NSY-BS401 Active Bookshelf Pair

The NSY-BS401 is a pair of active 2.0 bookshelf speakers with a built-in amplifier. They connect to a computer, audio interface or turntable through RCA or 3.5 mm inputs, and also support Bluetooth 5.3 for wireless playback.

Upgrade from basic plastic PC speakers

The wooden enclosure reduces cabinet resonance that colours the sound on inexpensive plastic units. Buyers who need more low-frequency extension or a separate subwoofer output will not find those features here.

80 W peak power with 4-inch woofer

The 4-inch driver and 1-inch silk dome tweeter deliver clear highs and tight bass at desktop listening distances. At higher volumes in larger rooms the 80 W peak limit and 4-ohm impedance mean headroom runs out before the system can fill the space.

Questions about this item

How much shelf depth do the NSY-BS401 speakers need?

Each cabinet measures 6.2 in wide, 6.3 in deep and 9.5 in high, so allow at least 6.3 in of shelf depth plus a few centimetres behind for the rear‑facing ports and cable bends.

Which cable do I connect first when setting up the active speaker pair?

Link the two cabinets with the supplied speaker wire before plugging the RCA or 3.5 mm source cable into the master unit, then apply mains power.

When should I replace the 4‑inch woofer surrounds on the NSY-BS401?

Inspect the rubber surrounds every few years; if they show cracking, stiffening or audible distortion at moderate volume, have a technician re‑foam the drivers.
