The Infinity Reference comes with 6”x9” 3-way car speakers. These speakers fall into the 3-way speaker category. The woofers are constructed out of Polypropylene. The speakers are light, but stiff Polypropylene woofer cones won't flex or distort. Also featured in these speakers are a Plus One+ woofer cone design. The Plus One+ design offers a larger surface area. Plus One+ Woofer Cones provide a significant improvement to overall quality performance. Oversized Plus One+ woofers yield an enhanced midrange sound as well as a wider area for peak bass output. The woofer cones also feature a Hi-roll rubber surround in the unique basket design. Hi-roll rubber surrounds allow a greater range of movement for the speakers. These speakers also include 0.75" Super Tweeters. Similar to many Infinity home speakers, Infinity uses the same Metal Matrix Diaphragm tweeter. This will provide minimal coloration or distortion. The dome tweeters also allow for better stereo imaging by providing pivoting capabilities. With the ability to pivot the tweeters, a more focused sound will heard. The speakers are capable of handling up to 300 Watts Peak Power and 2-100 Watts RMS. Also, possessing a response frequency of 46 - 30000 Hz, these speakers will deliver a quality performance. The impedance registers 2 Ohms while the Sensitivity pushes 94 dB. The speakers have a top-mount depth of 3”.

These speakers have nice clarity and some decent mid bass when needed. They are a great speaker for the price, and an excellent upgrade over factory speakers.
