Lowell Manufacturing ES-4T 4" Dual Cone Speaker, Transformer, Enclosure, Grille
ES-4T produces excellent intelligibility for speech and full-frequency response for music making it ideal for retail, commercial, industrial, institutional and residential applications. This self-contained in-ceiling or in-wall speaker system with 4" dual cone full range driver has a high-frequency whizzer cone to provide the kind of crisp, high-frequency response that would typically only be produced by a coaxial speaker. The ported enclosure is tuned for extended low-frequency response, while the speaker's wide dispersion can actually reduce the number of speakers required to produce even coverage in distributed speaker systems. Driver 4" dual cone driver with high-frequency whizzer cone. Transformer 16W transformer with tap selector switch mounted behind grille. Tap selections for 25V, 70V or 100V speaker systems and 8 ohms transformer bypass position. Enclosure Factory-mounted enclosure ships attached to the driver (non-removable) Durable 20 gauge steel, painted gray Ported enclosure is tuned for extended bass response Built-in reversible mounting dogs aid fast installation, while allowing the speaker to be mounted in drywall, wood, tile or almost any type of ceiling with thickness up to 2.125" Removable (4 pin) Phoenix-style connector with 2 terminals for input to speaker and 2 parallel terminals for output to next speaker in string Internal volume = 113 cu.in. Baffle Low-profile front baffle formed from UV-rated high impact plastic. Grille Fine mesh press-fit grille (white) includes scrim and pull tool. Installation Aids: (included) C-Ring Reinforces the edge of drywall ceiling cut-outs and works with the support rails to uphold the weight of the speaker assembly. Support Rails (2) Rails are used with the C-ring to uphold the weight of the speaker assembly and help prevent sagging tiles when the speaker is installed in a lay-in tile ceiling. Template Paper template is used to properly mark cut-outs for mounting holes. Paint Shield Plastic shield fits over the driver to protect it if the baffle is to be painted.
