This was kind of a "hurry up" box, so there are some rough edges. Alex talked to me monday night about making him a box, I got a tad done Tuesday because I had to help a friend move, so I pretty much built this box in ~5 hours... which is pretty quick for a non-pro like me

Anyhow, it's 4.28 @ 34 for a pair of RE MXes, which will be powered by a Kicker ZX2500.1.


Alex will be getting it carpeted later, so I did the little groove thingy that PV Audio so helpfully posted about. Thanks, mang!

so those are your old subs we're putting in there? I've always wanted to mess with an MX since they're such interesting subs. Honestly, those MXes might could blow this box to bits since it's only one layer of 3/4" MDF. Becuase of space requirements, he couldnt fit a double baffle or anything. We'll see.

yes those are my old babies...they are some of the nicest subs ever...no double baffle? hmmm, that's not a great idea, hopefully they don't eff up...because i had an issue with one of them where the box did start to crack...we'll see...

Yeah, it could only be 17" tall, and to go any smaller would've put him at ~3.5 after moofa displacement. He wanted as much airspace as possible. All I could do in the time I had as far as bracing is the brace between the holes. Feels solid, though.

Oh, and the caulk is messy because I used that spray **** in a can for the first time... Never ever use that stuff. it's messy as hell and a pain in the *** to use.

Whats with the piece in the middle? Bracing? Should have used wooden dowels, or at least used skeleton bracing...Nice work

I'll spray some caulk in your face, pen15.

Yeah, it's just a piece of MDF for bracing. I wouldve loved to do skeleton bracing, but I was out of wood big enough to do that.

You say it with such conficence. Sounds like you enjoy caulkslapping a bit too much. If I were you, I'd either find a shrink or a gay pride parade :fyi:

that brace really takes away from a smooth flow. I would highly Suggest not doing that and using a double baffle. It will work but theres more to be had

Ill see if i can go a bit higher and add another layer of MDF up there.. Is that doable?

.75" is not a lot of space... I would suggest adding another layer for the baffle, too.

would i have to add it to the port part, or can i just cut it off right before that..

James Bang

if you add it to the port part, then tuning will change a bit. tuning will be a little lower.

i see, ill just add more on the box part then

I would change the blade on your table saw to a cross cut blade. It has more teeth and provides a cleaner glue surface cut. The propper blade for the job that is also SHARP is very important for geting a good crisp edge when dealing with sheet stock such as MDF>

adding a double baffle = win.

If you need help, lemme know.

jordan, if i added a double baffle, could i get rid of that brace in the middle?

jmanpc
06-14-2007, 01:15 PM
yeah. It's just screwed in, so it wouldn't be a pain to remove. lol and i assume it didnt get stolen? those air mattresses will do the trick every time.

that brace = bad idea :fyi:

jmanpc
06-14-2007, 01:19 PM
it's only about 6 or 7 inches wide... the angle makes it look like wider, though. Theres still a good distance between either side of the brace and the wall. shouldn't cause any interruptions in airflow

we also listened to it last night and it sounded good. only on 1100w @ 2 ohm from my ap, though :(

Those MXs will be happy with the ZX2500.1 :D
