Unfortunately, this is not totally possible considering the fact that most people do their shopping online. Worse of all, some online shopping malls will not even allow you to have a full grasp of what you are buying until the purchase is completed. How then, do I get to test what I am buying to know if it is loud or not, you are asking? Relax, I have you covered.

What is the Loudest Portable Bluetooth Speaker?

Reading through this article will help you know what to look out for and how to check if the speaker you are buying is loud enough as I will be sharing with you factors I put into consideration before choosing Devialet Gold Phantom as the loudest speaker.

Devialet Gold Phantom unlike any other portable Bluetooth speaker offers a number of tonal and textural variations even down at the limits of its extension and displays ballet-slipper poise to go with the iron-glove impact. Its brick-cracking bass alongside a hectic flurry of movement from the side-firing woofers and the alarming visual driver extension is enough leaps to reinforce my choice.

However, factors that contributed to our choice of the loudest speaker include but are not limited to the sensitivity of the speaker, its amplifier power, its wattage, its impedance, its frequency response, its power handling, and Signal-to-Noise Ratio but since not everyone is familiar with what these speakers’ symbols represent, they are briefly explained below.

  • Speaker sensitivity

Sensitivity is an often overlooked yet important specification that should be considered in a speaker before rating the speaker to be loud or not. It is usually shortened to “SPL” and is measured in decibels (Db). An average speaker should come with a speaker sensitivity of about 88 dB to 89 dB on the minimum. 

This is basically what determines the loudness of a speaker, of course, coupled with a few other things like the amplifier power and wattage but majorly, sensitivity rating determines whether or not the speaker will be loud. For instance, if two speakers have the same amplifier power output, choosing the one with the higher sensitivity rate will be the best choice or if two speakers have the same sensitivity rating, the one with a higher wattage should be considered. 

Usually, the combination of high sensitivity and high power output will make a very loudspeaker. In essence, whether in an echoing or non-echoing environment, the sensitivity of a speaker determines its loudness.

  • Wattage (W)

Also known as power handling, wattage is the sheer power that backs up a sound. The higher the wattage, the higher the sound the speaker will produce. It is the wattage that tells the amplifier output power. In other words, the strength of a speaker’s amplification is told by the number of set wattage that the speaker possesses. 

However, every speaker has its own set of wattage. As such, the rate of a speaker’s wattage may not be enough to judge the loudness of the speaker except it is considered in the context of other factors. For instance, a speaker with 100W may not be as loud as a speaker with 50W. This is not because the number of wattages is not strong enough but because a speaker combines high sensitivity and lower power wattage together, its loudness will be awesome and vice versa. For instance, a speaker with 1000-Watt and 85dB sensitivity will not be as loud as a speaker with 300-Watt and 93dB sensitivity.

  • Impedance

This is the effective resistance or the measure of the total opposition that the speaker presents to its audio signals. It is measured in ohms. The amount of current a speaker will draw will also determine its loudness. However, the speaker’s impedance should neither be too high nor too low. 8 ohms is the average standard measure for any speaker that will produce a great sound. An optimum impedance is the best.

  • Frequency response

Measured in Hertz (Hz), frequency response is what tells how high and low a speaker can play. The lower the number of the frequency response, the deeper the bass and the higher the treble the speaker will produce. However, any speaker that will be considered the loudest should not have more than 50 Hz or its sound quality will be distorted.

  • Signal-to-Noise Ratio (SNR)

The higher the number of SNR, the better the sound of the speaker. Signal-to-Noise Ratio (SNR) measures the level of noise that is in the sound produced by a speaker.

  • Size

It is not enough to have a loudspeaker, the size should also be considered. If it is loud and big then, the aim is not achieved. The portability of the speaker tells how mobile it can be although the bigger the size of the speaker, the louder it can be.

Based on the factors explained above, Devialet Gold Phantom has been considered the loudest portable Bluetooth speaker. The speaker has a complicated architecture design and crowd-pleasing numbers with a spherical, omnidirectional nature which makes positioning is quite easy. Its mysterious look, however, does not affect its sound production considering the low-frequency speed, punch, and maneuverability it displays. 

Its power output quality of sound and “loudness” is enough to make it come first on the list. Devialet Gold Phantom, though a wireless speaker, is capable of peak volume levels. In addition, it has in its possession, 4500 peak watts enhanced by 108 patents, a titanium tweeter that offers a frequency range of 14Hz to 27kHz, and 108 dB speaker sensitivity. It is branded ADHV2 and it combines Class A and Class D amplification.

Beyond its properties, it also offers a wide range of benefits to its user. Such benefits include access to web radio, its ability to connect with Wi-Fi, Bluetooth, AirPlay, and Spotify to mention but a few. It also has a digital optical socket for legacy equipment and an Ethernet connection especially in case you are one of those who value signal stability over decorative minimalism. The speaker can be configured to work as stereo pair or a surround-sound cinema package and has the tendency to prevent its own terminal damage. Needless to say that the speaker is easy to set up and simple to use and of course, to enjoy the numerous offers it has in its possession, there must be a price tag. Check it here 

Other Loud Speakers

However, since everyone has their choice of what they call unique, a few other options have been added to include:

1.  SoundBoks (Gen 3) is considered the loudest by some online stores considering its components such as 40 hours playback per charge and features, Bluetooth 5.0 for a smooth connection between your device and the speaker, 10-inch 96dB woofers, and a 104dB compression driver tweeter. Its big and bulky nature has, however, made it unfit to be categorized as the loudest portable speaker since it is not only about the sound but also, the size.


2.  Marshall Woburn II has a good sound quality possessing center and front vocals, good bass punch, two subwoofers, a bass reflex system, brilliant for indoor use, Bluetooth connectivity technology with stereo audio output mode but its giant design disqualified its categorization as the loudest portable speaker.


3.  JBL Boombox 2 with its loud, obnoxious, double tape deck, radio dial, two subwoofers, 30-watt output, correct bass punch, 100dB sensitivity, IPX 7 rating, strong battery life, and cheap price would have ranked the loudest portable Bluetooth speaker, unfortunately, large frame and weight is a deficiency.


4.  Anker Soundcore though portable and possesses a rubber exterior that makes it water and dustproof, easy to grip, has large branding, IPX-7 rating, exceptional battery life, good and clear mid-range frequency sound, two 6-Watt drivers 12-Watt output, and is more suited for smaller events and gatherings cannot make the rank because of its lack of good bass punch and bottom end which makes music to sound a little thin..


Speakers are one important determinant of the overall sound quality one can get and have been considered the loudest based on the afore-explained factors. However, note that, that a speaker is loud, is not enough to guarantee you a nice experience listening to your music. Hence, I’ll advise you not to listen to music based on how loud it is. Instead, consider buying the best setup you can afford. Meanwhile, note that factors such as the environment where your speaker will be used can tell so much about the features of your speaker. For instance, the acoustic properties of the room where your speaker will be used can influence the loudness and the sound quality of your speaker. All the best with your final choice.
