Vifa Peerless XT25BG60-04 Tweeter

Vifa / Peerless XT25BG60-04 25mm Ring Radiator, dual magnet, 4Ω.


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.

A full datasheet can be downloaded from the bottom of this page.

Great Tweeter...very under rated.

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 !
