Looking for an extremely loud speaker, with an exceptional sound quality that you can tweak to your heart’s content, and revel in outdoors or indoors? JBL Boombox is much more rugged than the Exos-9 and it’s actually waterproof ( IPX7). If you need something that you can take with you wherever you go, JBL Boombox is a much better option.

Aiwa Exos-9 is a nice-looking and quite large Bluetooth speaker. It’s portable and you can use it outdoors but be aware that it’s not rugged or waterproof. Another awesome-looking portable Bluetooth speaker is the Sony XB90. The XB90 is the loudest Bluetooth party speaker from Sony. It comes with an array of LED lights, including a strobe effect, to add some party ambiance. In addition, the speaker comes with audio effects for the microphone input. This makes the XB90 great for karaoke parties. Audio Connections After 15 minutes of inactivity, the speaker enters sleep mode to save power. In sleep mode, the speaker will not connect via Bluetooth or play audio.Using something like output wattage as a metric is flawed because it doesn’t take into account the efficiency of the speaker design. We also wanted to make sure we don’t recommend speakers that we can’t truly stand by, so we excluded products that offer poor quality or specify volume measurements that aren’t supported by the actual performance. When it comes to sound, we prefer Exos-9. It delivers much fuller, richer, and more powerful sound than the SounndTouch 30. You can choose the double stereo mode (LR + LR) where each speaker reproduces the same sound. Alternatively, choose the separated-stereo mode (one speaker acts as the left (L) and the other as the right (R). In the end, the only thing that matters is what you need. If you need a powerful, loud, rich, and well-balanced sound, Aiwa Exos-9 is one of the best choices. Exos-9 is portable, it has a large battery, and can be used outdoors but it’s not rugged enough or waterproof. If you need something that you can use by the pool, Exos-9 is not the right choice. Indoors, no matter the room size, the Exos-9 produces a room-filling sound that is balanced and rich. It’s so good you could even consider using it for your home theater setup.

Aiwa Exos-9 is a battery-operated speaker. The battery is not built into the speaker and it can be removed and replaced. There are many factors that affect the volume of a speaker. Looking at the wattage alone might give you an idea of a speaker’s potential volume (a 400W speaker will definitely be louder than a 5W speaker) but make sure you are comparing the RMS wattage instead of peak power. Do More Decibels Mean Louder? The USB powebank port can be used for charging phones or tablets. Assuming that the capacity of the battery is 15,600mAh, you can fully recharge Samsung S9 or iPhone X 5 times.

We noticed that a lot of online lists with the loudest Bluetooth speakers available were simply not correct. We approached this article with measurements in mind; we wanted to build a list of truly the loudest Bluetooth speakers available on the consumer market. We looked at how these speakers performed in terms of decibel measurements. An improvement Aiwa could make to the front screen is to add a volume level indicator and a battery status indicator. And too, if you’re looking for a more modern speaker with features like AirPlay, Google Cast, voice assistants, and Spotify built-in, you’ll have to look elsewhere. Let’s Talk About the Equalizer Something interesting to note is that a decibel in itself does not tell us anything unless you assign it to something – such as SPL (Sound Pressure Level). We are so used to using decibels as a measurement of sound or music loudness that we would assume that that’s what dB stands for, but the decibel actually needs to be assigned to a unit to mean anything. Interesting, right?

I’ve already talked plenty about the design but let’s go through in detail the controls for this beast. The Front Aiwa Exos-9 – Front Panel and Display The sound quality is what made Aiwa Exos-9 so popular but it’s not the only good thing about this speaker. The battery inside the speaker is pretty good (but there are some confusing things about the battery we are going to discuss). We also liked the facts that Exos-9 features USB powerbank port for charging phones/tablets and that you can customize the EQ settings by using onboard EQ controls. Exos-9 can be paired wirelessly with another Exos-9 speaker and you can choose between 2 modes – dual stereo and stereo separated (we are going to explain these two modes later). No matter how high you turn up the volume, there is almost no distortion (less than 0.1%) even if the table it’s on is shaking. This is especially impressive for a battery-operated speaker. It’s a sound you would expect from a more expensive in-home speaker. This calculation should be considered as a guide, but because the efficiency of speakers varies, one can’t accurately calculate the specific decibels from a provided wattage. Speaker Efficiency vs. SensitivityAudiophiles don’t have to worry about sound quality and surround sound. You can even connect two Aiwa Exos-9 speakers for a more powerful and surround-quality sound system. You can configure them as dual stereo or stereo-separated depending on your needs. Host a large party and keep them entertained with high-quality surround music. The PartyBox 1000 comes with more features than you’ll find on any other portable party speaker on the market. These include wireless Bluetooth streaming, a full LED light show, and microphone and instrument inputs for your karaoke parties. Audio drivers – Look for speakers which have at least 4 or 5 audio drivers. Dual-coil subwoofers that measure more than 5 inches are recommended.
