Home theater three-speaker set

This set combines an AA40CB centre channel with two AA321B satellite speakers for a compact front-stage array. Passive design means every driver is powered directly by your home audio receiver, so no separate power supplies are needed. The configuration suits buyers building a basic surround system in a small to medium room. It is not for listeners who want floor-standing towers or a dedicated subwoofer channel.

Check receiver power and wiring first

Your amplifier must deliver between 20 and 200 watts per channel into an 8 ohm load to match the speakers’ ratings. You will also need CL3-rated or standard raw speaker wire to run from the receiver to each cabinet. Spring-loaded terminals accept bare wire only, so banana plugs or spades cannot be used. The cabinets are not weather-sealed, so outdoor or damp-room installation is ruled out.

Mounting brackets simplify placement

Two bracket kits with hardware are included, letting you fix each AA321B to a wall or ceiling for omni-directional aiming. The centre channel sits on a shelf or stand thanks to its horizontal 5.75-inch height and 15.625-inch width. All enclosures use black ABS sealed cabinets that keep the footprint small while protecting the drivers. No calibration microphone, remote or processing software is bundled.

Questions about this item

What comes in the box and do I need to buy speaker wire separately?

The box contains three passive speakers — one AA40CB centre channel and two AA321B satellites — plus two sets of mounting brackets with hardware. You must supply your own CL3 or raw speaker wire to connect the spring-loaded terminals to a receiver.

How do the centre channel and satellite speakers differ in driver size and frequency response?

The AA40CB centre uses two 4-inch polypropylene woofers and a 1-inch soft-dome tweeter covering 94 Hz to 20 kHz at 94 dB sensitivity. Each AA321B satellite uses a single 2.5-inch polypropylene woofer covering 150 Hz to 20 kHz at 88 dB sensitivity.

What does the 94 dB sensitivity of the centre speaker mean when driven by my receiver?

At 8 ohms, 94 dB sensitivity means the centre channel produces a strong output level with modest amplifier power, so a receiver delivering 20 to 200 watts per channel will drive it to loud, clean volumes without strain.
