saving the Mission 752 loudspeakers.
Once it was certain that it would be possible to revise the loudspeakers (thanks to Willy), the desire to also replace the low-midrange drivers and convert the crossover to a high-quality version quickly arose. I was fortunate enough to be able to purchase two Burmester 949 MKII midrange drivers from Audax to replace the existing low-midrange drivers (52LFHDA – still available and can be sold). They are practically identical in design, but significantly more refined and powerful. Revising the crossover proved somewhat more difficult because the values of the coils were not printed on them. However, they can be determined by measuring the originals. Mundorf resistors, coils and capacitors of the two highest quality grades were installed. These are not exactly cheap, but once the speaker is finished, the difference is clearly audible. The crossover was also modified slightly. A shunt was integrated into the high-frequency branch. Following a tip in a forum, the crossovers were also moved to the outside. They are currently still on the speaker without a housing. The metal housing provides perfect shielding. As the Willys tweeters are very efficient, they were ‘damped’ slightly. The final cost of the conversion was approximately £600. In return, the speakers now perform at a level that far exceeds their original condition. An exciting project that was only made possible by Willys – thanks to Caroline & Will ❣️
