Spruce up your stereo or home theater on a dime with Sony's elegant, ash-wood-finished SS-MF650H floorstanding speakers. Designed for hi-fi or, using 2 pairs, full-resolution surround sound music listening, these 3-way/4-driver speakers each employ one 3.25-inch midrange and two 6.5-inch Kevlar/HOP bass drivers, as well as a 1-inch Nano-Fine balanced-dome tweeter. Nano-Fine tweeters extend the speakers' frequency response well beyond the 20 kHz limit of CD audio, all the way out to 50 kHz--perfect for today's high-resolution music formats like Super Audio CD (SACD) and DVD-Audio. The Nano-Fine design makes each tweeter extremely still and light--ideal properties for a tweeter.

The SS-MF650H's ported (bass-reflex) cabinets permit the larger drivers to move more air, significantly enhancing the speakers' low-end output. The speakers use precision crossover assemblies to ensure blending while recreating a seamless sound stage. Today's high-resolution stereo and discrete surround formats can reproduce the same sound out of all speakers. If a variance in drivers, crossover, or materials occurs, the pitch and surround illusion can suffer. Sony speakers are designed using matching driver compliments and crossovers to ensure blending from left to right and from front to rear.

The Kevlar fiber cone material offers an ideal mix of strength and low weight. Traditional driver materials must increase mass to provide greater amounts of rigidity, but these materials tend to be slow and inaccurate. Kevlar, combined with Sony's HOP (Highly Oriented Polyolefin), delivers extremely high strength and low mass. This allows for high power handling (up to 180 watts per channel) and ideal frequency response. HOP is a proprietary speaker-cone material offering high strength, low weight, and low resonance, contributing to the speaker's excellent transient response, high power handling, and flat frequency response. Frequency response extends down to 40 Hz, giving you all but the lowest audible octave of bass.

The balanced-dome tweeter represents a Sony refinement of the classic dome tweeter, which places the voice coil inside the tweeter's circumference for superb dispersion and reduced distortion than traditional tweeters.

The SS-MF650H pair comes with 2 lengths (8.2 feet each) of speaker cable to simplify hookup with your integrated amplifier or surround receiver.
