wickedwitt: it's all about aligning the subwoofer (pump) perfectly to a suitable box (transmission) to yield the desired result in a specific place in your vehicle. if that weren't the way it worked, then you would hear no difference every time you moved your enclosure around in the trunk and got back in the driver seat to take a listen. fire the subs in one particular direction (with every enclosure) and it'll get louder than the other 20 directions you fired it. fire it in the same direction but move it over 8" and it's gonna sound different. put the same port(s) on the side versus the front and it sounds different even though every spec of the box is identical to the other box. this is because the second half of the enclosure is changing what you've just changed. there are boxes that will make the 10L7 sound tight in one vehicle and sloppy worst than 2nds with the same box in a different car. same works for the 15" or even an 18" and larger.....they will sound sloppy in WAY more enclosures than they will sound great in. align all the factors properly and you will be hard pressed to pass a blind test as to which sub is playing if all are dialed in to the same reference volume.
let me know if that was helpful or no....
