[QUOTE="Jeffdachef, post: 8563619, member: 650438"] btw [USER=664735]@ferguson621[/USER] my wall is only two layers of ply and some bracing, no flex. Overall enclosure design trumps over trying to overbuild on the box strength. Sometimes you just have to pay for a good design which i gave in and did and it worked out amazing. I would also like to add my stubborn @ss friend with the alphard 6th order wall finally did fiberglass and sealed up the wall from the rear and had massive spl and SQ gains from his bass. Bandwidth just jumped massively from 29-38hz to 25 to 55hz and gained 3 db just from sealing off. OH I FORGOT TO MENTION he gained 3 db after sealing off using a sundown NS-1 vs two alphard 12ks. so yeaaah BIIIIG fking difference He really didnt understand the importance of making a proper seal and what it can do for your score. you basically cant have any sliver of air going backwards towards the rear at all. I would also like to say that his build was overly emphasized on strength with a steel cage and everything but at first was a complete and total flop due to his hard headedness and lack of any attempt at sealing the wall up along with bad specs from Alphard. Box strength only does soo much, you get massive diminishing returns after a certain point. [/QUOTE]
