Whether you are designing a portable Bluetooth speaker, sound bar, compact desktop speaker, or even a high output line array the DMA45-4 is the perfect full-range for the job.Designed for the highest performance while delivering maximum value, the no compromise design of the DMA45-4 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 0.75\" voice coil is wound on an vented polyimide 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 8-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.Specification: Product DetailsBrandDayton AudioModelDMA45-4Part Number295-580UPC848791005183Unit of MeasureEachWeight0.15Product SpecificationsNominal Diameter1-1/2\"Bolt Circle Diameter1.97Power Handling (RMS)10 WattsPower Handling (MAX)20 WattsImpedance4ΩFrequency Response150 to 20,000HzSensitivity82dB 2.83V/1mVoice Coil Diameter0.75\"Thiele-Small ParametersResonant Frequency (Fs)151.4HzDC Resistance (Re)3.7ΩVoice Coil Inductance (Le)0.3mHMechanical Q (Qms)5.23Electromagnetic Q (Qes)0.62Total Q (Qts)0.56Compliance Equivalent Volume (Vas)0.003ft³Mechanical Compliance of Suspension (Cms)0.83mm/NBL Product (BL)2.8T·mMaximum Linear Excursion (Xmax)2mmSurface Area of Cone (Sd)8.6cm²Materials of ConstructionCone MaterialAluminumSurround MaterialRubberVoice Coil Wire MaterialCopperVoice Coil FormerKapton® / PolyimideBasket / Frame MaterialPolymerMagnet MaterialNeodymiumMounting InformationOverall Outside Diameter1.81\" x 1.81\"Baffle Cutout Diameter1.57\"Depth1.02\"# Mounting Holes4Parts Express Staff Recommended Enclosure VolumeSealed Volume0.01ft³Sealed F3220HzVented Volume0.014ft³Vented F378HzManuals & Resources: Dayton Audio DMA45-4 Zip FileDayton Audio DMA45-4 SpecificationsDayton Audio Manufacturer Warranty 10904306 848791005183 0.1500lbs 0.00 0.00 0.00

I originally purchased to replace the speaker in my Echo Dot 3, but it’s too large. However, it did turn out to be perfect for arduino projects.
