Custom enclosure dimension help.

post #1 of 11
Thread Starter 
Building my own subwoofer enclosure for my home theater system. I found my poison of subwoofers and navigated to the recommended dimensions of the enclosure. The enclosure will be ported by the way. Regardless, since the dimensions are only in reference to one subwoofer, do I double the dimensions to house both subs in one enclosure,therefor doubling the space? Or do I build the box meant for one subwoofer and mount a second one I. It?

If you know the exact dynamic parameters of your sub, use this little piece of software. Works very well, and simulates the frequency response of your final product for your reference smile.gif

The built in speakers are only from Visaton, but you can modify the parameters of the speaker to your liking.

the sub woofer should have come with specifications for the size of the enclosure for both ported and sealed configurations. use those specs. if you lost the reference paper im sure you can find it online at the mfr website.

Don't know the answer to that question, but building two boxed and attaching then together would work.
I would suspect that two drivers in one box would require a substantial modification of both size and proportions compared to a box with one driver. And why ported?

if you have 2 woofers in one enclosure the right way to do it if it is a sealed not a ported box is to have both chambers isolated internally and each chamber at the specified dimensions.

ported gives you lower freq.

sealed gives you a tighter bass (wich has its benefits) ported gives you deeper base, can also give you a nice tight bass aswell but will req a larger amplifier and a nice low impedance woofer

Phase also has alot to do with what you hear. That includes all speakers.


phase can be changed at any time.. not an important factor at this stage
