The C612 delivers way beyond what you'd expect from such an affordable speaker. Its 6½-inch polypropylene woofer puts out deep bass down to 45 Hz, while its 1-inch pivoting soft-dome tweeter sings out with smoother treble than you'd expect from such an affordable speaker. You get true party-level sound without a subwoofer!
With super-high 91 dB sensitivity, the C612 works great with any amplifier. Just 8 watts will get this speaker up to 100 dB! The C612 also has an 8-ohm nominal impedance, so it's an easy load for any amplifier to drive. And for simpler installation, it uses the same mounting template as all of Proficient Audio's 6½-inch ceiling speakers.
