Infinity Primus PR5012IS 5-1/4 2-Way Speakers (4 Pairs)

The Infinity Primus PR5012IS combines patented Plus One polypropylene woofers, edge-driven tweeters and True 4 ohm architecture for reliable, high-quality sound. Its Plus One polypropylene cones offer up to 35% more radiating cone area than other cones in the same class, resulting in higher sensitivity, increased low-frequency output and a more balanced tonal response. Edge-driven tweeters provide wider dispersion and a smoother high-frequency response while improving power handling for both mid- and high-frequency ranges. The True 4 ohm architecture, featuring low-impedance voice coils, allows amplifiers to reach peak power so you get stronger, clearer sound with improved depth and detail. Infinity subjects these speakers to extreme durability testing—freezing, baking, shaking, ultraviolet exposure and continuous full-power operation for days at a time—to ensure long-term performance. Each speaker is individually voiced rather than produced as an "off-the-shelf" unit: engineers tune using both specifications and measured characteristics to achieve the signature Infinity sound.
