I wish Tom would critique some of these boxes, but that's asking the guy to cut his own throat.

I work with "Relay for Life" and plan to build up a PA to loan out. The Crown XTi 2000 looks like a good way to go. If you have any hints, please e-mail me.

I walk relay each year, and always cringe at the 15+comp cabinets with no subs that always show up... However walking all the 80's music they always play is fun with friends.

The 'key' to a good sounding TH in my opinion is to minimize parallel walls/standing resonances, and to minimize similar path lengths. It's kinda like playing a chord on a piano. The richer the chord, the fuller the overall sound.

Just as soon as I can get healed, I will get the build going again. I can't tell you how excited I am to get them completed. Will be glad to replace the W-bins we use now. Sorry for rambling on.

Don't give up on me and the build, it will happen and I will post pics and reports on performance.

Thanks Mike
Ouch, really sorry to hear that mate, Hope you get well soon.

TIA,

If your hornresp was on the 2x2x4 box shown in that link -- I don't like it, and won't build another. It's personally not worth it to me to refine it. It was a 150lb experiment, that while salvaged for the intended install with a couple reflectors... it did not achieve what I was looking for -- A cheap, easy, quick build that would satisfy a large number of the installs I have to do.

The single sheet design does that for me. It's the cabinet I'll build in the future.

Right, you linked it, so thought it was the one folks were referring to since I haven't been following this thread regularly.

Default could you use this, or are the specs unsuitable? LAB 15 at 70% discount

Eminence Lab 15 High-Power 15" Subwoofer and more PA Cabinet Parts at GuitarCenter.com.

saw this on the other forum and I thought of you!

WOW that is a great price! About $100 below wholesale pricing. Wonder what is going on that they dropped the price that much? The big E must have lost a big order buyer or something.

How would the LAB 15 do in a SS-15?

There is a "MKII" of my THAM15 (aka andershorn) in the works, the modifications is based around four 45deg. refelctors positioned in the horn path, one of wich also acts as a chamfer at the mouth increasing S4 by a factor of approx 1.2 and slightly increasing L34.

These changes are along the lines of what William and I once talked about some time ago but i did not act on it, but now a friend of mine here in Sweden has offered to try this mods out and compare them to the original design in an atempt to improve the design.

Hopefully these changes will result in a slightly higher over all effeciency and supression of the 180Hz dip, but this remains to be seen.
