Don't let the compact cabinet or the affordable price tag fool you — the NS-6390 delivers big sound that doesn't skimp on Yamaha's trademark musical precision. It features a 3-way design for impressive power handling, and solid, accurate performance from top to bottom. The NS-6390's video-shielded, acoustic suspension enclosure incorporates a 3/4" fluid-cooled dome tweeter, a 4" midrange, and an 8" woofer. You'll love the clean, punchy sound! Both the midrange and bass drivers feature inverted dust covers for added durability.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

New Grille Design: The new grille design and satin grille cloth provide an attractive and acoustically transparent protective cover for the drivers.
