( ^ is a reply to1) Which budget 100~150 W amplifier can drive this speaker well? You won't mean Fosi V3: it's been reported that it can't drive the woofer well, it's anemic, and it has load dependence. Which other? 400€ hypex NC12MP? No, it doesn't sound good, treble sounds damn metallic, I tried it. A 45W Onkyo sounds better, more realistic. Cheap class D doesn't have good tonality from midrange to high frequencies. Measurements can say whatever, you listen to real sounds, not pulse sweeps.

1) Needs deacent 100~150 W amplifier that's available even on budget for more than 20 years now.
2) tweeter response is what it needs to be, if you want cheap excitement this is not for you.
3) really take a look at measurements... )
I just started scrolling back a little in this huge topic, so I guess I already have my answer?
