The speakers on a stock Windows system do not sound their best. You need to make a small adjustment or two.
First, start playing a rock song (or anything with a good bass track) in the background.
— Open Control Panel, 'Sound'
— Click on 'Speakers', 'Properties'
— Click on the 'Enhancements' tab
— Check the 'Loudness Equalization' box, then 'Apply' down below. It should either stay the same or get a bit louder. This feature plays quieter-than-normal songs slightly louder to compensate.
— If you don't have a subwoofer on your system, you might want to check the 'Bass Boost' box, then 'Apply' and see what you think. It might lower the overall volume a tad but the bass will be louder.
To make sure the overall volume of the system is up, there should be a little speaker icon in the SysTray on the right side of the Task Bar. Click on it and slide the volume all the way up.
With that taken care of, it's time for a system test. Ideally, we want a sound file that will test low frequency response, high frequency response, transient response, tracking and speaker balance.
Thankfully, there's a cut on the 1974 National Lampoon Stereo Test And Demonstration Record that satisfies all of these grueling parameters. Turn your speakers way up, make sure you're right in between them, and listen carefully:
"Well, good luck!"
