Overview
Feedback
Acesonic has designed their own speakers for the best audio
performance! The Acesonic SP-450 is a bass reflex professional karaoke speaker
that dishes out surprisingly rich, full sound. It takes advantage of the latest
technology geared towards singers ?the 10" woofer and two 3" tweeters provide
smoother response and better detail than other speakers of the past. And these
speakers don't just sound great; with it's three dimensional curved design, they
look great, too!
What is a bass reflex
speaker? Unlike an
acoustic suspension speaker that uses a sealed enclosure, a bass reflex
speaker includes 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, efficiency is
better - a bass reflex speaker will play louder than an acoustic
suspension speaker when driven with the same amount of amplifier power.
This can be a big benefit, especially if you're using a low-powered
receiver or amp.
