Hi Guys
Have been looking at building 8 tapped horns, drivers i have are B&C PZB40's
Have simulated these in horn resp and must admit im impressed with the results if loaded in the Tham15
But just wondering how these drivers would fair in the SS15 ? found a few details , but for the life of me i cant work out how to plot it horn resp
Be greatfull if someone could do this for me
specs are ...

The SS15 is a seriously nice and well balanced design, all be it in the good company of the other nice ones floating around here, I look forward to a comparison between the two that has caught you eye, no matter the outcome, yes seriously 
PS. Jbell - you're toast (and I do emphasize the "" )
Good luck with the builds, and thanks for sharing.

And you can bring the 'jam' for my toast.
Game on friend !!!
This is seriously one of the more respectful and knowledgeable sites around, and part of the reason I frequent here.
I too look forward to the builds.

This is easily the best thread so far in my brief time here on this forum, you guy's almost got taken in at work today, I laughed out loud when a saw this and my colleagues must have thought I had finally snapped, absolutly brilliant, thanks !
How shall I top this ? is it at all possible ?
PS. Jbell - consider it brought
Thanks for all the replys guys, just ordered the guides and bits for my router today, just need to work out how to add handles to the Tham without seriously affecting the horn path
JSK.. would that be mr grime from SP? could be worthwhile as were both local .. could also try a variety of drivers
A thanks to Anders and Jbell for their designs .. wish i knew where to start
Lets just hope the toast dont include my voicecoils haha
Any recomendations on measurement equip / software?

My only concerns with the SS15 is the material thickness.. as a "master" carpenter of nearly 18 years and an ex basshead SPL junkie with a respectable 151.7db some 15 years ago .. i think 1/2 ply is just tooo damn thin for this type of enclosure and could possibly lose some fidelity to panel flexing .. so should be pretty interesting
@johnnypyro,
yep grime from sp. I did not bother with handles on all of my boxes, although I have done the cone compensation mod suggested in the post above, this would allow handles to be cut in the void behind. Also have a couple of boxes with speaker clamps, so would be easy to try different drivers.
