I built the box exactly as JL specified for this 10"W6v2. I had it mounted normally (magnet in box) for a while but was getting unusual distortion at 2/3 output. Took the woofer out, ran it outside the box, played fine if the backside of the woofer (where the emblem is) was not touching (or close to) a surface (some kind of venting technology). So I figured the clearance was wrong inside the box (even if im 100% sure the box was exact to their specs). So I thought about old friends I had heard saying down fireing designs were the best. So I figured id try it. Pryed the front board open, flipped the woofer 180 degrees re glued, screwed and sealed the board back into place.

Result: Holy Crap! It sounds so much louder than before and its crisp clean and tight. I have the gain on my JL 1400d amp all the way up, boost on and I only pick up some distortion at around 90% volume on deck. I have one tiny air leak somewhere but im in the process of finding it (explanation for the orange silicone rubber). Soon as thats done Ill fasten the carpet back.

So, anyone ever try this before? What were your results?

Lemmy know

Thanks

yeah thats like making a bass tube i have done similar stuff but with tubes not boxes

I used to have a rs an I had the pre made well box that sat flush with the deck I had a cheap 100 watt amp an 2 12" mtx thunder 4000 s I didn't like the sound with them face up so I flipped them an d I loved it I left it like that for the two years I had it

Acoustically there is no difference between the speaker positioned with the magnet inside the enclosure as opposed to outside. The only difference when doing this with no change to the enclosure itself is that there will be more enclosure volume with the speaker positioned with the magnet out, that will allow for some extension into the lower frequencies, usually at a sacrifice of power handling.

Some people say there could be more mechanical "noise" or "distortion" with the
magnet out, due to the speaker mechanicals and suspension being exposed.

Physical location or direction of the speaker won't change how it sounds, what can change is loading, and distance from the speaker to your ear that can change how a speaker system sounds, but if the distance from the cone/voice coil to your ear remained constant, without a change in loading (i.e. corner loading), then there will be no perceivable difference in sound.

When you friends were refering to "downward firing" I would suspect they meant with the speaker locate in a way that used the floor for loading, much like many home theater type subwoofer systems. Again physical direction of the speaker itself will mot change how it sounds.

So you have to actually break the enclosure to change the speaker? If so, why didn't you just flip the speaker over and mount it way?
