TPL150 2.5K Crossover schematics?

Are you aiming for flat response or will you EQ things down afterwards, in other words, do you mainly need overload protection?
If the first applies: it isn’t that simple. You can’t take some crossover from the shelf and assume it turns out right. And honestly, if you’re willing to spend big money on these drivers, any attention to crossover and enclosure design seems mandatory to me.
