These speakers are developing a large cult following. A 10" full ranger with a super tweeter. Anyone seen, heard or tried to develop their own DIY pair?
The main driver looks like a Fertin but i can't verify this i can't find any info about Fertin online. As for the super tweeter i have no idea.
I would love to have a go at making a pair myself and would appreciate any help that this forum might be able to provide an how to get started.

Cheers

Emminence they are.

How about a much cheaper kit that's very similar?

I have never heard them, but they look so good.

I think they use a low q driver in a small straight t-line mass loaded via base and the floor.

beaming would be a bit of a problem with the 10" driver

They're not accurate: look at the specs on their site. 35Hz @ 101dB from a 10" in a modest TL.... stinks to high heaven. MAYBE corner loaded.... IF they're lucky. In a 'normal' setup, it takes a refridgerator sized speaker to achieve that.

Now, they may sound great (all indications are that they do, and I'm fond of fullrange+assisted and/or wideband high efficiency mids), but they're fulla hooey.

I just love phonies

In my simulations with MJK`s ML-TQWT sheet the unmodified Eminence and other medium-Q drivers don`t work. I get better results with low Q like Ciare PH250 (requires supertweeter) or Audio Nirvana Super 10 (no supertweeter required).

i read the audio asylum thread nothing definitve but people appeared generally under whelmed by their efforts.
Badman or el'Ol might you sugegsta simialr project (full range woofer with super tweeter assistance) that has had better results.
I built a pair of Jordan Tl's a while back and they are still my reference but i want to try something else...

My own efforts are kind of esoteric: I have a pair of Rethm "The Second" Cabinets, using Fostex FF225k instead of lowthers, and heil AMT 1s as supertweeters. Active XO at 6500Hz, first order (still experimenting) A little more info here.

My Blog

The Hammer Dynamics seems to have quite the following, and certainly at $650 is very very reasonable.

I am currently very happy with the Ciare HX201 in a reflector-less radial setup (25x50x100cm TQWT) I could recommend if your listening room is not too high, but I think a druid clone is not impossible.
Apart from the two drivers I mentioned I could also recommend the 12" Fertin, simu looks fine. The 12" alnico supravox seems to have too high Vas.
