Our take on the AA321B Mountable Bookshelf Speakers

The AA321B is a set of small passive bookshelf speakers with omni-directional mounting brackets, meant to be driven by an amp or receiver. Each cabinet is 3.5 x 3.5 x 4.5 inches with a 2.5-inch polypropylene woofer and a sealed black ABS enclosure rated 8 ohms, 88 dB, 150 Hz to 20 kHz. They suit surround and satellite duty, fill speakers or a small multi-room setup where a full-size speaker won't fit. Against typical satellite speakers they trade deep bass for compact size and flexible mounting; owners treat them as background and effects speakers rather than main stereo pair.

Questions and answers

Do these need an amplifier?
Yes. They are passive speakers with no built-in amp, so they must be wired to an amp or receiver rated for an 8-ohm load.
How much bass do they produce?
Little. The rated response starts at 150 Hz, so a subwoofer or larger mains are needed for low frequencies.
Can I mount them on a wall or ceiling?
Yes. Omni-directional mounting brackets and hardware are included for wall or ceiling placement.
Can they be used outdoors?
No. The maker does not recommend them for outdoor use.
What connections do they use?
Spring-loaded terminals that take raw speaker wire, not RCA or banana-only plugs.
