But unfortunately, as always existing at the primary stage of every industry, there are quite a few of badly-equipped small factories looking after quick money.

DEMA products are mostly exported to European markets, some are well accepted in many Asian countries, and quickly gain the market favor from some American, Australian, African countries. High end acoustic system of DEMA, the sound reversion can reach even surpass some well-known European or American brands.

The task for future is still painstaking and there is a long road to walk. Our mission is to be an Excellent Acoustic Equipment Provide all over the world!
