Frequency Range: depends on surface attached to. Frequencies below @ 100Hz can cause the transducer to jump or rumble.
Impedance: not listed
Power Handling: 6W
Weight: 260 grams (.5 lbs) - it is heavy so it can stand on its own.
Fairly heavy for its size, the weight helps hold it in place. It stands on the round foot (picture is upside-down), which is coated with silicone.
Transmits sound well, though the surface it is one has a huge effect.
This transducer has paired favorably with the Dayton Audio DTA-1 amplifier (15W/channel), and with the Topping TP10-MK4 (15W/channel). Transducer tends to distort when amps are over 3/4 volume.
This transducer stands by itself on the surface, it is fairly heavy, so it does not need attachment unless driven very hard or with low frequencies.
Forms part of Matthew Goodheart's piano transducer set up, in which it is paired with a Clark Synthesis TST239 and both transducers are simply set on the piano soundboard. This set up contains a variable in-patch crossover, which splits the frequency between the two transducers at @ 300Hz. Using this setup, the transducer can be driven at fairly loud volumes without jumping or extra rumbling.
The wires on are fairly thin - a hack to replace the wires with stronger ones is in the works.
This transducer is similar in design to the BCT-2, but has a larger foot.
Sound/stability comparisons have not been done yet.
This transducer is available a Sparkfun and Spikenzie Labs.
