TOA SR-S4S Slim Line Array Module Curved 600 W 8Ω White
Product Details
The TOA SR-S4S is a Type S line array module: eight 10 cm woofers and twenty-four 2.5 cm dome tweeters in a 160 mm wide cabinet, 600 W continuous program at 8 ohms, with 90 degree horizontal dispersion. A line array works by stacking drivers vertically in close proximity so they behave as one tall sound source rather than several separate ones. The result is tight vertical control: sound goes to the audience and not at the ceiling or the floor, which is what keeps speech intelligible in a room with hard surfaces and a long reverberation time.
The L and S suffixes are the coverage pattern, and they are not interchangeable. L is straight — 0° vertical, a flat wall of sound within the height of the cabinet, for throwing down a long room. S is curved, spreading the pattern vertically to cover an audience closer in and across a wider depth. This one is the S version — vertical coverage 10°. The straight L model is stocked as SR-S4L. TOA quotes the frequency response with the optional DP-SP3 digital speaker processor applied. Without it the speaker still works, but the published figures assume that processing is in place — worth factoring into a system design rather than discovering afterwards.
This is the standard indoor version, MDF with a painted punched-steel grille, terminated in an M4 screw terminal and two Neutrik NL4MPXX connectors so it can be run single-amp or bi-amp. For an outdoor or under-eave position order SR-S4SWP instead — plywood and stainless steel, with a permanently attached cable — and its matching WP brackets. Mounting options: SR-FB4 flying | SR-TB4 wall tilt | SR-SA4 stand adapter | SR-EP4 extension plate.
