Need Help Designing 4th Order (Box Built)


Recommended Posts

I would just go with the 1:1 ratio, 2cubes seal, 2 cubes ported tuned to 45hz and have a nice broad flat response. But being in a small truck, will still have pretty decent highs.

The dimentions I made the first box to where just a shot in the dark, first attempt. As long as the box fits within my max dimension, the smaller the better but it doesn't matter.

I might make a 1:1 ratio and a 1:2 ratio to compaire. So 2cubes sealed is good?

I may also do switchable ports to see what each tuning will give me.

ive read from many people to do a 1:1 ratio, but every time i have tryed the 2:1 they either peak to low or peak to high. So i would do a 1:1 so it has a nice bandwidth, and tune it from 45-50. From my experience, i have the exact same sub sitting in the corner of my room in a 1.5 cube box tuned to 33 hz and it still peaks high and doesnt really like the lows, gets warm on 200 rms. I would tune it in the high 40's which will still have a lot of lowend, prob more than you have now.

alright i was just wondering..and if you were to stick with those dimensions i would go with wat socky said and tuned in the higher 40's...and i would have it loading off of the passenger side wall as that is where those trucks seems to get loudest

What do you mean by loading it off the passenger side wall?

I going to be finishing it tomorw.
