Dayton Audio DAEX25X4-4 Bullfrog Vented Disc Spider 25mmX4 E 295-242

Overview The Dayton Audio exciter assembly's unique design uses four 25 mm exciters coupled to a plastic frame to actuate a larger area with more force than conventional designs. This array of exciters is wired in a series-parallel configuration for an overall impedance of 8 ohms and power handling of up to 40 watts RMS. The DAEX25X4-4 exciter features the same ability to turn nearly any surface into a speaker as other exciters and tactile transducers do, only with a larger contact area and moving mass that increases energy transfer. Perfect for use in walls, drop ceilings, or even cabinet doors. 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... just peel and stick! Connection is made with 10' wire leads to keep installation and wiring as simple as possible.
