"Solid bass is the foundation of a good soundstage." That's just a figure of speech, right? Wrong. If the bass frequencies in your system are solid and well-defined, what you'll notice in the music even more than the extra bass, is that the midrange has greater clarity and focus. The highs seem to have greater air and shimmer. Vocals have more realism. In short... everything becomes more musical. Even if you have large speakers with specs that claim deep bass... you'll be amazed at what a subwoofer can do for you!
Why does this happen?
Quite literally... bass is the stage on which all the other frequencies "dance." Think about it... it's pretty tough to dance on a stage that flexes and moves with each step, right? If the stage is solid and strong, it's easier to dance more fluidly, right? Audio frequencies act very much in a similar fashion. The midrange and high frequencies will "dance" on top of the bass frequencies. If those bass frequencies are not reproduced in a solid way, it causes the other frequencies to lose focus as well. Unfortunately, the vast majority of full-range loudspeakers are incapable of reproducing solid, articulate bass down to the lowest frequencies that may exist on your recordings.
That's where JL Audio subwoofers come in.
JL Audio subwoofers have this incredible way of delivering deep, dynamic bass, without over-powering the rest of your system. Plus... they've got a subwoofer for virtually any room size or application: If you're just looking for a single-driver sub for use in a smaller room, we have the Fathom 110. For those of you looking to "go for the gusto," there's the indominable Gotham subwoofer with it's massive pair of 13" drivers. JL Audio offers other models at all points in-between as well... so we can find a subwoofer that fits your needs.
But Uncle Kevin... I hate boomy bass!
I get this comment a lot when the topic of adding a subwoofer comes up. I think that car stereos have given subwoofers a bad rep. In many "tricked out" car stereos (you know... the guy sitting next to you at the stoplight blasting Jay-Z), the subwoofer is used to exaggerate the bass. This is not what we're after in home audio. In home audio... if your subwoofer is properly-calibrated, you shouldn't even notice you HAVE a subwoofer... until you turn it off. The purpose of a subwoofer is to supplement the bass that already exists in your system... not to increase the decibel level of the bass to the point that it's over-run the rest of the music!
Let's look at an example. Say you have a speaker with a low frequency range of 30Hz... pretty low, right? The problem is... when most speakers claim a frequency repsonse of 30Hz... that's well after the decibel level has begun rolling off... so that 30Hz frequency will be a few dB lower than the other frequencies.
In order to maintain a flat frequency response all the way down to 20Hz (the lower limit of human hearing), we need something that is first and foremost capable of producing that frequency, and secondly can be crossed over so that the subwoofer stops at the same frequency where your main speaker begins to pick up... thus creating a frequency response decibel level that is relatively constant.
