Infinity PR5012IS Primus 5.25 Inch 2-Way Multi-Element Speakers — Two Pairs Included

The Infinity PR5012IS Primus 5.25" 2-way multi-element speakers are built for improved sensitivity, clarity and long-term reliability. Key features include: - Patented Plus One polypropylene woofers: polypropylene cones provide up to 35% more radiating cone area than comparable cones in the same class, yielding higher sensitivity, stronger low-frequency output and more balanced tone. - Edge-driven tweeters: edge-driven tweeters widen dispersion and smooth the high-frequency response while offering increased power handling for both high- and mid-frequencies. - True 4 Ohm architecture: low-impedance voice coils and a true 4 Ohm design give amplifiers room to reach peak power, producing clearer, more powerful sound with improved depth and detail. Durability and tuning: each speaker is individually voiced—Infinity tunes units based on the specifications and acoustic characteristics rather than relying on “off-the-shelf” sound. These speakers also undergo aggressive endurance testing (they are frozen, baked, shaken, exposed to ultraviolet light and run at full power for days) to ensure performance that would fail lesser designs.
