Theory Audio Design SR-46.2-WH | Quad 6.5-Inch High-Output Loudspeaker White

The Theory Audio Design SR-46.2 is an ultra-slim, high-output two-way loudspeaker engineered for professional sound reinforcement, luxury private cinemas and demanding architectural audio installations. Combining four 6.5-inch low-frequency drivers with a carbon fiber coaxial midrange-tweeter, the SR-46.2 delivers exceptional output and remarkably uniform sound coverage from an enclosure measuring less than 7.5 inches wide.

Unlike conventional loudspeakers with different horizontal and vertical dispersion patterns, the SR-46.2 features wide conical coverage that maintains consistent tonal balance throughout the listening area. This design makes it particularly effective in acoustically challenging spaces, where reflected sound plays a significant role in overall listening quality.

With 1,200 watts of continuous low-frequency power handling and up to 132 dB peak SPL at one meter, the SR-46.2 offers the dynamic capability required for large entertainment venues, live performances and high-performance home theaters. Its slender profile also makes it suitable for installations where traditional sound reinforcement loudspeakers would be visually intrusive.

Built to order in the United States, the SR-46.2 is available in black or white, with passive and self-powered configurations. Optional custom paint, weatherization for the passive version and versatile mounting accessories allow it to accommodate a broad range of residential and commercial applications.

Wide Coverage and Architectural Flexibility

The SR-46.2's conical dispersion is particularly valuable in spaces where uniform sound coverage is essential. Its symmetrical horizontal and vertical coverage allows the loudspeaker to be installed in portrait or landscape orientation without fundamentally changing its intended coverage characteristics.

In theaters and entertainment venues, this helps deliver consistent sound to listeners seated across the room, including elevated seating and balcony areas. For live performance applications, the SR-46.2 can also serve as a low-profile stage monitor, providing wide coverage for performers moving across the stage.

Its narrow cabinet and flexible mounting provisions support installations in visually sensitive environments. Optional Theory SplitYoke brackets accommodate wall, ceiling and floor-monitor configurations, while integrated suspension points and pole cups expand its use in portable and permanently installed sound systems.

The passive SR-46.2 requires two compatible Theory loudspeaker controller channels for bi-amplified operation and model-specific DSP processing. An active configuration is also available.
