SQcomps install

[Alien Mantis]

Strange graph readings.

I would expect to see an amplitude peak around 3 db's higher on that ported box line, around the 40-50hz region.

Every single graph I have ever seen, shows a FLAT curve for a sealed box, with a drop-off starting around 50hz, and a slightly higher peak in db just above the tuning frequency for a ported enclosure.

And why would anyone ever want to run a GIANT over-sized SEALED box ???

Why not save space and just do a ported box?

and Infinite Baffle install is pretty much a giant sealed box. To mimic an IB install using a sealed box you only have to have a box 4 times greater than the vas of the sub.

that isn't an amplitude chart per say, it doesn't show how loud it'll be, only how quickly it'll roll off.

the reason why it doesn't look like the ported box is a lot louder is because it is a small size ported box considering how low it is tuned... That is an extremely low tuning for a car.


I'm trying to convince sqcomp to do something a bit more radical, yet easy on his install... I'd like to see dual 15's IB in his trunk.
