How to Make Bluetooth Speaker Louder

Does your Bluetooth speaker sound quieter than you expected? You’re not alone. Many users are disappointed when they connect their speaker and notice the maximum volume is insufficient. The good news is there are several tricks to make your Bluetooth speaker louder without buying a new one. In this article I’ll explain them all, from phone settings to physical placement.

Phone settings to increase Bluetooth volume

The first thing you should check is your phone’s audio settings. Many times the problem isn’t the speaker but the phone itself limiting Bluetooth output volume.

On Android:

• Go to Settings > Sound & vibration > Volume. Make sure media volume is at maximum.
• Enable Absolute Volume: Settings > Developer options > Disable “Absolute Volume.” This separates the phone’s and speaker’s volume controls.
• Disable any safe volume limit if it exists on your model.

On iOS:

• Go to Settings > Sounds & Haptics > Headphone safety.
• Disable “Reduce loud sounds” if it’s enabled.
• Adjust the maximum volume limit if it exists.

Pro-tip: On Android, the developer options menu is your best ally. If you don’t have it enabled, go to Settings > About phone > Tap “Build number” 7 times to unlock it. Inside you’ll find Bluetooth audio settings not available in the normal menu.

Use an equalizer to optimize sound

An equalizer lets you adjust audio frequencies to get the most out of your Bluetooth speaker. Simply turning up the volume isn’t the same as optimizing the sound so it feels more powerful and clean.

Recommended equalizer apps:

Wavelet for Android is my favorite because it has automatic profiles for thousands of headphone and speaker models. You simply select your device and the app adjusts frequencies to correct that specific model’s deficiencies.

Slightly boosting low frequencies (bass) and upper-mids (presence) usually gives a feeling of greater volume and power without too much distortion.

Place the speaker in the correct position

The physical position of a Bluetooth speaker has a huge impact on perceived volume, and most users overlook this.

Placement rules:

• Against a wall: Place the speaker less than 30 cm from a solid wall. Sound reflection can increase perceived volume by up to 30%.
• In a corner: A wall corner amplifies sound even more, especially bass.
• On a solid surface: Avoid hollow tables or soft surfaces that absorb sound. A solid wood table or the floor is better.
• Speaker facing you: Make sure the speaker points toward where you are, not toward the wall or ceiling.

Pro-tip: A trick that works surprisingly well is placing the speaker inside an open cardboard box or a ceramic pot. The container acts as a natural sound box and noticeably amplifies the sound. It’s not elegant, but for a backyard barbecue it’s perfect.

Update the speaker’s firmware

Many Bluetooth speakers receive firmware updates that improve audio performance, including maximum volume and sound quality.

How to update:

1. Download the manufacturer’s official app (JBL Connect, Sony Music Center, Marshall, Bose Music, etc.).
2. Connect the speaker via Bluetooth to the app.
3. Look for the “Update” or “Firmware” option in the app’s settings.
4. If an update is available, download and install it.

In my experience with JBL and Sony speakers, firmware updates have improved both volume and sound clarity. It’s one of those things people forget to do that can make a real difference.

Physical limitations of Bluetooth speakers

It’s important to be realistic: a Bluetooth speaker has limits. No software trick can overcome hardware limitations.

Factors that limit volume:

• Amplifier power: Measured in watts (W). A 10W speaker will never sound like a 50W one.
• Driver size: A 40mm driver produces less volume than a 70mm one.
• Cabinet design: Sealed cabinets usually have more controlled bass but less volume than bass reflex ported designs.
• Battery capacity: At maximum volume, the battery drains much faster.

If your Bluetooth speaker simply can’t push any further, consider investing in one with higher power. Models at 30W or more offer plenty of volume for most outdoor situations.

Bluetooth audio codecs: quality matters

Not all Bluetooth audio is equal. The codec your connection uses directly affects sound quality and, to a lesser extent, perceived volume. Many users don’t know which codec they’re using or how to change it.

Bluetooth codec comparison:

SBC is the default codec and the one most cheap speakers use. It compresses a lot and loses detail. If your speaker and phone support aptX or LDAC, enabling them makes a noticeable difference in clarity and volume.

On Android: Go to Settings > Developer options > Bluetooth audio codec and select the best available.

Pro-tip: If you use a cheap speaker that only supports SBC, don’t complicate yourself with codecs. Focus on equalization and physical placement. High-quality codecs only make a difference on speakers and headphones that can actually reproduce them properly.

Pairing two speakers: double volume without distortion

If one speaker doesn’t give you enough power, the cleanest solution is connecting two. Most manufacturers allow pairing two speakers of the same model for stereo sound or Party Mode.

How it works by brand:

• JBL (PartyBoost): Open the JBL Connect app, tap the PartyBoost icon, and bring the second speaker close. They pair automatically.
• Sony (Party Connect): From the Sony Music Center app, select “Connect multiple speakers” and follow the instructions.
• Marshall (Stack Mode): In the Marshall app, look for “Stack” and pair up to two speakers.
• Bose (Stereo Mode): In the Bose Music app, enable stereo mode between two compatible speakers.

The result is impressive. It’s not just louder, but the stereo sound creates an immersive experience that a single speaker can never match. For outdoor parties or large gatherings, it’s the best investment you can make if you already have a decent speaker.

FAQ: Frequently asked questions

Is it bad to use a Bluetooth speaker at maximum volume?

Using it at maximum volume continuously can damage the drivers over time and accelerate battery wear. It’s better to use it at 80-90% maximum to extend its lifespan.

Why does my Bluetooth speaker sound quieter than wired?

Bluetooth transmission compresses audio, and some codecs (like SBC) lose quality and volume. If your speaker and phone support high-quality codecs like aptX, LDAC, or AAC, enable them for better sound.

Can I connect two Bluetooth speakers for more volume?

Yes, many manufacturers allow pairing two speakers of the same model for stereo sound or Party Mode. JBL, Sony, Marshall, and Bose offer this feature in their official apps. It’s the most effective way to double volume without distortion.

Do Bluetooth speakers with WiFi sound louder?

Not necessarily louder, but with better quality. WiFi allows transmitting audio without Bluetooth’s compression, so the sound is richer and more detailed. But maximum volume depends on hardware, not the connection protocol.

Conclusion

Making your Bluetooth speaker louder is a combination of phone settings, physical placement, equalization, and if necessary, firmware updates. You don’t always need a new speaker; many times the problem is in the configuration. Try the tricks in this article and you’ll notice a significant improvement. And if after all that you still need more power, then it’s time to consider upgrading to a model with higher output.
