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.
