Peerless version of: Scanspeak R2604/833000
This 25 mm dual ring radiator with centre phase plug has a low distortion response curve that extends effortlessly to above 40kHz. A double magnet system with tuned rear chamber yields an exceptionally low resonant frequency of just 589 Hz, which is a long way below the recommended crossover frequency - this tweeter is easy to use. The specially profiled 104mm diameter faceplate features recessed mounting holes for minimal reflection.

I was looking for something to pair with the Monacor SPH6M that I got from Willys HiFi as while back.
These tweeters are very very nice. Not the prettiest to look at (matter of opinion) but sonically superb. Very easy to work with crossover wise and because the the low FS you can get away with crossing these pretty low (1.2K) with a third order filter, this helps a lot with off axis response.
I ended up with probably one of the flattest responses I've seen for a while and a speaker that is very accurate (response / phase wise).
The top end these tweeters provide is clear, crisp and detailed without ever getting aggressive or fatiguing, although that could just be the way I 'voiced' them. Either way, I have to say I prefer these to the Scanspeak D2606 or the Vifa D26NC which have always been be my go to tweeters.
Pairing with the SPH6M you end up with what could be a pretty good studio monitor.
If anyone is looking to do a DIY build with a tweeter that is easy to work with, this could be it.
Note: It's great to have a UK supplier providing good quality parts rather than having to go 'across the pond' to source stuff.
Thank you Willy's Hi Fi.
Thanks for the fantastic 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!
