[QUOTE="Buck, post: 8813701, member: 591582"] I wouldn’t eyeball it. The wrong specs for a 4th BP can really make them sound poorly, and you really have to make sure you have the right subs for the sealed section that’ll play like you want. 4th BP’s have a lot of misconceptions, at least I’ve seen a lot of misconceptions relative to chamber sizes and ratios. The worst way to do it, IMO, is when I see people do a tiny sealed chamber and a huge ported chamber; that’s really more of an SPL style 4th, can be very peaky, not play low, fall off severely away from tuning/peak. Every sub and system situation varies, so if you really want the best sound, it’s best to incorporate all of your system’s specific factors into the design, and make sure a 4th BP is going to meet your goals. The most important part for musical response is making sure the sub plays well in the sealed section, as that is the primary chamber for the entire 4th BP. It’s also important to know exactly what your specs are to learn what those specs sound like this time, so you can know how you can modify those relative specs in the future for new builds. [/QUOTE]
