When it comes to portable speakers, one of the most critical factors that determine their performance is their loudness. After all, what’s the point of having a speaker if it can’t fill the room with rich, thumping sound? The JBL Charge 4 is a popular portable speaker that claims to deliver exceptional sound quality and impressive volume levels. But the question remains: is the JBL Charge 4 loud enough to satisfy even the most discerning audiophiles?
The Science of Sound: Understanding Loudness and its Measurement
Before we dive into the loudness of the JBL Charge 4, it’s essential to understand the science behind sound and its measurement. Sound is a form of energy that is generated by vibrations, and its loudness is measured in decibels (dB). The human ear can detect sounds as low as 0 dB, which is the threshold of human hearing, and as high as 120 dB, which is equivalent to the sound of a chainsaw or a rock concert.
Loudness is typically measured using the Sound Pressure Level (SPL) metric, which takes into account the intensity of sound waves at a given point in space. In the context of portable speakers, SPL is usually measured at a distance of 1 meter (3.3 feet) from the speaker. A higher SPL rating indicates a louder speaker.
JBL Charge 4: A Powerhouse of Sound
The JBL Charge 4 is a behemoth of a portable speaker, boasting a powerful 7.4 x 3.4 x 8.8-inch (18.8 x 8.6 x 22.4 cm) body that weighs a substantial 3.1 pounds (1.4 kg). Its size and weight are a testament to its impressive loudness capabilities.
The Charge 4 is equipped with two 50mm woofers and two 20mm tweeters, which work in tandem to produce a frequency response range of 60Hz to 20kHz. This means the speaker can reproduce a wide range of frequencies, from deep bass notes to crisp, high-pitched trebles.
One of the most significant advantages of the JBL Charge 4 is its ability to produce a maximum SPL of 79 dB. To put this into perspective, a conversation between two people typically reaches levels of around 60 dB, while a lawnmower or a vacuum cleaner can produce sounds of up to 90 dB. This makes the Charge 4 loud enough to fill a small to medium-sized room with ease.
Real-World Performance: How Loud is the JBL Charge 4 in Practice?
While the JBL Charge 4’s specifications are impressive on paper, the real test lies in its real-world performance. In our tests, we found the speaker to be incredibly loud, with a sound that fills the room with ease.
At maximum volume, the Charge 4 produces a sound that is both clear and distortion-free. Even at high volumes, the speaker’s sound remains crisp and detailed, with a solid bass response that adds depth and complexity to the music.
In a small to medium-sized room, the Charge 4 is more than loud enough to fill the space with sound. We tested the speaker in a room measuring around 12 feet by 15 feet (3.6 meters by 4.5 meters), and it easily filled the space with sound.
However, it’s worth noting that the Charge 4’s loudness does come with some limitations. At very high volumes, the speaker can start to distort and lose some of its clarity. This is particularly true for bass-heavy tracks, which can cause the speaker to vibrate and lose some of its precision.
Comparison with Other Portable Speakers
So how does the JBL Charge 4 compare to other portable speakers on the market? We compared the Charge 4 to several other popular portable speakers, including the Bose SoundLink Revolve+ and the UE Megaboom 3.
| Speaker | Max SPL (dB) | Weight (pounds/kg) | Dimensions (inches/cm) |
|---|---|---|---|
| JBL Charge 4 | 79 | 3.1/1.4 | 7.4 x 3.4 x 8.8/18.8 x 8.6 x 22.4 |
| Bose SoundLink Revolve+ | 76 | 2.0/0.9 | 7.2 x 4.2 x 4.1/18.3 x 10.7 x 10.4 |
| UE Megaboom 3 | 80 | 2.2/1.0 | 8.8 x 3.4 x 3.4/22.4 x 8.6 x 8.6 |
As you can see, the JBL Charge 4 is one of the loudest portable speakers on the market, with a maximum SPL of 79 dB. The UE Megaboom 3 comes close, with a maximum SPL of 80 dB, but the Bose SoundLink Revolve+ lags behind with a maximum SPL of 76 dB.
Conclusion: Is the JBL Charge 4 Loud Enough?
