RDL D-SP1A 2 Watt Decora-Style 8 Ohm LoudspeakerFeatures: Acoustically Optimized Decora Enclosure; Fidelity Comparable to Larger Drivers; Exceptional Audio Quality for Ultra-Compact Size; Rich Presence and Detailed Clarity; Hemispherical Dispersion Mounted In Wall or Flat Surface; Convex Aluminum Cone with Rubber Surround; Neodymium Motor; The D SERIES-SP1A is a compact 8 ohm loudspeaker that delivers rich, detailed sound in Decora-compatible wall or chassis mounts. The driver is constructed of materials found in premium larger speakers. The unique steel enclosure provides full baffling in a tightly sealed rigid structure. This produces sonic presence within an extended frequency range expected from larger speakers. Internal filtering rolls off out-of-band frequencies to reduce distortion and increase peak power capability. Dispersion covers a hemispherical area of nearly 180 degrees with the speaker mounted in a wall.The input is connected through a 2-position detachable terminal block on the rear panel. The D SERIES-SP1A operates with a continuous audio input up to 2 watts, making it suited to be driven by speech or music content from amplifiers with a maximum rated power of up to 10 W. Models are available with grills in black (DB-SP1A), white (D-SP1A), gray (DG-SP1A) or stainless steel (DS-SP1A).SpecificationsInput Power: 2 W RMS (modulation peaks limited to 10 W)Input Connection: Detachable terminal block (14 to 24 AWG)Impedance: 8 Ohms (nominal)Frequency Range: 150 Hz to 20 kHz, nominalSensitivity: 78 dB (1 W, 1m nominal)Enclosure: Powdercoated steelGrill: Formed perforated steelDimensions: Height: 4.1 in. 10.4 cm; Depth: 2.07 in. 5.26 cm (with terminal block); Width: 1.72 in. 4.37 cmMounting: Mounts in US electrical box, RDL international wall boxes WB-, surface mount box SMB-, or desktop chassis' DC- available separately.Mounting Box Minimum Depth: 2 in. 5.08 cmPackage Type: Cardboard BoxPackage Dimensions: 3.625 x 4.625 x 2.125 inShipping Weight: 0.53
