Morel ST 728 Tweeter Black
Categories: 0.75 - 2" (19-50mm) Dome Tweeters Morel Tweeters
PRICED AS A MATCHED PAIR.
The Morel ST728 is a high-end 28mm soft dome tweeter from the Supreme range. An advanced design featuring many of Morels proprietary technologies engineered into a compact body of just 53mm (faceplate 72mm) - the diminutive dimensions in no way impact the sound quality which is on par with it's full size stable mates.
Features include an underhung Hexatech™ Aluminium voice coil, Neodymium flat pancake ring magnet, diecast alloy rear chamber & an IDR Aluminium faceplate. The dome assembly is hand coated with Acuflex damping compound and is field replaceable. Power handling is high at 120w.
As can be seen from the datasheet, the ST 728 has an incredibly smooth response; the critical 2kHz-10kHz band is held within 2.2 dB limits and the off axis response is excellent.
Available in Silver or Black, please select from the drop down menu above.

Excellent customer service
Quick dispatch
Excellent driver and superb service and advice from Willy's hi-fi. Would certainly recommend and I will definitely be using again. Super fast delivery and great prices
They offer great advice genuinely helpful and knowledgeable.
Excellent service.
Very happy with this replacement part, especially once id fitted it correctly!! Sounds great so know where to go when the other one fails. 👍
Just as expected. Works perfectly as a subwoofer @400Hz in a mono bi-amped active internet radio set up in my study. Thanks!
Bought a pair of these to replace the failing drivers in my 20 year old Alesis M1 Active Mk2s. They are physically a near perfect match for the cabinets and are a good match electrically for the amplifier, but sound better than the original drivers. The only slight complication is the original drivers use one 2.8mm and one 4.8mm spade terminal, so you need to change one of the connectors. These have given my old monitors (now my 'kitchen speakers') a whole new lease of life. Next step is to replace the rubber surrounds with a grille.
There is a detailed review of these drivers over on youtube: https://www.youtube.com/watch?v=NCb-rzCSK2s
Great service from Willys. They were dispatched straight away and arrived next day, very well packed.
I recently installed the Linn Keilidh active Tweeter Upgrade Kits from Willys Hifi. It works great! It took
1 month to get here snd had to pay an additional 90 euros in taxes and customs fees but it was well worth it!
