tbake223 Posted June 28, 2012 Report Share Posted June 28, 2012 (edited) Back to the drawing board for me guys. ive heard all kinds of things for many people on box design, many things contradicting. After looking through many different builds and doing research this is the box style i came up with, almost a T-Line style slot port. Are my numbers right to consider 3 common walls when computing this? Ive also heard to stay at 1.25 cubes for my 10 and ive seen some people running 2 cubes, i guess im shooting for 1.5. Decided to tune low at 32 for daily driving. Next thing is port area per foot, not sure what the SXX like but ive got 22 mm xmax to play, people say 12-16 but all the pros say 16-20 and to shoot for 20. Throwing in an extra baffle for rigidity and 45s on the port and rounded the ends off. Re SXX 10 sub is 1000 rms, pushing 1100ish rms with my hifonics 1200.1 to it at 1 ohm. Going into a ford focus hatchback Green light to build?!

john253a Posted June 28, 2012 Report Share Posted June 28, 2012 Just refined what you were trying to do, When you use torres to do this style box you need to fill it out like so (the -0.1 is the piece in front of the port opening) Quote Link to comment Share on other sites More sharing options...

tbake223 Posted June 29, 2012 Author Report Share Posted June 29, 2012 (edited) what would u recommend doing? not to mention, today i could heard some strange noises maybe from my VC might be in the market for a new sub already and dont even have this built yet! haha Edited June 29, 2012 by tbake223 Quote 02 Ford Focus ZX3 hatch 4-Infinity Kappa 682.9cf's DC Lvl 4 Hifonics BRZ 1200.1 @ 1 ohm Kicker Wires Rockford RCAs Future Upgrades Knu 1/0 XS Power D1200 80 mil audiotechnix B stock Link to comment Share on other sites More sharing options...
Joe X Posted June 29, 2012 Report Share Posted June 29, 2012 That folded port may not be the most efficient due to all the turns, I would give some more port area than I would do to a simple L shaped port to keep airspeed low. Quote Link to comment Share on other sites More sharing options...

How come people like T-Line boxes? as long as theres no bottle necks in the bends of the port i thought this design would be better, not for sure tho Quote 02 Ford Focus ZX3 hatch 4-Infinity Kappa 682.9cf's DC Lvl 4 Hifonics BRZ 1200.1 @ 1 ohm Kicker Wires Rockford RCAs Future Upgrades Knu 1/0 XS Power D1200 80 mil audiotechnix B stock Link to comment Share on other sites More sharing options...
john253a Posted June 30, 2012 Report Share Posted June 30, 2012 Do be confused between a ported box and a T-line, your box you designed is a STD ported box A T-line is normally cone area in sq" of port and length of 1130/hz /4 for 1/4 wave So for a 10" it would be some where in the 70sq" port 96" long at 35hz Quote Link to comment Share on other sites More sharing options...

Please show us how with a sub up port back and more port areo Yes it not the most efficient design. But works within the size given And I don't think more then 22sq" of port is required for a single 10 Even with that port Edited June 30, 2012 by john253a Quote Link to comment Share on other sites More sharing options...
tbake223 Posted June 30, 2012 Author Report Share Posted June 30, 2012 i know its not a t-line per say but they do have similar qualities, i didnt know it was known as an STD style. So go L shaped port i take it?
