Now I still stand by my opinion that dual bandpass boxes are going to be bloated floppy pieces of junk. But thats probably because I worked for best buy from 1999 to 2002 which seemed to be the heigh of popularity for lousy bandpass boxes

Cars have such extreme cabin gain that ported may not be needed unless you want really strong bass. A sealed enclosure with a decent sub may play flat to 20hz in a car, at least that is what perliminary results of cabin gain modeling in WinISD show, tho I haven't researched it extensively yet.

ya prefab BP is pretty pointless, but modeling one up driver/use specific can have great results. I actually hated ported for years and years until I realized if I tuned lower than the norm, I was much happier. I mostly ran sealed but did a lot of 4th orders as well.

Yeah, actually I was just taking a jab at Best Buy shoddy car audio. It might be interesting to try a 4th or 6th order bp someday. But if I do it'll be after I've got the other stuff I want set up and I'll just do that as an expirament to see what its like. It does seem like they would have a lot of group delay tho from having the 2 ports, maybe 4th order is better.

yeah, it's all trade offs... gain vs quality. IDK how well I detect quality anyway. I try to buy linear drivers and have more power than I need to keep the amp in line as well, and I make my boxes large and low tuned. It may still sound bad, but I don't notice if it does.
