Default Beware of.....

People who think they know what they are talking about but really don't. There is a member on here who has been giving "advice" to some guys I know and designed a box for my teammate and another friend. While building one of the boxes I realized something wasn't right so I ran the numbers and of course what was promised was not what was given. After running the numbers on my teammates box and having others check my work (to support validity) it was found that in fact both designs were wrong.

The first design:
Box meant for 2 icon 10s on two saz-1500s strapped @ 1ohm
Sub displacement (.24 cuft)
what was promised:
2.5 cubes net @ 33hz

what the box actually is:
3.2 net @ 36hz




The second design:
Wall meant for 4 lvl 4 15s on a crescendo 3kw @ .5 ohm
Sub displacement (.84 cuft)
what was promised:
14 cubes net @ 38hz

what the box actually is:
9.5 cubes net @ 44.45hz





As you can see simple math can tell you that even the cubic footage is way off in the second box and slightly off in the first. Then for those who can calculate tuning you can see that tuning is off as well. This really pisses me off because my teammate wasted $200 in materials to build a box that was flawed by a guy who thinks he knows how to design enclosures.
