Features

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 5-1/4" M.M.D. cone woofer conducts sound faster than the paper, polypropylene and Kevlar cones 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.

Bass Reflex: There is a single port tube opening on the front of each speaker for increased and extended bass response.

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 150 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. Note: The speaker weighs 13-1/2 pounds, therefore proper mounting of the speaker using weight-appropriate hardware mounted to wall studs is required.
