Audio-Technica - Powered Bookshelf Speakers - AT-SP3X

A compact powered pair that needs no amplifier or receiver — just a turntable with its own phono stage, or anything with a line output.

The AT-SP3X is a two-way design: each cabinet carries a 76 mm (3 inch) woofer and a 27 mm tweeter, and the left cabinet holds the amplification and drives the right through the supplied cable. Audio-Technica rates the system at 30 watts maximum output with a frequency response of 55 Hz to 20 kHz.

Connection is either a stereo RCA line input or Bluetooth 5.3, and the Bluetooth implementation supports multipoint pairing so two devices can stay connected at once. Cabinets are 7.9 inches tall with a power LED and volume dial on the front.

Worth being clear about the input: it is line level, not phono. A turntable needs a built-in preamp of its own, an external phono stage between the two, or a Bluetooth connection. Audio-Technica's own AT-LP60XBT, AT-LP70XBT and AT-LP120XBT-USB all pair over Bluetooth, and any deck with a switchable phono/line output works over RCA.
