I've had various Eminence coax including cast frame versions of 12"& 15" - there's tradeoffs

It was so long ago now I forgot I had bought the 10" version after selling the 15's. I had hoped the 10" would play better with the CD but it didn't. Ended up selling those too.

They would probably sound much better with one of the good Radian CD's, but I wasn't willing to invest that kind of money in "probably".

Sorry, this is all OT anyway.

Thanks for all the great measurements.

OK, much too high for a typical 15". Just because it's coincident doesn't mean one can ignore the basics of good speaker design.

OK, to my way of thinking/experience, an OB is the inverse of a horn/WG, so unless severely BW limited, it needs the same sort of attention to design detail which brings me back to what I postulated earlier WRT baffle size.

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.

FWIW, there was early on a cooperative reconfiguration of the XO by a builder and the system designers to ameliorate some of the issues in the mid-range, but all accounts it remains pretty much a love 'em or leave 'em sort of thing ( the same could be said for a lot of my own speaker builds )

The 2 occasions on which I've heard a pair of the SI15 with the budget compression driver and updated XO didn't make me a fan, but then I didn't much care for the HD Super12, which was widely acclaimed as well
Fate - something that people make up to try to explain how things worked out

It too was my feeling that the gap between 15 & tweeter made the Silver Iris a non-starter. The 15" also has A LOT of resonances.

But some people love them....

Thank you every one. A lot of interesting curves and arguments that support what I am hearing. You have steeled my resolve. I sold mine yesterday and will start a Visaton 200-B project in stead!

I've wondered why every time I've heard them as well.
Maybe just repeating the hype from the advertisement site/forum;
or haven't heard much else to compare to?
Or maybe different peoples tastes really are that different...

I really don't find any of the Hawthorne/re-labeled products anywhere near e.g. Altec 604, much less good Tannoy quality-- (which yes, I find colored, but really like).

Sorry about reviving an old thread.

Bit the bullet some years ago and got the Sterling silver iris 10".
They are very dusty from 2 years of storage. Really liked the Radian driver, ran it with some beta 15's from about 120hz down to 50 or so where my old 320 l (now scrapped) TH took over.

Have been contemplating stuffing it in a 60l sealed box for a while now, and possibly do some new xo for it, but then again I might just let it collect more dust until they can be used for something interesting.

you could possibly use them in a closed box with an active crossover and linkwitz tranform to change the woofers Q.
Linkwitz Transform | MiniDSP

as they come from hawthorne they are pretty much useless in my opinion. no waveguide, (high xover and bad dispersion) fullrange on the woofer with obvious breakup and distortion, and so on.
i honestly cant belive how these people still stay in business after a decade with no logical improvements to their designs at all.
the 15" PSI i had still gives me the shivers..

Usually when someone describes a speaker as giving you the "shivers" its a really good thing. Despite what multitask might try to say, I own the PSIs and really like them. In the right OB they're great. I suspect multitask didn't bother to optimize the baffle before giving up on them. I don't think they'll work in an enclosure unless its huge -- the Qts is too high.
