(NEW) The ALTA line is characterized by a thin and tapered cabinet geometry with a high-gloss, lacquered finish. The box design reduces standing waves, leaving the precision crafted woofers to reach their potential and deliver pure, well developed sound. With either the floor standing AL51 tower with four 5.25” woofers, the AL31 bookshelf or the ALC center, a balanced audio tonality is assured. Furthermore, the entire series is magnetically shielded and is equipped with tetetron tweeters and elaborate crossovers. Choosing a stylish ALTA system is easy. Couple an ALC center channel with the AL51 towers, the AL31 satellite models for great sounding stereo and home theatre. *Deluxe high gloss MDF cabinet *Soft dome Teteron tweeter *Magnetically shielded *5 Way gold plated binding post *Thermal protection for tweeter *3 Way BR *4 X 5" Woofer , with rubber surround *1" Teteron Soft Dome Tweeter *Recommended Amplifier Power : 20-150w *Impedance : 6 Ohm *Sensitivity : 89db *Volume : 38.7L *Weight : 60.85 lbs/pr *Dimensions : 40.4" X 7.1" X 8.3" Warranty : 90 days
