[QUOTE="SPLAudioHz, post: 7042626, member: 625822"] At 35Hz you can run a 4" Dia. port at 15.5" long and be just fine. I can calculate the flare on the port as well if you like. If your interestedL: a 5" @ 35Hz will need to be 25" long a 3" @ 35Hz will only need to be 8" long a 2" @ 35Hz will only need to be 3.14" long If you wanna play with some numbers, here is how I put it into my TI-84 (just fill in the blanks with your info): ((14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2)))) I used 1.5 cu ft as the desired enclosure space and 35Hz as the tuning Fq [/QUOTE]
