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.
The dual 5-1/4" 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.
Tweeters: The speaker utilizes
a 3/4" M.M.D. dome tweeter and waveguide to deliver a wider, more even,
Bass Reflex: There is a
single port tube opening on the front of each speaker
for increased and extended bass response.
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.
