Dunlavy vs Coincident

Sean, how did you make out with the Seas drivers you got from the Coincidents? Did you graft them into a new project? I have been meaning to ask you, but this thread put it back in my memory. Were you able to contact Israel in regards to the differences from an off the shelf Seas driver(if any), and crossover design? Is he running these mids flat out, or with crossover components? His newer designs feature high impedence(10 - 14 ohms), and I was wondering if he was running the drivers in series, in order to double it(from 6 - 8 ohms). Any information you are kind enough to pass on would be appreciated. Thank you.

Thanks for the update Sean! I am regret that Israel did not respond back. As I said, I do feel the drivers are probably wired in series(via their advertised impedence). After you perform your measurements, for fun you might want to try wiring them in series, and running them flat out(no crossover components in the circuits). Do some analysis of this configuration, and proceed from there. I have also migrated to the simpler is better philosophy in terms of crossover design. I feel it lets more of the soul of the music through, in addition to being the most benign load a dynamic driver can present to an amplifier. The success and great sound of Coincident is living proof to me that others also agree. I do feel that a capacitor on the tweeter leg is necessary. Especially, if the speaker will ever see a good deal of power, which we cannot ever discount during the design phase. As you have four drivers, do you feel more inclined to use a D'Appolito configuration, or go with both midranges below the tweeter? From my experience, Seas drivers offer a very fast sound. Perhaps their strongest of attributes? It makes sense to design a lively speaker around them, to show them in their best light. As they say, the midrange is 85% of the speaker. Woofers lagging behind would not integrate well into a holistic loudspeaker, in my opinion. Just one man's opinion. However you proceed, and whatever you do, GOOD LUCK! Again, thanks so much.
