Hailing from Yamaha's Custom series, this NS-M525 two-way surround speaker puts the perfect finishing touch on your home theater system. The speaker is housed in a relatively compact mitered construction cabinet with a luxurious black wood finish designed to complement a variety of audio components and TVs. More importantly, the speaker meets Yamaha's high standards for natural sound reproduction thanks to its Advanced PMD (Polymer-injected Mica Diaphragm) 4-inch cone woofer and 1.12-inch aluminum dome tweeter, which combine to produce a frequency response of 60 Hz to 50 kHz. The woofer is made of Poly-Menthyl-Penten, a durable material that's 15 percent lighter than most other driver designs. The Advanced PMD cone wall, meanwhile, is thicker than most cones (it checks in at 1 mm) yet weighs the same, giving it greater stiffness. The end result is a faster response time, decreased resonance, a better bass response, and a wider dynamic range. In terms of what that means to your ear, you'll hear richer, more natural-sounding vocals and tighter, cleaner passages that transition beautifully from deep bass frequencies to soaring highs.
The tweeter, meanwhile, features an integrated diaphragm/voice coil called a DC Diaphragm. The DC Diaphragm's extra-powerful neodymium magnet can reproduce frequencies all the way up to 100 kHz, an exceptional number for a tweeter of that size. Also new to the M525's tweeter is a redesigned frame that keeps the high frequencies from degrading due to reflected waves, along with an increased aperture angle on the defuser for a more natural sound transmission.
Additional features that improve the speaker performance include a high-performance crossover network at 3 kHz and a chamfered baffle that reduces sound diffraction. For the best home theater performance, listeners should team a pair of NS-M525 surround speakers with the other speakers in Yamaha's Custom NS-525 series, which includes tonally matched front tower speakers (NS-525F) and a center channel speaker (NS-C525). The speaker is also magnetically shielded against video interference, so you can locate it next to a TV without distorting the picture. And as a final bonus, the NS-M525's extruded, gold-plated five-way binding post terminals ensure the best possible sound.
The Yamaha NS-M525 speaker, which boasts a power rating of 30 watts nominal and 120 watts maximum, measures 6.94 by 12.69 by 7.31 inches (W x H x D) and is backed by a two-year warranty on parts and labor.
