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
Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
I’m no expert when it comes to speakers, but after some research (and a strong recommendation from ChatGPT), I went with the SB Acoustics SB65WBAC25-4 as a reference full-range speaker in this size range.
Having now tested them, I can confidently say they’re probably the best speakers I’ve ever owned. The clarity is outstanding—every detail comes through with incredible precision. The bass is surprisingly full and punchy for a speaker this size, and they handle power impressively well. For anyone looking for a high-performance compact full-range driver, these are hard to beat.
Item as described and arrived quickly - and did the job. However, I suggested that anyone replacing speaker foam makes sure they have a very large pair of sharp dressmaking scissors as it was not easy cutting to size without producing a ragged edge (which I managed to hide short of a close inspection)!
