starter sound system

Hello, i'm very new to sound systems, I wanted to know if art welter's keystone 18" sub would pair well with 2 the box pro Achat 110M, or is it better to make diy tops for a better price, im also not extremely good at woodworking so any more simple suggestions would be highly appreciated. Thank you:)

The keystones have an insane internal height of 1.1 m which means they are resonant at 156 Hz which means you should give them a lowpass filter at around 78 Hz. The Achats are quite good, but they can't keep up when they have to play that low.

You should look for plans from outside the us, since they almost always have that limitation of being big and boomy

Thank you, would you maybe have better suggestions for the tops, and also, I was thinking of adding tham12 later on, and maybe that would solve the problem :)
