Why people hate 4th orders?

[QUOTE="VWBobby, post: 8357630, member: 624844"] The main reason you don't see more people doing them is the complexity of the design compared to a standard ported or sealed box. You want a ratio of around 2:1 (ported section being twice as large as the sealed section). As said before, if done right, the output really can't be beat. If you are going for a narrow bandwidth such as SPL, bass music, etc...it could work out well for a lot of people. A quick 4th order design in WinISD will show you how much more output the same woofer and power will have compared to ported. Play with the ratios of the chamber sizes to see how much output you can get when narrowing the band (tuning). Some speakers respond better than others in a 4th order, but generally not as picky as ported compared to sealed. [/QUOTE]
