How will the speaker shaped by kenjit sound?
If I had a speaker company my speakers would have to be perfect. No ringing or resonances. Just pure music.


Me, the dog, the rabbit, and the GOAT, all of our heads, cocked sideways. The chickens didn't though. BOING!

NO RESONANCES, either... hum! At least some ok..
Something gotta come out of the front of the speakers, just saying K!

;-)

Kenjit is wrong concrete. Does not resonate the issiue is weight and ability to ship without damage


Jim thiel and paul hales had speakers with cconcreate front baffles

Both made great speakers


Just got in cast  ironand graphite speakers from jern they sound unbelievable

0 cabinet resonanance
they sound like 10k speakrs yet cost about 4k

Compleately disssapear speed and articulación are. Off the charts
when used with a good sub willl embarass a lot of extremely expensive speakers

I had some Essence speakers in the 80's.  Each driver, 5 per side, were mounted to concrete, then finished on the outside with medite, then walnut, except the bottom, woofer.  Each speaker housing was separate for time alignment and made a nice pyramid.  10k in '82 was a lot of money, but they sounded fantastic. Before and after speakers were Snell Type A and Quad ESLs.

My oh my, I don’t think he is, but I do think you are... CONCRETE is REAL bad.... GROUT mixes on the other hand.. quit good.. Concrete is WAY to heavy because of the rock type and size. Grout on the other hand, less than half the weight (depending on the fluff) and can have a very DEAD signature..

Again NO ONE uses, granite. You cannot use granite. They use synthetic granite, ATH @ Corian... Granite, basite, any igneous rock will ring... It has a very low concentration of silica. The baffle mix has to have a high porosity (bubbles in the mix, but no voids) Igneous rock, is a NO NO..

Some naturally occurring sedimentary, looks good and can work, but has no strength..

Metamorphic, changes under great heat, pressure and TIME. It’s out...
just like Igneous, way to dence, very difficult to work with, without some pretty fancy tools.. The weight, out of sight!! the heaviest of all, ay?

Try cutting 3-20 driver holes, praying the whole time, hole # 10 won’t have a problem, much less # 20..
Now lets add an OOPS or two in the mix... :-)

I would think concrete could work....there are so many thickness you could work with. Thicker for the woofer. There is light weight concrete and you could texture the inside with ie. polystyrene or some media to make it more textured. ...the problem is how the hell are you going to test them....to much work in my view.
