BASS TONE BARS
Powerful - Powerful bass tones fill the room. Large wide-scale bars and cavity resonators, result in substantially louder tones than thin narrow-scaled bars and column resonators used in commercially-designed standard and bass marimbas.
Deep - Extended low end frequency covers the range from Tenor C (C3) = 130.8Hz down to Contra Bass C (C1) = 32.7Hz.
Note: If interested in pitches below these ranges (e.g. Sub-Contra Bass [C0 – 16.35Hz]), please contact Chris to discuss.
Accurate - Pitches are tuned to the A-440 (Hz) pitch standard and are accurate to within +2 / -0 cents at 70-degrees F. True strobe tuners (having mechanical rotating-discs) are used, along with a CCBANTA specifically-designed test equipment and testing procedure, to measure the tuning accuracy of the bar, the resonator, and the coupling of both components for maximum resonance.
Durable - Robust bars are made of hard maple and protected with a multi-coat water base finish, which makes them practically indestructible from heavy-handed playing. Bars are suspended with a heavy duty cord and spring tensioning system. Resonators are made of ¾-inch void-free Baltic Birch plywood and are structurally braced so there are no functional losses while being played.
Amplifiable - In addition to the acoustic resonance of the pitch, each bar contains a piezo-electric transducer and 1/4-inch jack. This allows for each tone bar to be plugged into a mixer/amplifier system so the bar's vibration can be amplified electronically. To feel the full power of these low pitches, sound reinforcement systems containing sub-woofers are recommended.
