Supertek® Four Tone Resonance Box

Take the classic resonance box to a whole new level.

• Four tuning forks with threaded shanks mounted on a single box
• Frequencies of C1 (256), E (320), G (384) and C2 (512) Hz
• Includes activation hammer

Wow students with this fresh take on a classic resonance box. Demonstrate more than just sympathetic resonance between two boxes with forks of the same frequency. This single box demonstrates harmonic overtones, leading to a discussion of wavelengths and nodes.
