hi Ali,
how are the amps coming along ?
Anthony,TD...

The amps are fine, I just need to give Nick the rest of the necessary to buy the chassis etc. All the iron is bought, which was the major expense- ironic really, given they are OTL amps!

Hopefully in the next couple of months...

Great!
look forward to seeing some picks of them, and to reading of your initial impressions when they are up and running.

Very very difficult with 3 way in fact I wouldn't even try it, but with two way it is very possible, and I have done it and so have Epos and some Royds got pretty close. Anyone is welcome to come around and listen. Just a single blocking capacitor on the tweeter, not a full range driver as bass mid, just doped and tailored with cabinet and positioning.

Richard, with all due respect I suspect the ES14s were measured and it was not just Robins 'ears' used to produce a speaker with no crossover.

Which brings us full circle back to the question that started the thread "Why do you need a crossover" and I will add be that passive or active. When with a bit of common sense and time you can do the same things mechanically.

Which indeed you can given the ability to design bespoke drivers and/or cabinets and measure the same.

How do you know, have you done it. Per usual you are talking out of your arse to try and get a response from me. Well done you succeeded.

Where has the reference to 'ears' gone, I'm confused.......

Sorry its here:-
