8-inches, 10-inches, or 12-inches; the active (powered 

speakers): PS-308, PS-310, PS-312; the passive (non-

powered): PS-308A, PS-310A, and PS-312A. The active 

powered Speakers are available for AC power voltage with 

110V and 240V. The KTV/Portable Pro-Line Series portable 

center monitor speakers give you amazing power, size, and 

efficiency for your application. They feature Better Music 

Builder’s latest Coaxial Driver circuitry that delivers crystal 

clear vocal and undistorted sound with the ultimate Home 

Concert Concept for superior karaoke entertainment. 

Professional KTV/Portable Pro-Line Series speakers into the 

home living room. The compact design of the KTV/Portable 

Pro-Line Series can easily be pole mounted or permanent 

installation onto the wall, ceiling, or under balcony. This 

ultra-compact, versatile, and expandable sound quality for 

maximum power and portability in a wide variety of applica-

tions ranging from live musical performance to compact, 

portable performance PA system for classroom instruction, as 

well as preaching and singing in church hall environment.

KTV/Portable Pro-Line Series has elevated the audience’s 

experience by combining the power of professional acoustic 

correction for high definition clarity and performance. While 

the KTV/Portable Pro-Line Series can thrust a huge amount of 

bass with the high performance HF/LF coaxial driver mount 

that audiences can literally feel, and it also comes with the 

premium grade compression driver that is capable of 

delivering the vocal and music in a very precise, focused, 

high-definition quality sound to its very limits, providing 

clearer, and more accurate sound to the entire audience; 

even when used in highly reverberant huge area like 

churches and banquet halls.

engineering team of Better Music Builder, especially for 

public use such as church, school, auditorium and also rental 

for events and social functions.  

The KTV/Portable Pro-Line Series have three different speaker 

sizes of woofer (i.e. 8-inch, 10-inch and 12-inch woofer). 

Speaker of different sizes of woofer has two models: 

active/powdered and passive/non-powdered speakers. 

What makes KTV/Portable Pro-Line Series different from other 

brands of similar product is that KTV/Portable Pro-Line Series 

have the state-of-the-art audio technology using coaxial driver 

to create crystal clear and live sound.
