  • Complete 7-speaker home-theater set for immersive surround sound
  • Center channel uses dual 2.5" woofers for clear dialogue at 90Hz-20kHz
  • Six satellite speakers feature 3" mica woofers and .5" PEI dome tweeters
  • All cabinets sealed with spring-loaded raw-wire terminals for simple amp connection
  • Mounting brackets and hardware included for flexible wall or ceiling placement

Seven-speaker home-theatre set

This seven-piece kit pairs one AA32CB centre channel with six AA351B mountable speakers for a complete front, centre and surround layout. All units are passive and draw power from a home audio receiver with raw speaker-wire outputs. The sealed black ABS cabinets keep the footprint compact while delivering full-range coverage. Each speaker includes mounting hardware for quick wall or ceiling placement.

Build integration and wiring needs

The centre channel uses two 2.5" polypropylene woofers rated at 90 Hz–20 kHz and 90 dB at 8 ohms, while each satellite employs a 3" poly-mica woofer and 0.5" PEI dome tweeter rated at 100 Hz–20 kHz and 89 dB at 8 ohms. Your amplifier must supply no less than 20 W and no more than 200 W per channel. Spring-loaded raw-wire terminals accept CL3 or standard speaker cable, so no proprietary connectors are required. The system is not rated for outdoor use.

Upgrade path and when to step up

This set replaces basic sound-bar or two-channel stereo arrangements with discrete centre dialogue and dedicated surround channels for movies and music. The jump is worthwhile when a receiver with at least five powered channels is already available and the listener wants directional effects without running in-wall cable for rear units. Buyers who need powered speakers, wireless rear channels or weather-resistant cabinets should look elsewhere.

Questions about this item

What is the minimum amplifier power per channel needed for this speaker set?

The system requires an amplifier delivering at least 20 watts per channel and no more than 200 watts per channel to drive all seven speakers properly.

How much heat or noise do these passive speakers generate during extended use?

As passive speakers they produce no electrical noise or heat themselves; any warmth comes from the connected amplifier, which should stay within its 20–200 W per channel rating.

What cables and connectors must I already have to install this 7-speaker system?

You need CL3-rated or raw speaker wire for each channel and a receiver with spring-loaded raw-wire outputs; the speakers include mounting brackets and hardware.
