Popular karaoke (KTV) club uses JBL KP Series speakers to provide guests with deep, punchy bass and vocal clarity

HEBEI, China— Amid a period of intense economic development in the newly established Xiong’an District of Hebei, China, Good Sound KTV, one the province’s most popular karaoke clubs, is experiencing a boom in business. Described as elegant and luxurious, the club features classical European décor, a full service oxygen bar and a complete HARMAN audio solution implemented by Beijing Zhongzhi Express Electronic Technology, Co., Ltd. Guests can reserve one of 35 rooms at Good Sound KTV and sing karaoke with friends and colleagues in a relaxed atmosphere. 

“The owners wanted each room to have a sound system that could deliver full-range, high-impact sound, without being uncomfortably loud,” said Zhu Yi, Beijing Zhongzhi Express. “Powerful bass, full midrange and smooth treble at high sound pressure levels are necessary for the guests to feel immersed in the song they are singing, but there’s a fine line and crossing it can result in listener fatigue.

and can handle up to 350 watts. Featuring JBL’s patented neodymium compression driver and

woofer, the JBL KP4000 Series and KP2000 speakers provide a wide dynamic range and robust frequency response that is optimized for reproducing the human voice. Bass performance is more than adequate to cover a small room without an external sub. Each set of speakers is powered by Crown amplifiers, known for reliable performance under extreme usage.

“Before we began installation, the owners were concerned that each room would lack a proper bass response without external subs,” said Zhu. “After we demonstrated the impressive range of the JBL KP Series speakers, they were very satisfied


the sound quality. The speaker enclosures are treated with wear-resistant paint and dust-proof grilles, protecting the speakers from spilled drinks and damage from guests. This ensures that they’ll stand the test of time, giving the perfect karaoke experience to guests for years to come.”
