130mm offset faceplate version.
PRICED AS A MATCHED PAIR.
The Morel ST 1308 is a high-end 28mm soft dome tweeter from the Supreme range with an offset 130mm aluminium faceplate. This innovative drive unit features a short voice coil operating in a long magnetic gap - linear operation is maintained throughout the bandwidth even at high output levels as the coil assembly never strays from the area of peak magnetic flux (this mode of operation is often referred to as 'underhung'). The voice coil is wound with Hexatech Aluminium wire (Hexagonal section, zero air gap) and is cooled by ferrofluid. The dome assembly is hand coated with Acuflex damping compound and is field replaceable. The critically tuned and damped rear chamber yields a low resonant frequency of just 680 Hz.
Power handling is excellent at 220w nominal, 1000w peak.
As can be seen from the datasheet, the ST 1308 has an incredibly smooth response; the critical 3kHz-17kHz band is held within 2dB limits.

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)!
