Five-Speaker Home-Theatre Set

This five-piece passive speaker package from Acoustic Audio by Goldwood combines a dedicated centre channel with four surround units for a wired home-theatre layout. The centre speaker uses a two-way design with two 3" polypropylene woofers and a 1" soft-dome tweeter, while each surround unit employs a 2.5" full-range woofer. All cabinets are sealed black ABS enclosures with spring-loaded raw-wire terminals.

Sustained Output Behaviour

The centre channel delivers a frequency response of 70Hz-20 kHz at 92dB sensitivity and 8 ohms, while the surrounds cover 150Hz-20 kHz at 88dB sensitivity and 8 ohms. Both models are rated for continuous amplifier power between 20 and 200 watts per channel, allowing extended listening sessions without thermal compression when driven by a compatible receiver. The sealed enclosures maintain consistent bass alignment at typical living-room volumes.

Installation And Common Issues

Each surround speaker includes an omni-directional mounting bracket with hardware for on-wall placement, and the centre unit sits on a shelf or stand. Connection requires CL3-rated or raw speaker wire run from receiver binding posts to the spring terminals. The system is not rated for outdoor use, and polarity must be observed at every terminal to avoid phase cancellation. No active electronics or wireless pairing are involved.

Questions about this item

How much heat or fan noise do the AA35CB and AA321B speakers add when running all day?

The speakers are fully passive with no built-in amplifiers or fans, so they generate no electrical heat and produce zero mechanical noise during continuous operation.

What existing equipment is required to drive the five passive speakers in this set?

You need a home audio receiver with raw speaker-wire outputs capable of delivering 20 to 200 watts per channel at 8 ohms, plus CL3 or standard speaker wire for the connections.

Will the AA321B surrounds blend with my older front speakers that reach down to 150 Hz?

Yes, the AA321B surrounds cover 150 Hz to 20 kHz, matching the low-end limit of front speakers rated to 150 Hz, while the AA35CB center extends lower to 70 Hz for dialogue clarity.
