The S-525 Center Channel is the perfect accompaniment to the S-520 mini-monitors. It shares the same polypropylene woofers, soft dome tweeter and high-quality finish options. Just like its sister speakers, the S-525 is constructed of thick MDF, covered with a solid wood veneer and protected with several layers of clear coat. It is also a perfect match in both tone and timbre. Features include twin-tuned ports, two 5-inch woofers, four solid brass speaker terminals for bi-wiring and bi-amping and standard jumpers.
