two differently tuned ports?

[gadgeteer123 21]

I was wondering if you could have to ports on a enclosure and have each of them tuned differently, for example, one would be tuned to 30hz and the other to 35hz, would this enhance the sound or ruin it? I'm just curious.

Ruin it! Cancellation!

Read up on 6th and 7th order bandpass enclosures!

Not a good idea. just my oppinion.

What would be your goal behind an enclosure like this?

I was just thinking it could maybe give a wider tuning range.

I was just thinking it could maybe give a wider tuning range.

Good thinking, but Id bet it would sound like shit.

[gadgeteer123 21]

ya, thats why I asked.

[Argent Audio 54]

Yea there would be major cancelation. You might want to look into a PR design if you want to open up your tuning range.

Hmmm I've wondered about this to. Now I know. Good post!

You're basically talking about a 6th order bandpass. Only one person caught that.

The Subwoofer DIY Page - 6th Order Bandpass Systems

It wouldn't sound like shit if built/designed properly.

If you're looking for a wider range of frequencies though, and no one will design/build a 6th order for you... build a sealed box. You'll lose output, but all the frequencies without the boost around tuning will be there.

Could also think about an ABC(aperiodic bi chamber).

Wow that's a basic solution, it'd be a bandpass enclosure why didn't you listen to Old_Skool?

That was an interesting read, I don't think I'd ever do it, maybe in a home situation if it would work in a HT setup. I was just thinkin.
