I have 3 questions about designing then building a sub box for 2 x 12 inch subs.
1. Assuming the interior cubic feet would be correct/ideal for each sub, does the actual shape of the box change the performance? eg. square box, rectangle box, trapazoid, or circle shaped box.
2. When building this box, is there any difference or advantage in keeping each sub separated with a dividing sealed wall? Are there any pros/cons to not having a separating wall inside the interior of the box with 2 subs?
and lastly... 3. If a person is designing a correctly sized ported box with ideal sub specs, (incuding tube length and tube diameter) does it matter on which side or sub box wall the port tube is placed?
1. shape isnt a big deal w/ sealed boxes...but it can cause some problems w/ ported boxes.
2. if both subs are getting the same signal, its just fine to them in a common chamber. but if the subs are getting slightly different signals, they will "fight" each other.
3. sub and port placment can play a roll in how loud and how clean a box sounds. (ex, hatchback cars tend to like subs firing up w/ ports firing back....full size trucks tend to like sub and port firing up w/ the port on the drivers side and sub on the passengers.)
Most boxes have the sub and port firing the same direction.
