Morel ST 1308 Tweeter

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.

Excellent customer service
Quick dispatch
Swapped out the 30 yr old AlCap capacitors for the Audyn Q4 on Wills recommendation (along with a ferrofluid change). What a difference, added so much more definition and clarity. Very impressed. Audyns are a fair bit bigger size wise but fitted easily enough on the board and the access aperture on the TDL Studio 1's.
Good quality, fast postage, perfect! Thanks
Can fault the service and you always seem to have what others don’t, this can be critical when your hobby involves restoring vintage hifi .
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. 👍
