Mackie C300z Compact Passive, Unpowered 2-Way Loudspeaker (1x12")

A passive version of the SRM450, the Mackie C300z features the same lightweight cabinet and excellent sound. Handles 600 watts peak power with a 12" woofer. Unpowered. Requires separate power amplifier.

Mackie's C300z 2-Way Portable Passive Loudspeakers put the superior clarity, wide dispersion, and legendary ergonomics of the SRM Series within reach of any serious musician, DJ, or small club. These compact-yet-loud speakers can be pole-mounted for use as a small full-range PA system, combined with subwoofers as needed, and even employed as high-quality passive floor monitors.

Precision Tuned by the Speaker Brains at EAW

The C300z passive loudspeaker represents Mackie's first lightweight passive speaker tuned exclusively by the EAW loudspeaker engineering team. This is the same team with more than 25 years of high-output loudspeaker expertise, having created loudspeaker systems for critical applications as diverse as the Super Bowl, Iron Maiden, and the Pope. And although loudspeakers for these mega-systems cost exponentially more than the stalwart C300z, many of the same concepts applied, namely: designing custom 12" LF drivers with a frequency range from 50 Hz - 3000 Hz and a 3" voice coil that can take a pounding. And a 1.75" High-Frequency titanium Driver and Horn providing a wide, controlled dispersion pattern and precise reproduction of the critical 1000 Hz - 20,000 Hz upper mid-range and high frequencies.

Crossovers Tuned to Perfection

Tuning a crossover (i.e. voicing a system), involves dozens of critical decisions that many manufacturers overlook. In the end, it is all about balancing the design so that you get the best subjective read more results from the speaker while maintaining a good technical implementation. The crossover in the Mackie C300z is a unique Low Impedance Compensated Crossover (LICC) design with an asymmetrical slope. With EQ and crossover points meticulously chosen so that beamwidth patterns match in both drivers, C300z loudspeakers offers natural sound at all volume levels.

Ultra-Wide Dispersion

Ever been to a show where the music sounds great in front, but craps out once you get to the back or sides of the room? Everyone has, and that's why Mackie gave the C300z a multi-cell horn throat aperture. Sure, it's hard to say, but what it does is allow for much wider and more even dispersion of high and mid frequencies-so the wallflowers get the same great listening experience as those up front.

Better Than Your Average Box

Anyone with a factory can build a box and stick some speakers in it (and that's just what many do). But low-frequency transducers in square boxes can create resonances that reflect off the rear wall and pass through the woofer cone out of phase and ready to mess up your sound. The Mackie C300z enclosure is an asymmetrical monocoque design with no parallel surfaces, causing mid and high frequency resonances to be reflected at angles into internal damping materials, instead of interfering with the woofer doing its thing.

Makes a Superb Floor Monitor

A good floor monitor plays loudly without generating feedback through vocal microphones. A poor floor monitor, on the other hand, will generate feedback just about the time you turn it up to a useable level. Floor monitor feedback is often caused by uneven frequency response and dispersion; some frequencies arrive at the microphone much louder than others. These "spikes" are what trigger feedback as the floor monitor volume is increased. The Makie C300z has incredibly smooth, spike-free response and dispersion over a wide range of treble frequencies. So you can increase its volume without boosting those nasty, feedback-inducing spikes. Without extensive tuning, no passive speaker or specialized floor wedge in this class can even come close.

Note: Unpowered speaker, requires separate power amplifier.

I purchased the mackie 10 inch C200 speaker for small gigs with my band. I was so impressed with the dispersion and sound quality that we purchased a set of the mackie 12 inch C300 for the med sized gigs and used the c200's as monitors. The C300's really worked well at a outside gig we played recently. I highly recommend them for any working musician.
