i just purchased construction ply from bunnings to do my next two SS15 cabs. its a bit crappy tho, has knots and voids all through it but i didnt want to pay for the premium stuff so ultimately its my own problem. i do however have an issue with the sizing.

my first cut for the side panels, had to be adjusted, which i didnt do before cutting

aus sheets are 1200x2400, not 8foot by 4foot. (1220x2440) so, ive already adjusted my cuts to suit, but where/what would you guys adjust in the plans to suit the smaller sheets? (so i can be sure i made the right educated guesses)

no, didnt see anything even resembling that at my local store. its too late now anyway, its sitting cut up waiting for me to be bothered to make some angles and holes.

I found that the form ply at my bunnings was sitting outside, which was nowher near the rest of the wood. can you tell me what to look for when looking for voids or can you only tell once cutting?

when i went to get mine there was only two sheets left. So basically i got what was there. Lol. Both sheets had knots all through one layer on one side. I found more as i cut in. Thankfully i use PU glue which swells as it dries so should fill any gaps. was exactly the same with the boxes i build previously so its not a new scenario....

well, tbh, ive only ever heard MDF previously, which i must say, i definately prefer the sound of a horn made of ply.

as far as im concerned, i think they sound great. but ive not heard anything else horn wise.

Hi Guys, Before I go ahead and build four of these, Is the cad drawing link from the first page the latest and greatest plan or is there a newer one that's better?

Cheers,
Jaye

Likely depends on what drivers you plan on building with?

As you can see, my path divider coming from the top of the horn is perpendicular to the top, and not angled like yours. However observing the cross sections, this seems to yield a good expansion on paper. It would be great if you could write your measurements more legibly for me

Still waiting for my Delivery of Eminences....

Oh and one more thing: what's this threads opinion on a good finish. Speaker felt, or some kind of robust paint? I already have edge rails and corner protectors on the way.
Did you test these at all? I love the idea of a lower frequency ss15?

We will have an extra sheet to use up!
