Have you ever wondered what it looks like inside a(real)KEF Q100 driver?

[Remlab]

Damaged the tweeter, so the company sent me a new driver, which I will use in my next speaker design..

No copper on either pole piece.
The tangerine waveguide is metalized plastic on the front side. Cool to see it from behind.

Very neat. Do you buy the drivers from KEF directly? I'm just curious in case I ever need a replacement for mine.

Yes, but you have to show the purchase receipt and serial # before they will sell you one, so if you still have it, keep it.

The driver weighs as much as the cabinet it's mounted in🙂

How much would they cost for two of those drivers?

 

[Remlab]

Good question. Luckily, mine was still under warranty, but Speaker Exchange sold(sells?) them for around $112 a piece,so I imagine it would be around that amount

This is being sold by a private party for considerably more. Gulp!

Thanks for this Remlab.

I also had to prove to them with a photograph that the tweeter was damaged. There is very little clearance between the tangerine waveguide element and the tweeter diaphragm, and apparently the tweeter diaphragm became dented by coming in contact with it. This damage showed up in measurements as a large resonant peak at 10khz. I wonder how often this actually happens and goes unnoticed, especially in the inexpensive models with low element crossovers.

I always wanted to get a good look at the rubber decoupler at the top of the voice coil former. I imagine that getting it right has been a delicate and constantly evolving process.
