Graphite woofers make the IW630 a truly great-sounding speaker. We designed it to deliver excellent sound quality whether mounted horizontally or vertically. It even fits horizontally between 16-inch-on-center studs, so it doesn't require complicated installation. Serious home theater fans looking for maximum bang for the buck will love the IW630. There's something special about graphite woofers. Yes, they're ultra-stiff for low distortion and maximum power handling, but they also just sound great. Dual 6 1/2-inch graphite woofers give the IW630 incredible dynamics, while the soft-dome tweeter sings out with sweet, smooth treble. Placing the tweeter at an angle to the woofers gives the IW630 great sound whether oriented horizontally or vertically. You can flip the IW630 any which way you want and it'll still fit between standard 16-inch-on-center studs. The pivoting tweeter lets you aim the sound where you need it, and ±3 dB bass and treble switches fine-tune the sound. High 90 dB sensitivity assures the IW630 will get great sound even from an inexpensive receiver. Includes Thin-Bezel Grilles held by Neo Magnets.
