I built my box for my two 12inch's and it just really doesnt sound as powerful as it should
maybe its leaking?
ways to stop it?
any help be great dudes

help help

1. what type of box is it? (ported, sealed etc)
2. what volume does your sub like?
3. what did you make it out of?

chipboard, just put together

there are two black pioneer 400rms there now.

Check the phase of the wires firstly, just quickly try reversing pos/neg of ONE of the subs. (at the amp or at the sub)

then get back to us...

And might be a problem having the coaxials in the same enclosure as a 12".

Is the box split so each sub has is own dedicated space?

Quick diagram will help if possible.

1. How did you seal the in side of the box ?
2. You have small speakers in there are they in the same Chamber as the subs ??
3.Have you made sure there s no air leaks around any of the Woofers ???

there is no divider in the subbox, i think there are air leaks those speakers in the box are just for show and i have removed one now for air flow i think iv got the wire matchings correct

K u need a divider in there, otherwise each sub is going to be working against itself.

Check the box for leaks to, you may want to make a proper one out of MDF and brace/seal it up properly

Peace

I do beleive Chip board does allow air to escape through the fibres.. MDF would be a much safer but hazardous Idea, make sure you wear a mask when cutting it..

I really think that wouldnt be an issue(chipboard) has worked fine for me in the past. Try placing something inside to reduce the internal volume or try stuffing the box with loose packed (dacron,fibreglass) material which you can get about 10-15% more volume in acoustical terms.
