Yes. From the factory it is set to run at around 50% of max volume to preserve battery power... but if you go to menu section 14.4 and set Audio Boost: ON
This opens up the internal amps to being able to use their full maximum power.
Now that said, one cannot realistically reproduce bass and volume levels equally when comparing to a sound source that is so close it is physically in your head vs having it in a small size limited speaker.
Also, even without the audio boost turned on, I have played in restaurants with 50+ people and no one had any issues hearing me clearly... if you are needing more volume to clearly hear that level of sound, I would respectfully ask you to see a hearing specialist.
