Features & Design
The C336 is a three-way floorstanding tower speaker with three 6 ½" woofers, a 4" midrange and 1" tweeter, all magnetically shielded. The Classia Series use Infinity's patented CMMD drivers, with diaphragms made of a ceramic and metal compound designed for greater rigidity and higher cone damping. The C336 is a vented enclosure with a rear-facing port. They are relatively efficient with a sensitivity spec of 91dB, so a moderately powered receiver or amp with 75 watts per channel or more will be enough power for them.
The Infinity towers can also be bi-wired or bi-amped for better performance.
The striking visual appearance of the Classia 336 speakers makes them well suited for a contemporary room décor. They are available in black gloss or Cherry wood veneer with silver accent trim. The unique enclosure design features an angled top that gives them a very avant-garde appearance.
Their height, which is taller than many towers, also makes them a good choice for use next to a rear projection television.
As stereo speakers, they have a neutral sound quality, particularly in the bass, mid-bass region. Bass quantity is dependent on speaker placement as a result of the rear facing ports. Placement close to a wall will produce more bass, so fine-tuning the location is important to achieve the right bass balance.
The bass in Steely Dan's “Aja,” on my seldom-played Original Master Recording LP sounded solid and tight with quick transient response. Vocals imaged well with good center positioning.
Midrange and highs had plenty of detail and sounded well balanced with the bass. Mids and highs sounded very clear and detailed in Diana Krall's “How Insensitive” with excellent center imaging and a wide soundstage. I noted the same soundstage in my review of the Infinity C205 speakers.
Perhaps the best demonstration of the speaker's capabilities was Linda Ronstadt's "What's New" with the Nelson Riddle Orchestra on LP. The imaging from the Infinity speakers sounded extraordinary. Her voice seemed to float between the speakers with a broad and deep soundstage.
I've been watching all six seasons of the hit Fox series “24” in 5.1-channel Dolby Digital. The challenges faced by the main character, Jack Bauer are made even more suspenseful and real by the Infinity speakers. Strong bass, clear dialog and an enveloping sound field created by the Infinity speakers draw the viewer into the story.
