SPH-135KEP
The Monacor SPH-135KEP features a woven Kevlar cone and phase correction plug yielding a very wide and smooth usable bandwidth - the output to 7 kHz is remarkably flat. With a maximum linear excursion of 6.5mm this drive unit delivers an open, airy sound and is equally at home as a bass / midrange in small bookshelf designs or as a very fine dedicated midrange unit.

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.
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.
