About the Classia C336

The Infinity Classia C336 is a 3-way passive floorstanding loudspeaker using CMMD (Ceramic Metal Matrix Diaphragm) drivers in a bass-reflex, rear-ported enclosure. It employs three 6-1/2 inch (165mm) CMMD woofers, a 4 inch (100mm) CMMD midrange, and a 1 inch (25mm) CMMD tweeter, all magnetically shielded for flexible placement near video displays. The system offers a frequency response of 40Hz-30kHz (-3dB), extending to 35Hz-40kHz (-6dB), with a sensitivity of 91dB (2.83V/1m) and a nominal impedance of 8 ohms. Recommended amplifier power is 10-250 watts, and the crossover network uses 24dB/octave slopes at 500Hz and 2.8kHz. The cabinet stands about 48-3/4 inches (1238mm) high, 8-1/2 inches (216mm) wide, and 10-1/2 inches (267mm) deep, with a weight of 56.1 lb (25.4kg). The angular MDF enclosure with curved laminated side panels was offered in cherry wood veneer or high-gloss black. Connection is via heavy-duty, gold-plated binding posts, and the C336 supports bi-wiring/bi-amping configurations. Reviewers note strong bass extension and a wide soundstage, with some criticism of limited bass punch and a slightly fatiguing treble in some setups.
