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!

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.

Power Handling Note

Magnetic Shielding: Each speaker is magnetically shielded, so they can be placed near a TV or video monitor without degrading the picture via stray magnetic fields.
Spring-Type Terminals: The spring clips will accept pin connectors and bare wire.
New Grille Design: The new grille design and satin grille cloth provide an attractive and acoustically transparent protective cover for the drivers.
