I suspect I probably have heard the Diapson's at some point:
6moons have a review here (Adamante MkIII) http://www.6moons.com/audioreviews/diapason/adamante.html.
I see they claim direct connection, but a quick look at the review pics show the X-over and it clearly has a cap, a resistor and an inductor.
are you talking about the darius?
I thought it was produced in-house.
Yes, the one that sat in the tubular metal stand.
Just a point on the ES14 and other models with directly connected bass drivers.
They aren't crossover-less. Inductance within the driver motor rolls off the top end in exactly the same way as using an external inductor coil. If you examine the circuit formed by amp output, cable, woofer in terms of LCR you find the same properties forming the same filters.
The ES14 method should certainly be better and the main driver is excellent, but if you correctly view the crossover as a filter, it still has one.
Robin Marshall likes to talk down his design work in the ES14's, he's very self depricating, yet here we all are talking about them still. They aren't perfect but they still do some things better than any other speaker.
Really? Which things?
Nobody as I know ever got to the source of bass driver. It has Celestion, Richard Allan and Spendor looks all over it (anorak off now).
I thought it was produced in-house.
i'd like to know too....i had a set but kind of grew out of them although they were good.
hi rob....r.e. darius... you do know it went through several crossover series....i don't ever remember a production one with no bass crossover.....i used them active when i had mine.
