Features

Overview: The Infinity Primus Theater Pack consists of four identical 2-way satellite speakers with a 4" woofer and 3/4" tweeter, plus a center speaker with dual 4" woofers and a 3/4" tweeter. You can add an optional Infinity PS-series subwoofer (see items 108PS8, 108PS10 or 108PS12) for a complete 5.1-channel home theater speaker system. To complete a 6.1- or 7.1-channel surround speaker system, you can add one or two additional matching satellite speakers (item 108P140).

Metal Matrix Diaphragm (M.M.D.): All of the speakers in the Primus Series feature Infinity's proprietary Metal Matrix Diaphragm (M.M.D.) drivers. Derived from the C.M.M.D. material used in Infinity's flagship Prelude drivers, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels.

Woofers: The 4" M.M.D. cone woofer conducts sound faster than paper, polypropylene and Kevlar found in many similarly-priced speakers, pushing unwanted resonances beyond the operating range of the transducer. For a smoother response and improved durability, the woofer uses a rubber surround.

Tweeters: The speaker utilizes a 3/4" M.M.D. dome tweeter and waveguide to deliver a wider, more even, high-frequency response.

Enclosures: The satellite speakers are housed in bass reflex enclosures with front-firing ports. The center channel speaker is an acoustic suspension enclosure.

5-Way Binding Posts: The gold-plated 5-way binding posts will accept pin connectors, spade connectors, banana plugs, dual banana plugs and bare wire. Note: Plastic inserts must first be removed from the speaker terminals before connecting banana plugs or dual banana plugs.

Wall Mounting: The Primus satellite speakers are designed to mount directly to a wall via the two keyholes on the back. Two rubber "bumpers" at the bottom of the back panel provide a non-scratch surface for walls as well as absorb vibrations from the speaker. In addition, there is a 1/4"-20 threaded insert (covered by a rubber plug) located on the back panel for use with third-party speaker brackets/stands. Note: The satellite speakers weigh 7 pounds each, therefore proper mounting of the speaker using weight-appropriate brackets and hardware mounted to wall studs is required.
