[QUOTE="mlstrass, post: 3467720, member: 569126"] In the original post about the 4" PVC vs a 4" aero and the gain of 7dB is it possible that a 4" port was not enough for the box tested, so by going to an aero which offers more airflow he wasn't choking the box as much and saw the big gain? Sorry for the long *** sentence... Back to the original topic, is it pretty much accepted that by using aero's you can use 1/2 the normal required port area? If so then I could see the advantage to using them over a slot port, even for some daily boxes where the port can ending up taking up a LOT of box space. I've only built one box with an aero, it was 4.25^3 @ 26Hz for a single 15" Tempest. It used a single 4" aero and had NO port noise, was very musical, and got surprisinly loud. This was a copy of the infamous "magic box" from a few years back on CSO when the Tempest was all the rage. I sold the box/sub for $80 to some girl and now and then I hear from her about how her friends are amazed at how it kills their dual 12" set ups from BB/CC and it's a no name sub...LOL [/QUOTE]
