DIRECTLY REPLACES SEAS 19TFF1 / H0737-08
The D19TD-05-08 is possibly the most popular 19mm soft dome of all time. Found in a huge amount of respected and award winning models from manufacturers such as Mission, Rogers, Heybrook, JPW AP2 and AP3, Monitor Audio and countless others, this relatively inexpensive tweeter is a very capable performer hence its long term popularity from the 1980s onwards. An excellent replacement for the Celestion HF2000 & HF2001 (8 ohm versions) found in various Ditton models.
The smooth response and excellent dispersion sets the bench mark at this price point.

I was so pleased to find these replacement tweeters for my much loved Snell K speakers. After 30 years of great performance it was time to replace both tweeters after a sudden power surge resulted in a muffled sound. On inspection I also noticed the foam surrounds on the woofers had deteriorated. So I spoke to Will and purchased a pair of Scanspeak woofers made in Denmark, a perfect match for the originals. Will was really helpful and the new speakers arrived by courier within a couple of days. They sound brilliant. Great to have Snells performing as new! I am so pleased.
I cannot recommend Willy’s Hifi highly enough. Informative, efficient and reasonably priced! Old speakers will never die!
Thankyou for your review !

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 ❣️
