Bought this as a small subwoofer to pair with some small bookshelf speakers I built with 3" full range tang band drivers. I have built and owned many speakers and this driver still surprised me. I was hoping for a bit more low end, comparable to your average bookshelf speakers, and paired with a 5-1/4" passive radiator and a 25 watt amp, this thing is a legitimate subwoofer. I haven't measured it, but I would put the frequency response of my setup, in an enclosure that's only about .25 cubic ft, to be around 40hz. Very impressive for such a small driver.

Ce modèle de haut parleur ND91-4 est vraiment très performant pour sa taille et son prix et mérite 5 étoiles. C'est le second que je commande et ça manque cruellement de renforts en polystyrène niveau packaging... C'est triste, ce beau petit HP mort écrabouillé pendant le transport, voir photos. Au moins on a une belle vue éclatée de la voice coil et du système magnétique avec sa bague de démodulation en cuivre. Je repasse en 5 étoiles quand le vendeur m'aura envoyé le produit.

Ce HP large bande a une bonne réputation aux USA, mais il manque cruellement d'aigües - au-delà de 6-8000Hz la baisse est trop rapide, alors que pourtant il est capable d'une belle netteté si on équalise un peu en préamplification. Ou alors il faut lui adjoindre un circuit de compensation, ce qui enlève tout intérêt à ce type de HP qui est fait pour du câblage direct, sans filtre. Pou les basses, c'est surprenant de voir ce qu'une si petite membrane peut produire. Pour peu, encore une fois, qu'on l'amplifie ou filtre correctement et qu'on le place dans un volume suffisant pour ne pas l'étouffer. Adjoindre un bass-reflex ou ligne de transmission peut améliorer les choses mais attention à ne pas vous planter dans les calculs de volume et de longueur de ligne. Un si petit HP ne rentre plus dans les normes des softs de calcul... Bref, beaucoup de potentiel mais difficile à maîtriser. Attention à la faible puissance, amplifier avec prudence...

Beautiful! Used for my custom Bluetooth speaker. Mount front or rear, comes with extra gasket.

They make surprising amounts of bass for such a small speaker.
