Dayton Audio DAEX32U-4 Ultra 32mm Exciter 20W 4 Ohm

Dayton Audio DAEX32U-4 Ultra 32mm Exciter 20W 4 Ohm Overview:Turn large, rigid surfaces into speakers with the Dayton Audio DAEX32U-4 audio exciter. Includes pre-attached 3M VHB adhesive for maximum energy transfer, even on moving objects! Highlights:Heavy-duty design with a 32 mm voice coil for a high 20 watt RMS power handlingPre-applied 3M™ VHB™ adhesive for quick, secure installationRare-earth neodymium motor and a proprietary two-layer voice coil4-ohm impedance for use with small, Class D amplifiers Product Description:Dayton Audio’s DAEX32U-4 Ultra exciter is built to turn large, thick, rigid surfaces into speakers. The 32 mm voice coil makes it perfect for large glass panes, furniture, and surfaces that would normally resist the effects of an exciter. A neodymium magnet is employed to create maximum magnetic flux around the proprietary voice coil for increased sensitivity when compared to similar sized exciters. In turn, this reduces power requirements and makes it possible to use very small Class D audio amplifiers, without sacrificing total output. To ensure maximum acoustic energy transfer between the transducer and the surface to which it is attached, 3M VHB (Very High Bond) adhesive is pre-applied to the main body… just peel and stick! Two male spade quick-disconnect terminals are built onto the main body for quick electrical connection. Product Specification:Power handling20 watts RMSVCdia32 mmNominal impedance4 ohmsRe3.5 ohmsLe0.23 mHFs160 HzDimensions2.625″ (66 mm) overall diameter x 0.75″ (19 mm) total heightAdhesive dimensions1.64″ (41.7 mm) outside diameter, 0.86″ (21.7 mm)Weight140 grams. Note:An exciter’s frequency response and sensitivity are completely dependent on the exciter’s designated surface. Thinner, smaller materials will tend to be louder and create a mid/tweeter response. Thicker, larger materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.Dayton Audio DAEX32U-4 DataSheet
