Solid Granite 2380's L@@K

[Speakertown]

In an (expensive) attempt to cure the dreaded "horn wall vibration,"
I had these CNC milled out of solid granite (My CD player
really hates granite, but I used my turntable on one).
Unfortunatly, I crushed an A-7, oh well. It takes 4 strong
guys (or forklift) to move them. Custom tweeter horn uses
2404H magnet/phase plug. Hey Widget, how about
mass-producing these?. Actually, could you make some
out of solid walnut?, he he

Is the granite the good swedish one or the cheaper varieties of this continent?

Actually I have thought of casting horns out of a stiff rubber, say a Shore 80-90A. I doubt you could get it to ring and it won't take a crane to move.

Hey Widget!

You should start with 2344 copys. As we learned from Ralfs desaster there is a market for them now.

[Mr. Widget]

But I don't want a 2344.

Besides, I don't know if large butt cheeks made out of rubber is a good idea. I think there are other people already making those, just not for audio use.

:shock:

Good grief! I thought I went to extreme measures sometimes!

What a piece of work! That's about the most impressive horn construction I've seen, EVER...

Alex.....I don't know the origin, but it's an industrial grade
that is uniform density and much more stable than the
cosmetic grade used in counter tops and floors. They use
industrial grade for things like precision flat-surface stones
that are use to measure off of for precision part making. You
can find these in certain factories (like Boeing) or larger machine shops. That's just one example.
