6moons audio reviews: Yamamoto SoundCraft YS-500

Is this doable? The drivers are common variety but the horn is exotic. Anyone?

Regards.

When you say 'do-able', in what way? As in a diy version? Sure, if you feel so inclined. The review states what the drivers are, & you can make a fairly accurate stab at the dimensions from the pictures etc. One of Fostex's wood horns Driver / Horn : Wood Radial Horn - Speaker Components should make a reasonable substitute for the original if you didn't feel inclined to design & make / mould one yourself.

As for how good it is, can't really comment, other than that I suspect the LF might not be especially linear -just a guess, I haven't time to stick something resembling it through MathCAD at present.

I like the idea of this speaker and think it's very DIY. Honestly it really is a pro sound speaker that you'd find in a DJ setup but it's crossed over for sound quality rather than power handling with the 6db slope on the tweeter.

Woofer response seems pretty controlled on top but seems to really want a ported or even a sealed box rather than OB... near corners it may plump up the bass but positioning will require fiddling. I'd partner this woofer with the econowave tweeter we've read so much and forget the (very beautiful) wooden horn.

Yes , godzilla , it's true. But ... this speaker IS the wooden horn , together with the beautiful veneering , the bar beside the woofer...it is also the binding posts on the upper side of the box ,the spikes on the bottom...
And as Scottmoose said , the non linear response in LF could be corrected with a Linkwitz Trasform , even if that wouldn't be much "purist", which I think is the idea of the project itself.

Wonder why they do not have used the ALPHA15A with a QTS=1,26 ?? the Delta QTS is low.

How about beaming for 15inch cross at 1.2kHz?

It's not perfect, nothing is. Once positioned properly the sweet spot should be a nice place to be. Having used a 15" Alpha i can't imagine the Delta or any other 15" driver would be any good at midrange but who knows? The designer brings that tweeter in as low as it can go using the 6db slope. Probably for the price a larger 2" compression horn might do a better job crossed under 1000khz. Seems like an interesting speaker but it will have a character like many other 'hi end' products.
