Lastly, let’s get technical, with jargon and what-haves to see what makes a speaker sound louder or better.
Tweeter and Woofer: Really the only two apparatus in a speaker model you need to know. The tweeter helps produce high-pitched sounds (treble and vocal), and the woofer punches up low-frequency tones (the bass and boom).
Usually, for both the tweet and woof, the bigger size, the better—meaning they’ll be able to disperse the sound more widely. This is especially true when it comes to bass, giving it a real nice depth. That’s why Bowers & Wilkins’ weatherproof AM-1 and Klipsch’s AW-650—each has large woofer and tweeter—can really populate the airwaves with hardcore bass, and why small Bluetooth speakers often can’t outbid dedicated outdoor speakers in sound quality or audio power.
Frequency Response: This one, most consumers don’t need to know much about, but audiophiles love it. A very dumb explanation is this: It’s the range in which your speakers will output sounds within a few decibels of the desired input. A lot of brands don’t even give you a standard deviation, so it’s not as informative as it should be. All you need to know is that 20Hz to 20kHz is the range of sounds that humans can hear. As close to that as possible will give you reliable sound. Any data about sounds below or above 20Hz and 20kHz… you literally will not hear it.
