| Re: Dual tuning of ports
Sorry dude, it won't work.
The tuning frequency of a ported box is determined by the "springiness" of the air in the box and the load presented by the air in the ports.
To use an electrical analogy: Since the two ports are basically in parallel, the load presented can be visualised in the same fashion as two resistors in parallel
With ports of different sizes, each will flow different amounts of air, but the system sees a single load.
Multiport systems like SVS only run a single tune at a time, depending on how many ports are plugged.
