Compact Three-Speaker Set
The Acoustic Audio AA40CB package supplies three passive bookshelf speakers for stereo or surround installations. Each cabinet houses two 4-inch polypropylene woofers and a 1-inch soft-dome tweeter in a two-way layout. The sealed black ABS enclosures measure 5.75 by 15.625 by 5.75 inches and are rated for indoor use only. They present an 8-ohm load with a 94 dB sensitivity figure.
Spring-Loaded Wire Terminals
The speakers terminate in spring-loaded raw-wire connectors that accept bare conductor or pin terminals without tools. No binding posts, banana plugs or proprietary cables are included, so the installer must supply CL3-rated or standard speaker wire. The manual in the box covers basic polarity and placement guidance but provides no calibration software or room-correction features.
Sealed Cabinets and Placement
The sealed ABS cabinets avoid port noise and allow placement against walls or inside furniture without bass boom. Each unit weighs little enough for shelf mounting, yet the 15.625-inch width demands adequate shelf depth. The 94 Hz low-frequency limit means a separate subwoofer is needed for full-range movie effects. Amplifiers must deliver between 20 and 250 watts per channel into 8 ohms.

Questions about this item
How often do the spring-loaded raw wire connectors on these AA40CB speakers need to be checked or tightened?
The spring-loaded raw wire connectors hold bare wire securely; inspect them once a year or after moving the speakers to ensure a firm connection.
What is the first limit reached when these 1500 W speakers run at high volume for long periods?
The 250 W per channel amplifier ceiling is reached before the 94 Hz–20 kHz drivers hit thermal compression.
How much heat do the sealed black ABS cabinets produce during all-day playback?
The passive design generates minimal cabinet warmth; the 94 dB sensitivity keeps amplifier current low, so heat stays negligible.
