Sealed enclosure questions..

[Defo]

Hey,

I'm about to build a sealed box for my two Klipsch RF-82 woofers, and I wondered..

Should each woofer be in a separated chamber by themselves, or both in the same chamber? Whats more common?

If they see the same signal then the same chamber is fine - better in fact.

Better how? I've seen analysis that showed no significant benefit to separating chambers, but what's the upside?

If the small signal parameters are identical you can safely use the same volume (especially if you mount the woofers symetrical) If not it's better to use separate volumes.

I assume you are going to connect the woofers in parallel? This means that they will not affect eachother electrically if you use a voltage source (read typicall solid state amp).

By using separate volumes you don't need to worry about any mechanical/acoustic imbalances either.

Things is that if the woofers is not identical regarding small signal parameters they will load eachother mechanically.

The effect (if any) would likely be small though.

I was simply thinking of less wood taking up space, nothing profound.

Yep, they are both fed by the same signal. Will use the same chamber then. Thanks!

Awww, mannnn!! I was hoping you'd say something about reflected sound through the cone
