Indoor bookshelf speaker pair

The Acoustic Audio AA40CB is a two-piece passive bookshelf set designed for indoor listening rooms, home-theatre surrounds or whole-house audio installations. Each cabinet houses two 4" polypropylene woofers and a 1" soft-dome tweeter in a sealed black ABS enclosure. Spring-loaded raw-wire terminals accept CL3 or bare speaker cable from any compatible amplifier or receiver. The pair ships with an instruction manual and carries a lifetime warranty against manufacturer defects.

20–250 W per channel amplifier requirement

The single specification that decides compatibility is the amplifier power window: your amp or receiver must deliver no less than 20 W and no more than 250 W per channel into 8 Ω. Falling below 20 W risks clipping and distortion, while exceeding 250 W can overdrive the drivers and void the lifetime warranty. Match your electronics to this range before purchasing.

Sustained output within 94 Hz–20 kHz bandwidth

Under continuous programme material the speakers maintain their rated 94 dB sensitivity across a 94 Hz to 20 kHz frequency response. The sealed cabinet alignment prevents port chuffing during extended low-frequency passages, and the polypropylene cones resist thermal compression during long listening sessions. They are not rated for outdoor exposure, so environmental moisture will degrade sustained performance over time.

Questions about this item

What does the 1000W rating mean when I connect these speakers to my amplifier?

The 1000W figure is a peak system rating for the pair; each speaker handles 20 to 250W continuously, so match your amp's per-channel output to that range.

What connection standard do the spring-loaded terminals use and what wire gauge do they accept?

The terminals accept raw speaker wire or CL3-rated cable; they clamp bare wire ends directly with no banana-plug or spade requirement.

How much shelf depth do I need for each 5.75 x 15.625 x 5.75 inch cabinet?

Each bookshelf speaker is 5.75 inches deep, so allow at least that much clearance plus a little extra for the rear-facing wire connectors.
