1 chanber or 2, when using 2 subs?

[black_mamba]

I have a couple of TB 8" subs and have decided to go with a ported box for the type of sound and output I want. My question is what will be better, 2 seperate chambers or just one for both? If I go with just one chamber, should I still use 2 ports or just 1 that is equal to the 2 I would have used?

I actually have 4 of these subs, but am only going to use 2 for now. Does the theory for the above question also apply when more than 2 subs are considered (ie should I put all 4 subs in 1 chamber)?

TIA!

when i use larger subs i ussually like to give them their own separate chambers for strength reasons, but for 8's a single chamber will be just fine. I would also use a single port. Just when you design your box, dont forget to take the displacement of TWO subs, not just one

for ported I would go with one chamber. theres more of a chance of cancellation with 2 ports and airspace. There are a lot of variables when chambering a ported box (such as port area, length, and volume. if you can be totally precise you can do 2 chambers, It would be fine.

i dont think he understands,mono means you are using a single output on the amplifier,stereo means your are using 2 outputs on the amp,right and left.

Wow! I'm so glad I found this forum. I walked away for only a little while and already so many responses! Anyway, back to topic.

I am running them mono with one amp (otherwise I wouldn't have even consdered 1 chamber).

So I am going to build a single chamber for both subs with an single port. Is there any preference as to which direction I should have the port face? can it be on the same side as the woofers, or will that cancel out the pressure?

Thank you everyone!
