Beautiful craftsmanship, loud tone
Bought this for a cultural demonstration, but it works perfectly for its intended warning purpose too. The copper finish is stunning. Only giving 4 stars because the stand assembly instructions were slightly vague.

Excellent clarity for emergency use
We purchased the 42cm set for our village flood defense team. The sound carries incredibly well over the river noise, ensuring everyone hears the warning immediately. The build quality is solid.

Great value for a complete set
Getting the gong, drum, and cymbals together saved us money. The cymbals are particularly sharp and cut through wind noise effectively. Shipping took a bit longer than expected.

Superior to electronic sirens
In areas where power might fail during a storm, this mechanical set is invaluable. The 32cm size provides the perfect balance between portability and volume. Highly recommended.

Reliable in all weather conditions
Has been mounted outside for six months through rain and sun. The plating holds up well, and the sound has not degraded. Essential equipment for our coastal monitoring station.

Authentic and powerful
The resonance of the pure copper is unmatched. We use this for both ceremonial purposes and as a backup alert system. It feels like a piece of history that still serves a vital modern function.
Q: What is the effective range of the sound for the 42cm gong?
A: Under normal atmospheric conditions, the 42cm gong can be clearly heard up to 1.5 kilometers away, depending on terrain and wind direction.
Q: Do you offer replacement beaters or mallets?
A: Yes, we sell hardened wood and rubber-tipped mallets separately. Please check the accessories section of our store for compatible sizes.
Q: Can these instruments withstand continuous outdoor exposure?
A: Yes, the Sanjuban sets are treated with a protective finish designed to resist oxidation and weather damage, making them suitable for permanent outdoor installation.
Q: Is the 15cm size loud enough for a small neighborhood alert?
A: The 15cm model is best suited for immediate vicinity alerts or indoor use. For neighborhood-wide warnings, we strongly recommend the 32cm or 42cm models.
Q: How difficult is it to mount the frame on a concrete wall?
A: The kit includes anchor bolts for masonry. While the process is straightforward, we recommend two people for installation due to the weight of the larger units.
