Block SL-250 – Floorstanding Speakers for Powerful, Precise Sound
The Block SL-250 transforms your living room into a concert hall. Building on the compact S-250 bookshelf speakers, these floorstanding speakers significantly enhance the bass foundation and effortlessly fill larger rooms – without sacrificing fidelity. Choose between elegant black or timeless white and pair the SL-250 with any high-quality amplifier of your choice.

Deep bass, crystal-clear mids and highs
The 6.5-inch mid-woofer with an extremely rigid Kevlar diaphragm delivers a tight, controlled bass foundation down to 30 Hz – perfect for movie effects and dynamic musical passages. From 3.5 kHz, a finely detailed soft-dome tweeter takes over, reproducing voices and instruments with clarity and precision. The rear bass reflex port supports the low-frequency range without creating booming when the speaker is placed close to a wall. With a sensitivity of 88 dB, the SL-250 plays controlled and level even with mid-range amplifiers.
Thoughtfully designed cabinet & flexible placement
The low-resonance MDF cabinet is coated with a satin-matte textured lacquer that is resistant to fingerprints and scratches. The slim 20 cm width allows for discreet integration into living spaces, while the one-meter height provides ideal sound dispersion at seating position. Gold-plated screw/plug terminals guarantee secure contact with stranded or banana plugs. Thanks to the 4-ohm impedance and clean phase response, the SL-250 harmonizes not only with the Block 250 series, but also with amplifiers from other manufacturers – a sonically impressive addition to any hi-fi system.
