## Overview

The Dayton Audio ND91-4 is a high-performance 3-1/2" full-range driver designed for audiophiles seeking low distortion and a wide frequency response. With its robust aluminum cone and advanced motor structure, this driver delivers exceptional sound quality and reliability, making it an ideal choice for both DIY projects and professional audio applications.

## Description

The low distortion and high excursion capabilities of the Dayton Audio ND91-4 3-1/2" full-range driver make it an ideal candidate for miniature point-source monitors, surround speakers, and line arrays. When teamed up with the matching ND series passive radiators this driver can produce incredible full sound from compact enclosures.

Review: 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.
Review: 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.

*by B***L on 6 October 2017*

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...
