Does the shape of the box effect the preformance of the sub? (ported)

I havent delt with any sort of box besides Square and Rectangular...

Example Triangle?

Round is best, let it roll around...

LOL im not building a round box...

Im just wondering because sound travles differently with the way that it bends around curves and stuff....so wouldnt a differently shaped box affect the sound? and output? or no?

Yes, anything you do to sound waves changes it slightly. Start building boxes and measure sound pressure to the smallest scale you can. Tell us what you find.

I hear that putting sand in the box helps is this true?

No, they found out sand isn't a direct replacement for SPL dust.

I can tell that any questions I ask here will never be answered corectly...

I told you do the round box... n00b.

Yeah he told you a round box, the discussion was over.

The only good bet is a tear drop shape or a cone.

what about star-shaped?

I liked my uniquely shaped box i made once. it got a lot of comments on how well my wood was formed, the feeling of my wood was soft, the fuzz on the bottom was well maintained etc etc. I swear between the vibrations it put out and the smoothness it was a real weiner:D.

what about star-shaped? I think the less harsh corners the tighter the sound so I wouldnt go with a star, too many hard corners. If you look at the SPL boxes they seem to even round the inside corners of the 90degree angles by putting an inverted triangle in the corners.

i wasnt being serious by the way ;)

yeah that'd be called a backwave board bud;). it's amazing what wave alignment and backwave cancellation can do for an SPL score:). So far I don't think anyone's response has been remotely serious.

To the thread starter, as stated the more sharp corner's a sound wave has to travel around the lower your SPL, keep it simple, smooth, well braced, and sealed(not a selaed box but no air leaks).

the less amount of parallel planes, the less chance for standing waves....

I was looking into doing a Triangle shapped box... (90 degree trinangle... with the L shapped side against the back of my seats... and the angled side aimed toward the back of my tailgate (that is where the sub would be... and the amps)
