IDMax 12 v.3 D2 Enclosure

[cas0586]

Picked up an IDMax 12 v.3 D2. Looking to build an enclosure for it. I emailed IDMax because I can't find the specs for v3 D2 so going by D4. Need 2.55 cu ft and tuned to 28Hz. I have 15"H x 12.5"D x 34"W for the enclosure. With 0.75" MDF this is 2.7927 gross cu ft less 0.12 for driver displacement. So, 2.6727. I think that is close to enough to end up with 2.55 after port volume. Can anyone help me design the port? The port/s have to be out of the front. So I am dealing with less than the 12.5"... is this doable?

In that space you gave, using a slot... single baffled, braced, 45'd and for up to full rated power, the best I could come up with would end up as 1.98ft3 @29hz, 13.21in2^ft3 or really close to that.. if you want more volume, I'd suggest an aero or round port. The port I ended up with was 13.5" tall x 1 15/16" wide (26.16in2) around 38" long and that's minimum for up to full rated power (1000 watts). What amp do you plan to use?

The space you gave is probably gonna end up at 2ft3 net with a slot... 2.15-2.25ft3 with a round. Bracing and 45's I use will eat a bit of volume... .09ft3 to be exact, but If I leave em out the port area will be insufficient... the added volume will put velocities above where I like... it's that close. And if you use an aero or round for that tune (28-29hz) i'll be kinda long too , and possibly kinda difficult to do in the configuration you want. The depth should be ok... barely, at around 9 1/16" to play with and the driver looks like it needs 8.15" depth.

I have an XTR1500.1 I'll be using.

I guess I got the dimension wrong. If it helps I can add some depth and width at the expense of height. I can 36"W x 14"H x 16"D if that helps anything. I can put it in through the cabin that way and get it to fit. That is a bit big at 3.61ft3. To make it closer I'd rather give up depth. I can't really have a port sticking ut of the enclosure. Appreciate your time.

Can you afford more depth? You can cut everywhere else but need more depth for an aero port to work unless you're comfortable with the port being 1.25" from the back of the box.

I got 13x30x16 (hwd) and one 4" aeroport 14" long...2.51cf tuned to 22.88hz.

Lol... what's the vehicle anyways?

Lol... what's the vehicle anyways? 

I see why you're laughing. It's actually 28.22hz lol.

I can do 35x15x15. I believe that is it.

I think at that size with a 2.25"x13.25"x28.5" port is ~28Hz and 2.25"x13.25"x24" is about 30Hz...

net volume would be 2.7ft(28Hz) or 2.77(30Hz).

Math was never my forte though. So... ?

I use Torres box calculator (download free online) and when I build my boxes, I'm not concerned about 45's and only use one 1" dowel to brace the front and back together. I've done slot ported boxes but would rather go the aero port route...less headache with limited tools.
