Planetary Gong Plates - Bass Octave

Planetary Gong Oblong Bass is two octaves lower than Gong Oblong Standard Size. Due to physical properties the exactly tuned frequencies are only one octave lower. The plate bell is by far the most powerful of the seven treasures.
The pure, intense sound originates from tuning the plates to two frequencies an exact octave apart.  Manufactured from bronze, hammered, fired and polished (premium) and brass with fine polish (bass).
