Some user feedback from Sinbosen customers
From professional stage performances and large-scale conference sound reinforcement to outdoor music festivals and home theater setups, Sinbosen’s audio equipment has consistently earned recognition from customers across numerous countries and regions. For over a decade, Sinbosen has prioritized product quality and after-sales service as its core strengths, offering a three-year warranty and 18-hour online technical support. Below, we have compiled genuine feedback from customers across various application scenarios:
Customer 1:
This customer from Mexico purchased the Sinbosen WL12 dual 12-inch line array speaker and reported that the product is of exceptional quality and well-engineered.
The WL12 is a dual 12-inch, three-way line array system featuring a fully horn-loaded design and bi-amplified operation. By applying horn-loading technology across all frequency ranges, the system effectively boosts acoustic output energy in the low, mid, and high frequencies, thereby achieving high sound pressure level (SPL) output.
Client 2:
This feedback comes from a client in Poland who purchased the QT-1 dual 10” line array loudspeakers and the D4-3000 1U digital power amplifier. The client gave the audio system a perfect 5-star rating for sound quality and indicated that they would use it for various events in the future.
Client 3:
This feedback comes from a client in Mozambique who purchased the KA212—a dual 12-inch passive line array speaker—and used it in his performances. Impressed by the speaker's excellent sound quality, he intends to purchase more units.
The KA212 dual 12-inch line array speaker delivers powerful output and high sensitivity, producing clear, rich sound, making it an ideal choice for events in large venues.
Customer 4:
This is feedback from a customer in the United States who purchased Sinbosen DS-10Q and DS-20Q 2U stage amplifiers. He reported that the amplifiers were very well-received and indicated plans to purchase more in the future.
Both the DS-10Q and DS-20Q are 4-channel Class TD switching power amplifiers. They feature efficient heat dissipation, with eight additional fans on the rear panel bringing the total number of built-in fans to twelve, and include built-in thermal, over-current, and short-circuit protection. The DS-10Q is suitable for 15-inch line array speakers, while the DS-20Q is suitable for 18-inch subwoofers.
Customer 5:
This feedback comes from a customer in Mexico who purchased Sinbosen D-series and K-series 1U digital amplifiers. He considers them to be highly reliable, high-performance amplifiers.
Both the Sinbosen K-series and D-series are 1U digital amplifiers that support a wide voltage range of 90V–240V. The key difference between the two series is that the D-series supports 2Ω operation, whereas the K-series does not.
