Eskii Posted July 17, 2008 Report Share Posted July 17, 2008 I'm designing a ported enclosure for 3 BL 10's. I Have a net volume of 1.85 cu.ft and tuning to 32Hz. What port area should i have for this and what would the length be.

The Performer Posted July 17, 2008 Report Share Posted July 17, 2008 If I did the calculator right port area should be 80.99 inches minimum, if the port is a square then it would be 9 in square, and 107.8 in. I think this is all right, give it a shot yourself, if you don't want the port to be a square ask more specifically the dimensions you want. Port calculator Quote CERTIFIED BITCHES!!!

The Performer Posted July 17, 2008 Report Share Posted July 17, 2008 By the way, I forgot to link where I got the specs for that sub. Fi sub specs Seriously though, reply back as to what you would prefer as port dimensions, just make sure they sum up to a area of 80.99 inches square. Quote CERTIFIED BITCHES!!!

Unless he means 1.85 cu.ft per sub thats WAY too big. Good rule of thumb is between 10 and 15 sq.in per cu.foot. Then make it about 18" long and go for gold Quote 10.x volts fo' life!

Colin - STAPUFT Posted July 17, 2008 Report Share Posted July 17, 2008 Is that 1.85 cubes per sub or total for all 3?

The Performer Posted July 17, 2008 Report Share Posted July 17, 2008 Is that 1.85 cubes per sub or total for all 3? I'm just now actually registering what I just did and 1.85 total cant be right... That is a tiny box for 3 of them damn things... Disregard all that calculating I tried to do earlier and lets wait till this guy replies back to be more specific, I don't think all those calculations I did are right. Quote CERTIFIED BITCHES!!!

Colin - STAPUFT Posted July 17, 2008 Report Share Posted July 17, 2008 Yeah, if that is total cubes for all 3 then he might have to go with a dirty word *GASP* ....sealed.

Eskii Posted July 17, 2008 Author Report Share Posted July 17, 2008 It was 1.85 cu.ft for all 3 subs. I'm settin the challenge of getting max sound out on min space. I know on Sound Sol forum they say 15 inch^2 of port area, but i dunno if that'd be 45 for 3 subs...

Colin - STAPUFT Posted July 17, 2008 Report Share Posted July 17, 2008 You tune a port for the box, not for the subs. It wouldn't matter if you have 3 subs in that box or 1, the tune would be the same if the internal volume and port size & length were the same..... So- I think you would be better off with all 3 sealed or just 1 ported. Just because you can stuff the speakers in there doesn't mean it will be louder or sound better.
