Pioneer S-31-LR-K

The S-31-LR-K is a two-way bookshelf speaker set from Pioneer that is a part of the company's Series 3 product line. Implementing ABD (Acoustic Balance Drive) and AFAST (Acoustical Filter Assisted System Tuning) technologies to maintain a consistent output of low, middle and high frequency signals, this model features a 120-watt power handling and is housed in a Matte Black wood grain enclosure.

Flush-mounted grills help to protect the unit's 4-inch glass fiber cone subwoofer and 1-inch soft dome tweeter, also providing a sleek streamlined effect that makes the S-31-LR-K suitable for any room of the house. Standing wave interference is reduced through the curved design of the unit's cabinet, resulting in high-quality audio output without muddling or distortion.
