Our take on the Infinity Primus C25

by Tom Mathew

The unsung hero of any home theater speaker system is the center channel. Directional special effects are impressive, but it's the center channel that reproduces the dialogue and anchors the on-screen sound to your television's picture. Infinity's Primus C25 center channel speaker includes a 3/4" tweeter for detailed highs and dual 5-1/4" woofers for solid, realistic mids — essential for reproducing the human voice. All the drivers are made from Infinity's exclusive Metal Matrix Diaphragm (M.M.D.™) material, which outperforms other driver materials in this price range. M.M.D. features a stiff aluminum core that enables the C25 to produce exceptionally clear and accurate sound.

The C25 is voice-matched to all the speakers in the Primus line. Team it up with the Primus 250 or Primus 360 towers for an impressive front soundstage in a large-room home theater setup. Or match it to the Primus 150 or Primus 160 bookshelf models for convincing home theater in smaller rooms.

Features

Metal Matrix Diaphragm (M.M.D.): 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 5-1/4" M.M.D. cone woofers offer extremely accurate midrange response for cleaner, more realistic sound. For a smoother response and improved durability, the woofers use rubber surrounds.

Tweeter: The speaker has a 3/4" M.M.D. dome tweeter that offers superior stiffness and damping compared to traditional metal domes.

5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Crossover: The crossover is a 2-way 4th order (24dB/octave) at 3000Hz.

Matching System: The C25 is voice-matched to all the speakers in the Primus line, so a complete matching system can be built.

If size is not an issue, best band for your buck

Written By Tom, Santa Fe, NM on Friday, March 02, 2007

Well like most past reviewers I figured I would take advantage of it since Infinity is discontinuing the C25 and replacing it with the C25 Beta.

This center is great. I was using an underpowered center with my pair of Primus 360s for a while to try to wait for a sale on the C25 and the difference is obvious. Dialog is much more clear and crisp, which is very important to me.

I hooked mine up with Monster XP cable (same as my Primus towers) and think the performance is great. It may not be the most attractive speaker but it is great with its performance.

For the price you really cannot beat this center channel. The only drawback is the size. I had to relocate some other components to make room for this beast, which wasn't a big issue. It looks great paired with some Primus towers.
