Enclosure Tuning?

What exaclty is involved with tuning a box? Is it the wood, the volume, the shape, ports, or just the speaker? Thanks

it's a combination of all of thosewhat!?!?! you want some??

i'd like to know this too, cuz i dont feel like paying 300 bucks for my shop to build my ported box for me. If you pros out there could give a little advice or tips on how to tune this, you'd be saving me alotta money. thanks. 1990 Honda Civic HB:

IT ALL DEPENDS ON WHAT TYPE OF BOX YOU WANT TO BUILD.  PORTED ENCLOSURES ARE TUNED MAINLY BY THE PORT, SEALED ENCLOSURE ARE TUNED BY AIRSPACE AND PLACEMENT. FOR A PORTED ENCLOSURE YOU NEED TO BUILD A BOX TO RECOMENDED AIRSPACE, THEN TUNE IT TO A CERTAIN FREQUENCY WITH THE PORT.  SEALED IS A LITTLE MORE DIFFICULT, I DON'T REALLY KNOW ALL OF THE TUNING ABILITIES OF SEALED BOXES, I JUST BUILD MINE TO THE RECOMENDED AIR SPACE FROM THE FACTORY AND IT SOUNDS FINE TO ME, BUT I KNOW THERE IS A WAY AND FOR SQ THEY TUNE BOXES TO THE "Q" OF .7 OR SOMETHING LIKE THATwhat!?!?! you want some??
