Lowell LUH15T
70v Speaker


The LUH-15T is a ‘Universal Use’ 15W re-entrant horn in a compact 3.361"D size. The attractive package includes the cast aluminum horn with aluminum trim ring and press fit grille for no visible hardware providing an architectural solution for anywhere an environmentally resistant high intelligibility speaker is specified.

It installs indoors or out, using adjustable clamps or screws with or without a 4"D backbox in recessed or surface applications. Although a grille is included, the UNIHORN™ will accept a standard 8" screw-mount speaker grille and backbox if desired. Simple 2-wire hook up, dual capacitor circuitry, and 105dB SPL (1W1M) make this horn ideal for standard or supervised paging/signaling applications. Connections are made to a rear metal clamp and the 25/70V transformer is screwdriver adjustable on the front and rear. Finish is Network Grey powder epoxy. Weight is 6 lbs
