SPL box for dmx 15

[loud by design]

 Guys what is a good box size to start with for a DMX 15. I will be using one D5000.1 for power and I have up to 5.5cuft to work with. The car ( my Acura cl ) peaks at 44 hz.And port numbers will help but not a big deal.Thank for any help.

That's plenty of room for 1-DMX15. I will work out the dimensions and port size. What dimensions do you have to work with, max for Length, Height, Width?

I got 32 w 20L 18h. Can you also work some numbers for the DMX 12 to.

build it as big as you can. Tune it to 40Hzwith 50sq.in vent area.

X-max1 thanks for the information on the 15 but I may go with 12 so a can get in meca S2. What numbers do you have on the 12?

[xmax-1]

for the 12" DMX, try 2.5-3 cubes with 40sq.in of vent.

O.K. X-MAX looks like one DMX 12 with one or two D5000.1's . I need to do about 145 are so in  S2 I will be hitting you up for some help from time to time  if that's o.k.

This is for burps (tones) or music?

For tones, 3.5cubes with 50in^2 vent area tuned around 45Hz

for music....3 cubes with 40in^2 vent area tuned at 35Hz

Apply 1500-2K for 30 seconds and have a great time!

O.K. just build a 4.73 to see how well it would fit. That is before bracing, sub,and port.

Don't feel bad. I've worked everyday this week (no day off) and last week I was out sick (kidney stones) for 3 days. NOw Ive got to get to work on the van again. So much work.....so little time.

Just got the sub today, I went with the DMX 15. I made a test box that is 3.5cuft with 2 4" aeroports 12" long.So far it is not working.The next box will be 4.73cuft but I need help with the port.( That's you X-max ) lol

Not working? Sounds like not enough port area. (2) 4" ports is only life 24in^2. Need to double that for SPL. Will have to play with the length to get it right (to find the hgest score).

Keep one thing in mind.........SPL vehicles usually sound bad due to high tuning. This means you need 2 enclosures and 2 subs.lol........GOTTA LOVE IT!


Enclosure looks good BTW.

I missed on the ports and the x-over on the amp. The port calcuator said the box is tuned to 20hz, so I need to cut the ports down 5" each to get it tuned at 44hz.What's the break-in for the sub and can it take two D5000.1s.Also my series/parallel wiring came to 1.4ohm before I put the sub in the box.
