I am going to build a sub for my home theater system, and I ordered a tempest driver with a 250W @ 4 ohms plate amp from Adire. My goal is to make a sub that sounds awesome with music and movies alike. What I am a little unclear about is what dimensions to use for the box. I used the WinISD program, and played around with different values for port tuning and box size.
The graphs looked nice and smooth with a 260 L / 9 cu. ft. box. The port is 3" diameter and 6.8" long, tuning the box to 15 Hz. Is this a good way to go? If I make a 2.1 ft cube with 3/4" MDF, will that be sufficient? The graph didn't shift too much with slightly different values, so I gather that lack of extreme precision will not ruin my project results. Also, will I need to reinforce the MDF somehow? Or will gluing and caulking it be enough to keep it together?
One last thing...I was originally going to get a router, but then I figured that getting a rotozip would be better for this project. There is a circle jig accessory for the rotozip, is there any particular reason I should get a router instead?
