Not to thread jack, but yeah, I had a similar question when I built a box a couple of weeks ago.

Here are two designs I came up with:





The funny looking thing is a subwoofer. Does it matter where it goes? Is anything different?

It's not urgent, I ended up building a box like this:

many ppl say sub close to the port but i find it best to put it far away from the port in my car

I too had this question when i built my 2-12" cvx's. Then i thought about it and the woofer is just displacing air in the box so it really shouldnt matter where it is... but i still want advice.

anybody?

Sure it matters. you dont want the sub too close to the port because the air is going to take the path of least resistance which would be out of the port opening.

It kills me when i see someone build a huge box but then put the speaker right next to the port. how does the remaining air to the non port side act as air suspension the same as the easy flowing (out the port) side?

the idea here is to use the air similar to that of a sealed enclosure as air suspension only the way the suspension or air load against the sub works is dictated by the resistance of the port. long story short the sub needs to be on one end of the box (to most effectively do its job) and the port on the other (to also most effectivey do its job as well)

as far away as you can.
