I’m wanting to put 6 12s in a 9 cu ft ported box. How would I got about finding the dimensions of it
Many 12's are like 80 in^2 or so and many 15's are like 120 in^2 or so (Sd-usable radiating area). 6 * 80 = 480 roughly, 4 * 120 = 480 roughly. Depends, there are quite different cone or radiating sizes (Sd in t/s parameters) for the same diameter woofers, especially adding up net Sd with multiple woofers. 6 12's might be more motor and more efficient usage of box space, depends on exact woofers. You can tend to fit more cone area in less space with 12's and more motor.Six 12's give you roughly 628 sq inches if cone area whereas four 15's will give you roughly 706. Why not consider four 15's instead!
Sub-stantial (pun intended) price to performance consideration for sure.
Go big or go home! Couple of Si 24's, just saying...Many 12's are like 80 in^2 or so and many 15's are like 120 in^2 or so (Sd-usable radiating area). 6 * 80 = 480 roughly, 4 * 120 = 480 roughly.

Totally agree, not as simple as just picking most amount of cone areaMany 12's are like 80 in^2 or so and many 15's are like 120 in^2 or so (Sd-usable radiating area). 6 * 80 = 480 roughly, 4 * 120 = 480 roughly.

Okay, maybe 16, 8's? Never said it was that simple, just an option.Totally agree, not as simple as just picking most amount of cone area
Yes lots to consider, entirely possible 4(15)’s could be less money, less amplifiers, more effective cone area, less box dimensions.Okay, maybe 16, 8's? Never said it was that simple, just an option.
One is not better than the rest, sometimes it comes down to simplicity. Any are fine, just an option. I'm a musician too and one of the best BASS cabs that Ampeg offers is their 8x10, largely because of cone area and quickness for a given size cabinet - size does matter. Many also opt for a single 15 with the 4x10 too, all good options, for bass (guitar) playback. Look at McCartneys Mesa-Boogie setup, BIG drivers. More cone area in the same cabinet equals more air moved - all other aspects (model brand, Electro-mechanicals) being equal.
Price starts to be a consideration too. Generally speakering (ha) and six 12's may cost you a lot more than four 15's. etc. Again, it's all good.
Well, you know how that is. Growing up my father would refer to it as a "bug up ones arse", get the bug, you're an arse until it's satisfied! As a kid growing up in San Diego, I got it in my head that I could fit (6) 8" Phillips woofers in the package tray of my Mazda Rx 2 - which after demolishing any semblance of that package tray, I eventually did!Yes lots to consider, entirely possible 4(15)’s could be less money, less amplifiers, more effective cone area, less box dimensions.
Dimensions for a 9’ cubic box for (6) 12’s with no other details is an odd question to begin with.
