Indoor 1' x 2' 8O Suspended Ceiling Mount Extension Speaker

Ideal Use Cases

The AtlasIED IP-12SYSP is an indoor 1' x 2' suspended-ceiling passive speaker designed to expand announcement and background music coverage in large spaces. Its rectangular ceiling-mount format is suited to projects planned around 1' x 2' suspended-ceiling locations. The specified 120° horizontal by 130° vertical dispersion provides a broad coverage pattern, while 95dB SPL sensitivity and a calculated 105dB maximum SPL at one meter provide concrete output references for system planning.

This model is especially relevant in installations that already use the IP-12SYSM and need additional passive speakers. Because both models share the same industrial design, active and passive speakers can be combined while maintaining a visually seamless appearance across the installation.

Why Choose This Model

The IP-12SYSP combines a defined suspended-ceiling form factor with specifications focused on announcements and background music. Its 110Hz to 6kHz frequency response establishes the stated operating range, and its wide horizontal and vertical dispersion supports coverage across a large listening area. These specifications make it possible to evaluate the speaker using documented frequency, sensitivity, output, and coverage information instead of relying on an undefined extension-speaker profile.

It is also UL1480 and UL2043 certified. The supplied warranty period is 60 months from the date of purchase, providing a clearly stated coverage term for ownership and project documentation.

Installation and Integration

The enclosure measures 5.01 inches high by 23.69 inches wide by 12.10 inches deep, or 127 by 602 by 307 millimeters. Product weight is 9.25 pounds, or 4.20 kilograms, while the listed shipping weight is 13.4 pounds, or 6.09 kilograms. These measurements allow ceiling-space requirements, handling, and delivery considerations to be reviewed before installation.

Audio connection is provided through 22 GA. DQSK bare-wire leads. The speaker's passive configuration and documented lead type give installers specific information for integrating it into a compatible system. Placement can be planned around the stated 120° horizontal and 130° vertical dispersion, with orientation and speaker spacing determined according to the intended announcement or background music coverage. Its UL1480 and UL2043 certifications should be considered alongside the requirements of the planned installation.

Performance Highlights

The IP-12SYSP has a specified frequency response of 110Hz to 6kHz and a sensitivity rating of 95dB SPL. Maximum SPL at one meter is listed as 105dB SPL calculated; retaining the calculated qualifier is important when comparing this figure with other products. Together, these values define the speaker's documented acoustic performance for announcement and background music applications.

Coverage is specified at 120° horizontally and 130° vertically. This broad dispersion is a notable part of the model's performance profile, particularly when the objective is to extend sound across a large space. The published frequency range also provides a clear boundary for evaluating the speaker without implying response beyond the supplied specification.

What Makes It Different

The defining distinction of the IP-12SYSP is its role as the passive companion to the IP-12SYSM. AtlasIED gives the two models the same industrial design, allowing mixed active and passive systems to remain visually seamless. This relationship is useful when an installation calls for coordinated ceiling speakers but requires a combination of active and passive models.

The 1' x 2' suspended-ceiling format, passive design, wide dispersion, bare-wire leads, and matching appearance form a focused feature set. Rather than introducing a visibly unrelated extension speaker, the IP-12SYSP maintains the established IP-12SYSM design while extending the system's announcement and background music coverage.

Final Assessment

The AtlasIED IP-12SYSP is a purpose-defined passive extension speaker for indoor suspended-ceiling installations. It is best evaluated for projects requiring a 1' x 2' format, 110Hz to 6kHz response, 95dB SPL sensitivity, calculated 105dB maximum SPL, and broad 120° by 130° dispersion. Its strongest system-level advantage is visual compatibility with the IP-12SYSM, supported by UL1480 and UL2043 certification and a 60-month warranty from the date of purchase.
