my friend built this box a while back an i wanna know if it would work well with a alpine type r 1243 im a noob when it comes to boxes
ext dem. 24wx16hx16L port. 14.5hx2wx38L the port is like a s shape an i believe its 38 inches long? could you tell me what the box is tuned to an how many cubes?
If you don't know already, L * W * H / 1728 = cubic feet (in inches).
Obviously you don't calculate using the outer dimensions, and you didn't give the wood thickness, so how could we possibly find out? We need the baffle thickness too, like maybe the baffle is 6" depth, that'd total a lot less NET/grosse space.
Use the 12 Volt Port Calculator, you are so not inept to boxes when they make it this easy to calculate for one. You'll be to within 3 Hz of the tune because you'd need to calculate for an end correction (for instance, a port that's physically 20" long doesn't equate to 20" length given on the calculator). Measure from the center line. I'd explain end-corrections, but I just got off my 1st day at a new job and I'm broken. It's somewhere here anyways. Google "ecoustics forum end correction" and you're guaranteed to find me explaining it in 10 posts.
6" baffle? I have built some of the most ridiculous, over the top boxes maybe ever, and I have never even come close to THAT thick of a baffle. That's six plies of 1" MDF!
Post from above: "Obviously you don't calculate using the outer dimensions, and you didn't give the wood thickness, so how could we possibly find out? We need the baffle thickness too, like maybe the baffle is 6" depth, that'd total a lot less NET/grosse space."
lol it was an example. I've seen some beefy walled baffles, atleast 4", it's not uncommon with cone area exceeding 1000 square inches, you gotta contain the beast!
