[QUOTE="phantom240, post: 7550426, member: 562504"] Long story short, I'm drawing up a fiberglass enclosure for my 1994 Honda Prelude. It will replace the OE center subwoofer between the rear seats and the *** blocker underneath. Total volume will be approximately 1 cube. The subs will (likely) be two JL 6w3v3 subs, due to having limited width and depth to work with. Plugging in all known parameters into winISD, I'm getting 167 ft/sec port velocity with a 3" Precision Port tuned to 38hz, and I'm worried about noise. I can't physically go with a 4". Is port noise going to be a problem at that velocity? [/QUOTE]
