One tweeter was dead and one almost inaudible on my 1997 B&W P4 speakers having connected the system after years of no use . My initial contact to describe the issues was through email for which I received a helpful response within a day. I followed up with a phone call and was talked through the likely problems with my old speakers . I was really impressed with how attentive and unrushed the conversation was with regard to a small potential order . Non B&W replacements would be available on the website within a week which I subsequently ordered . Delivery was quick and the tweeters work perfectly bringing the speakers back to full performance again . A fantastic and much appreciated experience with Willys Hi Fi.
Thanks for the review John!

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 !

Product as described, easy to cut & fit.
On reflection having now fitted the foam, I wish it was 15mm to 18mm or even 20mm thick. This is not a complaint. For a small speaker under 30cm high it’s perfect. For a larger speaker I feel a thicker sponge would hold its structure more pleasingly, its aesthetics, but important for the finished look.
I’ve been building my own home cinema as a complete DIY project and reached the stage where I needed some decent acoustic foam for my speaker panels (also DIY!) so I picked up 3 large sheets from here. They were sent quickly, packed well and moreover, are of excellent quality. With them being folded into the shipping box they were slightly creased but after leaving them out overnight on a flat surface, the creases fell out completely. They’re now in place and doing their job brilliantly. Cheers Willys Hifi!
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!
