      Dayton Audio DMA90-4 3-1/2" Dual Magnet Aluminum Cone Full-Range Driver 4 Ohm

       

      Providing high efficiency with low distortion, Dayton Audio's DMA90-4 3-1/2" aluminum cone full-range is an ideal driver for use in many of today's modern speaker designs. Whether you are designing a portable Bluetooth speaker, sound bar, compact desktop speaker, or even a high output line array the DMA90-4 is the perfect full-range for the job.

      Designed for the highest performance while delivering maximum value, the no compromise design of the DMA90-4 produces true full-range output capability with minimal distortion. The motor uses dual neodymium magnets creating a strong and symmetrical magnetic field providing high efficiency with excellent cone control. The magnet assembly also includes a large copper cap and sleeve to lower inductance and distortion resulting in improved high frequency response. The 2-layer 1" voice coil is wound on a vented aluminum former providing excellent heat dissipation for high power handling and low power compression. A rubber surround and large spider keeps the lightweight aluminum cone linear with superb mechanical damping. In addition, the aluminum dust cap is attached directly to the voice coil former to improve high frequency response with terrific off axis performance. Holding everything together is a proprietary 12-spoke frame with an extremely open design that has extensive venting under the spider and ample room for high excursion.

      Furthermore, Dayton Audio designed the frame for all the DMA Series with DIY speaker builders in mind. The oversized mounting flange means that no precision cutouts are necessary. To ensure an easy installation, the terminals are oriented in such a way that no odd cutouts or notches are needed for connector or wire clearance. Finally, the corners have a 1/8" radius, meaning that for flush mounting you can get a perfect fit using any standard 1/4" straight cut router bit.

      Great driver! I have them mounted in a pair of vented enclosures and I am super happy with the result. Very detailed mids and highs, the clarity drops a bit off axis but still sounds good. Bass goes pretty deep and is good enough without a subwoofer for all the music I listen to (except perhaps massive attack). This was my first build and it turned out better than I could ever hope for.

      Excellent product. Great sound. Easy to fit. I purchased the DMA90-4 as a replacement for the central speaker in my new Honda e Advanced model. A great car. With a supposedly improved amplifier and 8 speaker system. I hate to think what the base model sounds like. Thus replaced a standard 3” driver. The DMA really lifts the sound and allows the other speakers to work better. Replacement of the sub next on the list. Shipment costs quite high. But otherwise a very good price.
