How come external crossovers are not more popular ? Seems like easy access for tweaking.
It would be a cool way to do upgrades too. Imagine building a Fusion 12, but wire up each driver directly to the speaker binding posts on back of cab and the. Just buying the external external crossover and hooking it up. Then later adding a second 12 mid bass module as an add on to do dual 12". Or expanding to be a three way with second 12" and mids. An external crossover would allow you to just stack that second upgrade on top of the first and swap out crossovers. Some minor attention into the box design so the distances from the upgrade drivers to original might be needed up front though.
