DC Level 4 M1 Ported Box Design?


Recommended Posts

Posted

I need a box design for my M1 Level 4 with Level 5 softparts. I really want to hit lows, but I'd also like to maintain a good SPL level as well. Low notes would be more important. Does anyone have a design for this?

So your current box, can you describe your aimings or better yet a pic and tell what's the problem with it?

With my current box, its just doesn't hit lows like i think it should be able to. I don't think it's the sub. I think its the box.

What I meat to ask is sub front? port up or side? and is your sub fully broken in?

Giving info about your box for example dimensions and tuning, might help to determine what really is the problem, it may or may not be the box.

So by chance I find the data of your box in another thread 25x36x14.5 1 8" aero 11" long

You are 5.5 cubes @ 38Hz without a double baffle

..... and 5.1 cubes @ 39.5Hz with one.

There is your problem. You are rather low on net volume and high on tuning.
