Bass, I Love You
Bass, I Love You is a popular bass test by Bassotronics. It is about 3 minutes and 48 seconds (3:48) long. Bass, I Love You begins by two bars of the piano playing solo, then the synthesized bass track begins playing with the repeating piano riff, which continues throughout the entire track. The bass remains at a relatively constant frequency, except for between each bar, at which time there is a sub-audible frequency note under 10 Hz.

Woofer Cooker
Woofer Cooker is a popular bass test by Bass Hit. It is 4 minutes and 10 seconds (4:10) long. It begins with a declining frequency sweep, then it is just a low frequency tone for about 10 seconds with a standard synthesizer playing. Then it goes into a repeating musical progression in the style of rap/hip-hop. Some lyrics are included in this test, such as "feel the bass," which refers to the way audio frequencies below about 120 Hz can be felt as well as heard.

Eminent Technology rotary woofer bass test
This is a bass test by Eminent Technology which was designed to test the ultra-low frequency response of rotary woofers. It is about 3 minutes and 8 seconds (3:08) long. This test consists solely of low frequency tones played at the frequencies of first, third and fifth position notes, as well as subharmonics. The majority of the tones played in this test are infrasonic (below 20 Hz).

Danger
Many conventional subwoofers do not respond very well to infrasonic frequencies. If a test is played at high signal levels, it may damage or destroy conventional loudspeakers, even if nothing can be heard. In a ported subwoofer enclosure, the drivers may be driven past their maximum excursion, due to the lack of back pressure below certain frequencies – they may bottom out and suffer mechanical damage. In a sealed enclosure, the drivers will not move as much because of the back pressure in the box (which will greatly reduce the risk of mechanical damage), but a strong amplifier signal can still damage them by overheating the voice coil.

肥大形容 例如機關槍定點心口位時，低頻像保齡球般打埋黎

又例如鼓皮尾音有冇過重過多、拖尾太長引致聲音模糊等……

有冇過量一睇蝙蝠俠3就知！
