The Pioneer CS-161 is a compact bookshelf speaker that features a 2-way design, providing balanced audio performance suitable for various genres of music and home theater applications. Designed for versatility, it generally employs a 6.5-inch woofer, delivering robust low frequencies, and a 1-inch soft dome tweeter that handles higher frequencies for clear sound reproduction. The cabinet is typically constructed from MDF (medium-density fiberboard) which aids in minimizing unwanted vibrations. With a sensitivity rating around 87 dB and an impedance of 8 ohms, the CS-161 is compatible with a range of amplifiers. The frequency response frequently spans from approximately 45 Hz to 20 kHz, allowing for a deep bass response and crisp treble clarity. These speakers can be stand-mounted or shelf-mounted and are often noted for their pedagogic aesthetics, blending seamlessly into various home environments. The design often features a removable grille and a wood veneer finish, adding to their visual appeal.
