14 Speakers for Whole-House Audio

The Acoustic Audio AA321B set supplies fourteen passive on-wall speakers designed for multi-room installations, home-theatre surround systems or commercial background music. Each cabinet houses a 2.5" polypropylene woofer and presents an 8 Ω load with 88 dB sensitivity. The sealed ABS enclosures measure 3.5" x 3.5" x 4.5" and are finished in black. They are rated for indoor use only.

Omni-Directional Brackets Simplify Placement

Included mounting brackets with hardware allow each speaker to be aimed for even coverage across seating areas or retail zones. Spring-loaded raw-wire terminals accept bare conductor or CL3 cable without soldering. The package also contains an instruction manual. No amplifier, receiver or speaker wire is supplied, so those must be sourced separately.

Straightforward Wired Install With Power Limits

Installation consists of securing brackets, running CL3 or raw speaker wire from the amplifier to each terminal, and tightening the spring clips. The amplifier must deliver between 20 W and 200 W per channel; exceeding or falling below this range can damage the drivers or produce weak output. Ensure polarity is consistent across all fourteen units to maintain phase coherence.

Questions about this item

Do the spring-loaded wire terminals need periodic tightening?

The terminals use a spring-loaded design that holds bare wire without screws, so no tightening is required.

What limits how loud these 150 Hz – 20 kHz speakers can play continuously?

The amplifier must supply 20 – 200 watts per channel; exceeding that range risks thermal compression or driver damage.

How warm do the sealed ABS cabinets get during all-day use?

The sealed cabinets dissipate heat passively; with 88 dB sensitivity they run warm but not hot at typical listening levels.
