I have to replace the drive units in my Clements Reference 1 loudspeakers, one of which accidentally got burnt out. The Monacor 135mm units appear to be very similar in mechanical fit to the existing unit, but there are a number of variants available. The best available (I'm assuming) are the SPH-135C (carbon fibre cone) and the SPH-135KEP (Kevlar cone).
Details of the SPH-135C which is listed as a bass-midrange are here
while details of the SPH-135KEP which is listed as a midrange are listed here
There are some opinions on these drives here
And a useful table here comparing the drives here
To my untrained eye their specs are very similar, except for the cone material (carbon fibre/kevlar) and the fact that the Kevlar model has a phase plug.
Which should I choose?
I'd be interested in hearing from anyone who has compared these units by listening to them.
Regards,
Neil (J Mackie).
