The Radio Design Labs 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 spherical 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).

  • Acoustically Optimized Decora Enclosure
  • Fidelity Comparable to Larger Drivers
  • Exceptional Audio Quality for Ultra-Compact Size
  • Rich Presence and Detailed Clarity
