Here's a link to the Sonosub software that does all the figuring for you. It's a free download.
You enter what tuning frequency and box size that you want. Switch to the cone excursion graph and enter how much power you will be using in the Signal tab. Adjust the power input until the sub is within its Xmax.with winisd, will the software calculate the port size & length for the box after i input the driver specs,desired volume and desired tuning?
That should say 19 hz. The recommended box size is 9.35 cu.ft. A 22 inch sonotube is the largerst diameter tube that will make this work. The net volume needs to be increased abit from 9.35 to 9.75 to have enough clearance between the end of the port and the back of the sub.in the app notes for the mal-x a ported sonotub is recommended at 22x50 inches w/ 8"by32" port tuned to 17hz.
I believe the sonosub program will warn if the distance is too short; it will flag you by having the display warnings text become red (like the example above), if you click on the red text it will give more info, just be sure your driver input parameters are correct.now i will try to calculate a 24in sonotub. what is the minimum distance between rear of driver and vent port bottom?
Yes, you have lots of room between the back of the sub and the port. This sub would be a monster, 118 db down to 14 hz, plus room gain. :yes: :hsd:does this setup look do-able???
