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 dual 6-1/2" M.M.D. cone woofers conduct 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 woofers use a rubber surround.

Midranges: The speaker uses a 4" M.M.D. cone midrange with 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.
