my 4x12 marshall slant cabinet idea has been largely calculated, and without making this an essay long, let’s just say that with all the obstructions and all of that being factored roughly into the final results for my volume per speaker findings, i’ve finally almost reached the end. but another problem has come up, though the problem shows that i’ve made progress. at the top of the cabinet, the area with the least volume, the volume per speaker is roughly 1.16 cubic feet. at the bottom of the cabinet, the straight section, the volume per speaker is roughly 1.76. that’s quite a difference, as one would expect, but that’s not all there is to it. the speakers i’ll use are eminence beta 12a speakers, and their volume per speaker recommendation is 0.9 to 1.25 cubic feet. the top of the slant checks out for that recommendation, but the bottom is too large. is this a problem?? will the two speakers make different noises and be competing with each other? can i add volume to the bottom section of the cabinet without interfering with the top of the cabinets volume? below is an image of the cabinet interior (listing). also an image of the total cabinet volume, because that’s useful. it’s not separated from top to bottom, but i did the top and bottom calculations because they’re basically different enclosures for each set of speaker and it was important information to know. thoughts would be very appreciated!!!
