Are you saying that with the AE, I can break the 3x Vas rule? I have a vw cabrio with a 7.6 cubic ft. trunk...that is beggin for this sub if that is the case. Do you think that it would work?Imo you don't actually want a true IB sub. The AE is optimized for a car trunk. Real IB subs can require several times that volume especially in 15 and larger sizes. Besides the AE has lots of motor goodies.
I would say only below your tunning frequency (30hz you say?) or above 70hz or so where thermal becomes more important.Would 2 15's equal the in car output of a single 15 in a ported enclosure?
Just test at a different frequency. If he runs ported test below his tunning frequecy. If he runs sealed test at 100hz. You see where this is going. With any competition if you want to have the best chance winning you want to have the winning design. It's not likely that's the lowest weight, or the best sounding. IB is a best all around solution for the car environment unless you have a minvan or hatchback. However, unless you are going for thermal tests at high frequencies it's not going to win you any trophies.Plus, with the teenager son rapidly approaching a louder vehicle than mine, I have to stay at least competitive.I will have to seriously ponder this.
