I personally use flattened expanded mesh. Here's a pic of some cb-18 using the same mesh for grill for inspiration. (it really stiffens up the front panels, and keeps things from vibrating)

Nice grill

jbell, Thanks for the info

Does that explain you absence?

nope... just been busy. that pic was a gratuitous copy from a speakerplans post -- not mine.

Since that builder used the same grill material as I do, I thought it might be helpful to cross post the picture.

(btw -- right now my shop is littered with test cabinet designs -- when I have something of value to post -- be sure, I will....)

Cool project, look forward to seeing a build of this! Didn't know you could horn load a cone as big as 21", or is it fine becuase it's a tapped horn?

the plan has changed a bit.

you can load any speaker to a horn.
its just that some wil work better then others.

you can make panels 10 and 11 12 mm wood,no need to make them 18 mm heavy.

hi stanley
wel i was looking over the design,when saw this.
it maybe saves 1 or 2 kg doesnt make much difference tho.

 

[olsound]

Erik how much sheet of plywood will be needed to make one cabinet.

 

[epa]

2,5 sheet of 4'*8' per cab.

the vertical pannel bracing of 10.32 mm (perpendicular to the speaker)need to be cut a piece out where the surround is,of 15 mm ,so the speaker wont hit it when getting close to x- limit.
atm you have "only" 18 mm off max excursion before the suround hits it
