Seven-speaker home-theater set

This Acoustic Audio by Goldwood package supplies seven passive speakers for a centre, front, middle and rear surround layout. The centre channel uses two 3-inch polypropylene woofers and a 1-inch soft-dome tweeter, while the six satellite speakers each use a 2.5-inch polypropylene driver. All cabinets are sealed black ABS with spring-loaded raw-wire terminals.

Passive design requires external amplification

Every speaker is passive, so a home audio receiver with raw speaker-wire outputs is mandatory. The centre channel handles 70 Hz to 20 kHz at 92 dB sensitivity and 8 ohms, while the satellites cover 150 Hz to 20 kHz at 88 dB and 8 ohms. Amplifier power per channel must stay between 20 and 200 watts, and wiring must be CL3-rated or standard raw speaker cable.

Wall mounting with included brackets

Each satellite ships with an omni-directional mounting bracket and hardware for on-wall placement. The centre unit measures 4.125 by 9.625 by 3.875 inches and the satellites 3.5 by 3.5 by 4.5 inches, so verify wall space before drilling. Spring terminals accept bare wire only; banana plugs or spades will not fit. The system is not rated for outdoor use.

Questions about this item

Should I pick the AA35CB centre or the AA321B satellites for my front channels?

The AA35CB is a dedicated centre channel with two 3" woofers and a 1" soft-dome tweeter covering 70Hz–20 kHz at 92dB; the AA321B satellites use a single 2.5" woofer each covering 150Hz–20 kHz at 88dB. Use the AA35CB for dialogue and the six AA321B units for front, surround and rear positions.

What does the 92dB sensitivity of the centre speaker mean when I connect it to my receiver?

At 92dB (1W/1m) the AA35CB centre produces loud, clear dialogue with modest amplifier power; paired with a receiver delivering 20–200W per channel it will reach reference-level film volume without strain.

What does the 8-ohm nominal impedance cap in practice?

Both the AA35CB centre and AA321B satellites present an 8-ohm load, so any home audio receiver with raw speaker-wire outputs rated for 8 ohms and 20–200W per channel will drive the full 7-speaker set safely.
