UL Listed Wide-Range Paging Speaker 30 W 70.7/100 V Transformer

The TOA CS-304U is a UL Listed wide-range paging speaker built around a 30 W rating and a 70.7/100 V transformer. Identified by TOA as part of its Wide Range Horns product category, this model is intended for paging applications that require compatibility with either of the two stated distributed-line voltages. Its focused specification makes it straightforward to evaluate when a project calls for the CS-304U model specifically.

Ideal Use Cases

The CS-304U is suited to paging systems based on a 70.7 V or 100 V speaker line. Its transformer supports either stated voltage, allowing the model to be considered for projects designed around one of these common distributed-audio formats. The 30 W rating provides a concrete reference for system planning and amplifier-load calculations. Because no application environments or mounting locations are identified in the supplied information, suitability for a particular indoor, outdoor, commercial, industrial, or institutional setting should be confirmed against the requirements of the installation.

Why Choose This Model

This model brings together four clearly identified characteristics: TOA product identification, a wide-range paging-speaker design, a 30 W rating, and a 70.7/100 V transformer. It is also described as UL Listed. These details give system designers and buyers specific criteria for comparing the CS-304U with the requirements of an existing paging system or a new design. The shared model, manufacturer part number, and SKU designation of CS-304U also helps reduce ambiguity during specification, purchasing, and replacement planning.

Installation and Integration

Integration should begin by confirming whether the paging amplifier and speaker circuit use a 70.7 V or 100 V distributed line. The CS-304U transformer is identified for both voltages, but the supplied product data does not provide terminal assignments, selectable tap values, wiring diagrams, mounting instructions, dimensions, weight, or environmental limits. Those details should therefore be verified before installation. The stated 30 W rating should also be included when reviewing the total connected speaker load and the capabilities of the associated paging equipment. No mounting hardware or included accessories are specified in the available source data.

Performance Highlights

The principal performance value supplied for the CS-304U is its 30 W rating. The product is also identified as a wide-range model within TOA’s Wide Range Horns category, while the listing title describes it as a paging speaker. A technical value labeled “refresh rate” is reported as 120 Hz in the scraped source; because refresh rate is not otherwise explained for this speaker, it is retained only as a source-reported value and should not be interpreted as an audio-frequency specification. Frequency response, sensitivity, impedance, sound-pressure level, dispersion, and transformer tap details are not provided.

What Makes It Different

The CS-304U is distinguished in the supplied data by the combination of dual 70.7/100 V transformer compatibility, a stated 30 W rating, and UL Listed status. This set of attributes enables a precise initial match against projects that explicitly require those characteristics. The product identity is equally clear: CS-304U is the model, manufacturer part number, and supplied SKU. The available information does not state enclosure material, finish, weather resistance, coverage pattern, connection type, or included components, so no additional durability, acoustic, or installation claims are made.

Final Assessment

The TOA CS-304U is a focused option for a paging-system specification requiring a wide-range speaker with a 30 W rating and a 70.7/100 V transformer. Its UL Listed designation adds another clearly documented selection criterion. The source data establishes the model’s core electrical and product identity but does not provide the broader acoustic, physical, environmental, or accessory details needed for a complete installation decision. Confirm those project-specific requirements and installation documentation before ordering, particularly where dimensions, mounting, transformer taps, frequency response, or environmental suitability are important.
