The Acesonic SP-450 Bass-Reflex Professional Speaker System features 2 speaker units designed specifically for singers. It is a bass reflex professional speaker that delivers rich, full sound for the mid-range. It takes advantage of various technologies that is designed for professional and home use.
The 10" (254mm) woofer and two 3" (76.2mm) tweeters provide smoother response and better detail. It comes in a solid black color with an attractive curved design, which makes it suitable for use in any club or home.
Unlike an acoustic suspension speaker that uses a sealed enclosure, these bass reflex speakers feature a port (a hole in the box tuned to a specific frequency) or bass radiator (often referred to as a drone cone) to produce more bass output in a tuned frequency range.
With a bass reflex design, these speakers play louder than an acoustic suspension speaker when driven with the same amount of amplifier power. It is suitable for use in applications where you're using a low-powered receiver or amp.
Attractive 3-dimensional curved design
