Five-Speaker Home Theatre Set

This five-piece set combines a dedicated centre channel with four compact satellites for a wired surround-sound layout. It is intended for listeners who want a traditional passive system driven by an existing home audio receiver. The speakers are designed for indoor wall mounting and are not rated for outdoor use. Buyers who need powered speakers or wireless connectivity will need a different solution.

Passive Design and Amplifier Limits

Each speaker presents an 8-ohm load and connects via spring-loaded raw-wire terminals using CL3 or standard speaker cable. The amplifier must supply between 20 and 200 watts per channel; lower or higher output risks damage or poor performance. The centre channel covers 94 Hz to 20 kHz at 94 dB sensitivity, while each satellite covers 150 Hz to 20 kHz at 88 dB sensitivity. No built-in amplification or signal processing is included.

Wall Mounting and Wiring

Four omni-directional bracket sets and mounting hardware are supplied for straightforward on-wall placement. The centre unit measures 5.75 by 15.625 by 5.75 inches; each satellite measures 3.5 by 3.5 by 4.5 inches. Spring terminals accept bare wire but not banana plugs, so strip length must be consistent. The sealed ABS cabinets are not weather-sealed, so avoid damp locations.

Questions about this item

Which speaker model handles the center channel and which handle the front and rear channels?

The AA40CB is the center channel speaker with two 4" woofers and a 1" tweeter, while the four AA321B speakers serve as front and rear left/right channels with 2.5" woofers.

What does the 94 dB sensitivity rating on the center speaker mean for my amplifier?

At 94 dB sensitivity and 8 ohms, the AA40CB produces loud output with modest power, so your receiver only needs to deliver 20–200 watts per channel to drive it cleanly.

What type of speaker wire connection do these passive speakers use and what gauge is recommended?

All five speakers use spring-loaded raw wire connectors and require CL3-rated or standard raw speaker wire to connect to your amplifier's speaker outputs.
