What subs work well in 4th order boxes?

[Oldbass38 10+ year member]

I have been told that subs with a lower FS (30's and lower) work best. So, I now need to know what brands/models have been proven to work well in 4th order boxes.

generally subs that work in a sealed box will work well in a 4th order alignment. For standard listeners a higher q low fs woofer would be the way to go.

Like said before, sealed box woofers work well in 4th orders...you can make almost anything work with the right alignment, but a high qts/low fs woofer is best in most cases.

I have used a few for customers and the results were extremely impressive. What gives you this opinion?

Because I'm not super familiar with what an actual high qts or low fs number would be, can you say what range I should look for? Example: qts higher than xx and fs lower than xx...

I'd say qts at .5 or higher is optimal, fs should be 35hz or lower in most cases. The Mach 5 IXL made for sealed boxes looks like a good candidate, as does the high qts version of the Fi Q.

Perfect! Thanks....Now I just need to find a lot of brands that fit that and read reviews!

I plan on doing a pair of IXL 18s in the wagon, 4th order with a cresendo 3k at .5 should be a nice daily driver
