MoneyMaxx has a set of Infinity tower speakers - Looking for big sound from a pair of tower speakers? The Primus 250 floor-standing speakers take advantage of Infinity's proprietary Metal Matrix Diaphragm (M.M.D.?) driver technology to produce cleaner, more realistic sound even at high volumes. The M.M.D. material features a stiff aluminum core, which greatly reduces cone breakup that causes distortion. The 3/4" tweeter and dual 5-1/4" woofers can easily fill larger rooms with impressive stereo sound. They do a great job with home theater audio, too. With a pair of 250s as your front left and right speakers, movie soundtracks and special effects will play out loud and clear!
