jbell's set of four tapped horns

[tb46]

Hi,

The EV T18 specs say: 11.5"W x 24"D x 32.8"H, that's 4 ft^3 gross internal volume minus braces and driver displacement. If you glue two of your T18s together you might get close to the 8 ft^3 you are looking for.

Regards,

Oliver,

Your specs are wrong, the T18 is 24.8"W x 24"D x 32.8"H.

Big enough to make a decent size BR.

Hi!

So, if ply is 18mm thick, recess of front panel around 4cm for grille, gross volume should be around 252,3liters.

Net internal volume = 252.3liters, minus braces, minus driver, minus ducts and we can play with sim program and come out with a good box IMO.
The image at post 467 shows refurbished boxes made so.

The stadium horn I will only run up to 50v, and the ss15 I feel comfortable running up to 63v.

Does someone have an updated Hornresp input screen for the Stadiumhorn to share? The one I have doesn't model as well as the ones I see here.

A few other questions regarding the Stadiumhorn:
-will making it 24" wide (external) impair the horn's output much?
-will making the bottom rear corner of the enclosure angled (for casters) impair the output much? (I don't think it will - just verifying)

You don't have any lumber supply stores that sell Baltic Birch?? my local Dykes didn't have any in stock, but the Dykes not far away did have plenty of it.... $79 per 5x5x3/4 sheet....
