View Full Version : square port questons...

I have 1 5x5 square port tuned to about 35 Hz, however I realized that I need 4xmore port area for it to be "correct". (roughly 100 sq in. neeeded) So can I just make 3 more of these same ports and have it be ok, still tunred to 35 Hz, or does that effect the Hz?
