WHAT YOU HAVE WHEN YOU'RE DONE
These loudspeaker systems could easily be used behind a perforated movie
screen, providing sound to an audience of hundreds of people in a small
movie theater (the original design intent). They are also equally
capable in a home listening room setting, of causing you permanent
hearing loss, and doing so quickly.
I have two tips for you and I urge you to pay heed:
First, play music at no more than realistic levels. I
assume that if you choose to build these things, you've done so because
you're interested in fidelity of the reproduced sound to the originally
recorded sound. You will get the best representation of the original
sound if you play the reproduction at the original sound level. Playing
too loud is as detrimental to fidelity as playing too softly.
If you play predominantly rock music, there is no
such thing as an original sound level-since all the recorded material
comes out of a little electronic box or was derived by sticking a
microphone somewhere you would never purposely put your ears.
In either case, you need to keep a sound level meter
handy. You can get a perfectly adequate SLM at your local Radio Shack
store for around fifty bucks, and for your ears sake, don't ignore this
These speakers make so little distortion that you
will be tempted to believe that the 120 dB sound you are listening to is
only playing at 90 dB. This is not good. You will lose your hearing.
Don't let this happen.
Otologists and other
hearing Experts all warn that persistent ringing in your ears for
several hours after causative auditory events is an absolute
certain indication you have suffered permanent hearing loss!
If you find that the clean sound causes your favorite
rock artist to be emasculated, you can go out and get an Aphex Aural
Exciter to add distortion back in so that it sounds loud again.
