Hi everyone,
I have a pair of Electro Voice Pro 12-B's that I want to build an enclosure for. These are going to be used as garage and outdoor back yard speakers for music. I do not have any experience with box design. I have purchased a few flat packs from DIYSG but this will be my first build from scratch.

My question is, if I am using these outdoors does it matter if I go ported or sealed? The specs call for 2.5 cu ft and that seems small for a 12" speaker. I have never played with WinISD but I am going to play around with it. I have provided a link with all the speaker specs, and I sniped a portion for the box size. If I port this speaker will I notice the low end that much outdoors. I'm also in a neighborhood and I can play it loud occasionally but for the most part it will be at medium to low volumes.

They're not designed for anywhere they'll get damp so useless under eaves etc.

In a 2.5cuft box it's not going to have much bass at all. Hence, the note about going to 6cuft tuned to 40hz.
Thanks for the reply, I am just now starting to play with WinISD. I am new to it so it is a learning curve for me. I just downloaded it this morning and had to input the specs for the speaker as it wasn't in the database. I barely got going before the wife told me I had to help her with other stuff. When I glanced at the graph from the parameters that I put in it looked like it was only showing the low frequencies. Is WinISD only made for Subs, or can you use it for 2 way speakers?

Yes, They will be in the garage most of the time. I have some small outdoor speakers on our pergola for normal days, but I want to pull these out when we want to party! I was going to finish the box with an outdoor UV urathane. I also thought about getting a fine mesh grill to keep as much UV light off of the speakers themselves. I thought about covering the speaker grills in a fabric as well. I'm not sure how that will look, or if I can get the fabric to not look all bunched up.
