Ce haut-parleur est un excellent boomer pour une enceinte 2 voies, C'est également un haut-parleur médium de haute qualité dans des enceintes 3 voies.

I think EXCELLENT BOOMER wouldn't be a bad description of this driver in a reflex-box !

I think this driver is for open-baffle guitar use or something. As said you need to lower Qts by negative impedance, or use a sealed box and Linkwitz Transform.

Personally I would just get a more suitable driver.
