[QUOTE="nineballsafety8, post: 3645244, member: 583462"] not that im saying you don't know what you are talking about, because you are a senior member and have seen your name quite a few times in intelligent discussions on forums here before however... with pressure levels of upwards of 170db inside a ported enclosure what makes you think the the stress on ANY wall would be any less than any other... its basic physics... true SPL is based on atmospheric pressure, not volume... and the number of atmospheres within a port enclosure remain constant through out the enclosure with the exception of about a 30% at corners due to standing waves within the box... ( a sphere is the only enclosure to truly eliminate atanding waves within an enclosre.)... and any way, the double thick port walls are more to support the face of the enclosure that holds the drivers than the "make the ports stronger"... the bracing is set in the enclosure to minimize turbulence... so there are not any braces that run perpendicular to the venting voice.
