OUR PART #  R1810-72-S

Lowell's R Series 15W speaker assemblies are an excellent choice for quality general purpose paging and distributed music applications where economy and installed costs are prime considerations.  The R Series 15W assemblies are comprised of a factory assembled 8" dual cone driver (Model 810) with a dual voltage 25V/70V transformer, an optional volume control feature with screwdriver adjustment in the center of the grille, and a WB-8 mounted speaker grille.

Speaker/transformer assemblies are manufactured to assure consistent performance with clear intelligibility and wide dispersion.  The dual cone Model 810 driver has a power rating of 15 watts RMS and employs a 10 oz. ceramic magnet.  The cone is molded of a high fibre content material to provide a smooth, extended frequency response and a clean, natural sound. To facilitate a variety of distributed applications each assembly includes a dual voltage 25/70V transformer with 0.5, 1, 2, and 4 watt taps.

Architectural grilles are made of precision-formed steel with an attractive white finish to assure a clean presentation of the speaker assembly in a variety of decors and environmental applications.  Grilles include white mounting screws for attractive installation.

A screwdriver-adjustable style volume Control Option for on-the-spot speaker level control is available factory mounted in the center of the grille.
