A sealed box is an airtight enclosed space housing your subwoofer. A sealed box is the most excellent for any music that demands accurate, tight bass. Expect flat response, deep bass extension, and outstanding power handling. Since a sealed enclosure tends to need more power than a ported box, use an amplifier with ample wattage for optimal performance.
Each beat in a tight bass setup plays crisply, precisely, and with no ringing after it hits. The sealed air inside one of these enclosures acts such as a shock absorber, smoothly modulating the subwoofer cone’s back and forth motion, so all the notes get produced consistently.
Importance of 18 inch subwoofer
Without an enclosure, the sound-waves coming from the speaker’s backside cancel-out low frequencies coming from the front, making the sub sound weak or even non-existent. What you may not know is there are two different kinds of bass schools: “tight” and “boomy.” Some people wish for a tight bass sound.
A great 18 inch subwoofer box will reach down to 20Hz or lower, right down to the edge of human hearing. This means you never miss a note and can even feel the lowest notes from something like a kick drum, pipe organ, bass guitar or the occasional cannon volley from the 1812 Overture, for a much more better experience.
How does subwoofer enhance sound quality?
Subwoofers add bass and simplicity to your stereo’s sound. And they can also add to a system’s performance in a range of ways. A quality subwoofer will add profundity and realism to your music that you would otherwise miss out on with a factory car stereo system.
While you may hear the bass from your bookshelf or floor standing speakers, a subwoofer enables you to feel the sound. Listening to bass-heavy music like hip hop or EDM or watching a full-throttle action flick without a subwoofer leaves a lot to be desired.
A subwoofer is a loudspeaker meant to reproduce low-pitched audio frequencies, known as bass and sub-bass that are lower in frequency than those which can be generated by a woofer. You can place the sub about a third of the way from the wall into the room and this will produce the most even bass response. If this is not viable, try a spot that is one-fifth of the way into the room.
