Samsung HW-J4000 Wireless Curved Soundbar – Complete Review

Flat-screen TVs are getting slimmer and slimmer by the day. While this is good news as it signals technological advancement, it has one downside – weak speakers with tinny sound. The slimmer your TV’s display screen, the weaker its built-in speakers. To overcome this problem, TV companies introduced soundbars, a revolutionary sound device that took care of your TV’s feeble sound and transformed it into robust ground-shaking audio.

A soundbar is essentially a collection of drivers consisting of tweeters, midrange and woofers housed inside a single cabinet. Each driver has a special function in that it is intended to process a specific band of frequency. When the audio signal enters the soundbar, it is split up into smaller frequency bands. The higher frequencies are handled by the tweeters, the middle ones by the midrange and the lower frequencies by the woofer. This makes sure every nuance of sound is suitably highlighted so that the overall quality of your TV’s sound improves.
