i found something online about a double ported box using 6 inch port tubes.  i experimented with my own design, and my customer did very well at sound competition with some low end equipment.  i just wanted to share the design with you guys and spread the knowledge so feel free to ask Q'sposted_image

2-12'S? Are they sharing any internal airspace? Or do they both have their own vent?

What do you mean by "double ported design"? Do you mean a 6th order bandpass design or simply an enclosure with two slot ports?

Do you have a sketch of what the design looks like internally?

Oic, I have heard of those before.

I just misunderstood what he meant when he said double ported.   

Kind of like this...
