Product Details Quick Overview When applied to vertical surfaces the Dayton Audio DAEX32Q-4 dual spring balanced exciter has more linear movement to deliver extremely accurate response while producing lower distortion. Product Highlights Dual steel spider design to better support the large neodymium motor 32 mm two layer voice coil for high, 20 watts RMS, power handling Pre-applied 3M? VHB? adhesive for quick, secure installation 4 ohms impedance to make the most out of small class D amplifiers Product Manuals / Spec Sheets / Downloads Dayton Audio DAEX32Q-4 Specification Sheet AddThis Sharing Buttons Share to FacebookFacebook Share to TwitterTwitter Share to MoreAddThis 1 Product Description The DAEX32Q-4 from Dayton Audio can turn most rigid, flat surfaces into a speaker. Designed specifically for mounting to vertical surfaces, this exciter uses a dual spring spider to better support the large neodymium motor providing improved linearity. With a 2-layer 32 mm voice coil, this exciter can handle up to 40 watts peak for high output even when attached to thicker surfaces. 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! This exciter is perfect for turning whatever you can imagine into a speaker such as cabinet doors, monitors, windows, garage doors, ect? Note: An exciters frequency response and sensitivity are completely dependent on the exciters 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. Specifications: ? Power handling: 20 watts RMS, 40 watts peak ? VCdia: 32 mm ?
