Do you think you need a subwoofer?


Why almost any one needs subwoofers in their audio systems?

I talk with my audio friends about and each one give me different answers, from: I don't need it, to : I love that.

Some of you use subwoofers and many do in the speakers forum and everywhere.

The question is: why we need subwoofers ? or don't?

My experience tell me that this subwoofers subject is a critical point in the music/sound reproduction in home audio systems.

What do you think?

Experiment. The bass may appear fragmented or incomplete but it works its auditory illusory magic with considerable authority. Put on a piece that has critcal bass, e.g. Yo Yo Ma Bach Sonatas. Ensure the bass and upper frequencies are balanced. Then measure the sound levels three ways: combined, bass only and without bass. You'll be surprised how high the dbs are for bass only. I use a separate modded BK 442 (200wpc) amp to drive a pair of separate passive sealed 10inch Hales bass drivers through an active crossover so its always adjustable. I turn the bass way down on poor bass recordings where the woofer just pumps, e.g. sadly RCA LP Heifetz/Reiner Tchaikovsky Violin Concerto; I couldn't do that with an internal three way fixed crossover. A modded BK M200 monoblock (200wpc) amps drive the mid/tweeters. I'm always surprised how much presence the bass driver creates and how hard the bass amp works. Through countless trials I now set the crossover at 120hz. A cello works the bass amp harder than the mid/tweeter amp. I can feel the difference in the heat sinks.
