View Full Version : HDC3 12" Box Help

07-14-2008, 07:15 PM
OK, i **** horribly at designing boxes so i need some help from the pros. I tried sub woofer tools but they have been down for a long time. Tried re but it doesn't print well. Anyway, can anyone please design me a box (3d if possible) for 1 12 hdc3 tuned to 40 and whatever size port that will get loud. oh, would like the volume to be 2-2.2 after displacement if possibly thank you to all those that help. Going to try and build it this weekend. Dimensions are 41 width 16 height and 14 deep

Thats actually 36hz

Im sure someone on here can tell you how shorter to make the port to get it to 40hz, but i think 36hz will be fine

oh ok i know you had some so if you say it'll work i'll trust you i just thought 40 was supposed to be the best or whatever

I get 34.5hz.

Factor in the extended acoustical length because you are using a slot port and it's tuned to 34.5hz.

Internal length is seen to be 29.0" rather than 27.75" because it's a slot port.
