P4killer_ Posted September 8, 2009 Report Share Posted September 8, 2009 So i saw this vid with sonotube used for a single 12" enclosure, and while i have heard of people using tube designs before, ive never seen one on a larger scale. since sound waves like round surfaces i wanted to just whip up a box and see what people think. first my numbers then the pic anyway the enclosure is for (6) 12" woofers. its basically a 40" x 40" cube. with a 40" diameter sonotube secured inside. the cube itself is just for support the cinlinder (sp) itself will be the actual enclosure. obvi the corners of the cube are wasted, possibly fill em with resin or expanding foam... so the cinlinder is 40" dia x 19" deep. the volume is then ((20^2*Pi) x 19) = 23876.10 divide by 1728 = 13.817 Cu. before dis. if my calc is wrong oh well the principle/ idea is the same. so 13.8cu. / 6 subs = 2.3 per sub as for the port, thinking that 12-16 sq in per cu is ok i couldnt fit any number of aero ports to fit so i just went with a 14 * 12 port = 168 sq in of port / 13 cu = 12.9sq in per cu... anyway i dint figure tuning as i just wanted to present the idea of a completely circle enclosure, opinions, ideas, whatcha' think?

Namosh Posted September 9, 2009 Report Share Posted September 9, 2009 I like it. Are you actually going to build it? It doesn't look like it would be difficult. My Ram Quad Cab Blow-through Link to comment Share on other sites More sharing options...
zfrerichs Posted September 9, 2009 Report Share Posted September 9, 2009 your gonna have to try it and i would say fill in the sides with concrete before i would try resin or expanding foam, also i know you said you couldn't get any areo ports in there but why not build you own larger flared port? or use another sonotube for the port, or you could use some sewer piping for the port Roseville, CA Link to comment Share on other sites More sharing options...

P4killer_ Posted September 9, 2009 Author Report Share Posted September 9, 2009 how so? i mean there is alot of waste and extra building req. if using a tube is to save time and material then sure, but would you trust a cardboard tube to hold up six 12's pounding away..... i would not... as i said i have heard of tubes for an 18 or something but never six 12's or anything similar... if im wrong, enlighten me Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...
