Bronze Member Username: SchinnerPost Number: 88 Registered: May-07 | hey already got it drawn up and in winISD and sketchup. seems like good numbers but with a short port 12.5" x 2" x 11.75" will it sound good?? (including end correction factor) its 3.99 cubes after port and sub displacement tuned at 32.5 hz...it will house 2 12" xplodes my main concern is when i see other build logs the ports always end up being fairly long and bending around in the box, being that they are wider requiring a longer port....according to winISD the velocity out of the port shouldn't pass 14.5 m/s...

Bronze Member Username: SchinnerPost Number: 89 Registered: May-07 | nevermind....port area should be between 12-16 in^2 per cu ft....it was at 25" total...meaning 6.25 in^2 opps...good thing we didn't build it yet anyone know if 3.43 cubes at 32.5 hertz will work good for 2 xplods (12.75 in^2 per cu ft)? |

They are loud, they just aren't he best sounding subs around. That said, for an Xplod 12" pair of subs (shared chamber) I's make the box 3.6-4.4ft^3 and if it's for daily/music use, use two 4" ID ports (one per sub) (flared if you can) tuned to 28-32Hz range. It'll play deep, be tight, and handle good power. I'd personally lean toward the larger box size. |
