I came across some info that after many years these old B&W P4's tweeters degrade. As I grew older, (with reduced hearing of course), I never noticed this gradually deterioration over the years. So I bought the replacement tweeters from Willy's which was picked up just a few days later in Norway. They were mounted in 30 minutes,.. and what a change! My HiFi sounds as a new set. Thanks!
Thanks for the review Morten !

Tweeter has been shipped very quickly and is working perfectly now. One point to mention is, that it did not fully fit mechanically as replacement as it was announced, had to rework mounting part slightly
Thanks for the review !

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.
This made a massive difference to my 30 year old Linn Keilidh speakers, giving them a new lease of life.
Willy's is an awesome serivce. I needed a 4" midrange replacement that is a drop in exact fit for the IMF TLS50. If you are ordering from the USA, the Monacor MSH-115, 4" is your best option. I live in Pennsylvania and it only took 5 days from the time I ordered to be delivered from the UK. Royal Mail provides tracking. I dropped in cab and was fired up shortly on the same day. Sounds great. Totally worth buying these instead of rebuilding old speakers.
Willys saved my Mission 752 speakers. The tweeters were defective. The original tweeters are no longer available, and it would have been a shame to throw away these really good speakers. I came across Willys by chance in a chat room. Even there, the company and especially the tweeters were highly praised. I contacted Willys and received a very friendly response. Ordering the speakers went smoothly. However, shipping to and from the UK is a real adventure due to ****. It is expensive, cumbersome and no fun for either side. The tweeters arrived two weeks later and were of course installed immediately. The result is truly impressive. Airy, clear highs (previously a weakness of the 752, which tended to ‘hiss’) and a sound image that really thrills me. The ‘old’ Mission 752s seem to me as if they have been swimming in a fountain of youth. Thank you for the good service and the high-quality tweeters. ❣️❣️❣️

What a business, such a personal service , superb communication , and speed of delivery.
Bought a matched pair of Hiquphon OW1-92 Tweeters for my ancient Linn Kan’s Mk11.
WOW back to life , if not better , the main difference I hear , is more life, output, depth from the tweeter without taking away what I love about the Kans.
Will order a second set very soon for my other pair.
Thanks Will , and Happy Birthday.

Loved the extra touch , gaskets, solder and screws.
