Infinity's Primus 360 floor-standing speakers (the top-of-the-line Primus towers) deliver dynamic performance for both movies and music. The 3-way design includes dual 6-1/2" woofers, a 3/4" tweeter, and a 4" mid; you'll enjoy clear, rich sound all across the audio spectrum. The drivers are made from Infinity's exclusive Metal Matrix Diaphragm (M.M.D.™) driver material. Derived from the C.M.M.D. material used in Infinity's high-end Prelude™ speakers, M.M.D. sports a stiff aluminum core that helps the drivers turn out crisp, lifelike sound with minimal distortion. They consistently outperform other driver materials on tower speakers in this price range.

Other cool features include 5-way binding posts for sure connections, and solidly built cabinets for reduced internal resonance. The 360s make an excellent pair of stereo speakers — the high sensitivity rating means you can play them loud without straining your amp. They can also anchor an impressive front soundstage in a home theater setup.

Recommended center channel: Primus C25.
Recommended surrounds: Primus 150 or Primus 160.

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.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
