Blaupunkt BS40OK 2-Way Passive Bookshelf Speakers, 40W RMS, 4 Ohm, Brown (Pair)

The Blaupunkt BS40OK is a pair of passive bookshelf speakers that deliver clear, balanced stereo sound with a 2-way bass reflex design. With 40W RMS power per speaker and a 4-ohm impedance, these speakers are ideal for compact hi-fi setups, home theaters, or desktop audio systems where space is limited but sound quality matters.

Advantages

The BS40OK combines a 4-inch woofer for punchy bass and a 1-inch dome tweeter for crisp highs, ensuring a wide frequency response from 60 Hz to 20 kHz. The bass reflex enclosure enhances low-end output without distortion, while the removable fabric grille allows you to customize the look. Screw terminals provide a secure connection for speaker wire, and the MDF cabinet minimizes resonance for cleaner audio.
