What is the wattage and impedance of the Infinity Primus P163 speaker?

The Infinity Primus P163 has an impedance of 8 ohms, making it highly compatible with almost any standard home theater receiver or stereo amplifier. It has a recommended amplifier power of 10 to 100 watts. This makes it a perfect entry-level audiophile speaker that won't strain budget-friendly AVRs from brands like Yamaha or Denon.

What kind of tweeter and driver design does the Primus P163 use?

The P163 utilizes proprietary Metal Matrix Diaphragm (MMD) drivers, which are designed to reduce resonance and distortion. It is a two-way speaker design, not three-way, featuring a 3.5-inch midrange/woofer alongside a 1/2-inch MMD tweeter. This technology provides incredibly crisp highs and clear dialogue for its price bracket.

Can I use the Infinity Primus P163 as front or rear surround speakers?

Yes, the P163 is incredibly versatile and functions excellently as either front left/right speakers or rear surround speakers in a home theater setup. Because it is part of the classic Primus series, it timbre-matches perfectly with the Primus PC251 center channel and PS8 subwoofer. Many home theater enthusiasts buy multiple pairs of P163s to build a cohesive 5.1 system.

Do the Infinity Primus P163 speakers require a separate subwoofer?

Because the P163 is a bookshelf speaker with a relatively small 3.5-inch woofer, it struggles to reproduce frequencies below 70Hz. If you listen to bass-heavy music or watch action movies with explosive sound effects, adding a dedicated subwoofer is highly recommended. Without a sub, the sound will be very crisp but physically lack deep, rumbling bass.
