Doesn't yours have a volume control ?
The same comment would apply to a soundbar of similar power using loudspeakers of similar efficiency.
Normally if it sounds very large it's down to a cheap amplifier introducing horrendous amounts of dynamic distortion into a poor speaker system.
Try listening to say a brass band in the street, it won't be specatulary loud. Now replay a similar source over your home system to a similar level, the nearer it sounds to the original the better the quality.
Listen to the sound of distant thunder on a good system you will find it hard to tell which is real and which is recorded (dynamic range).
Modern tiny speakers paIred with a seperate bass speaker (subwoofer) are capable of amazing sound. The comprimise in building these tiny designs is lack of acoustic efficiency (they take a lot driving). A tiny satellite speaker driven at say 60W RMS will sound a lot quieter than a large reflex enclosure paired with just a 15W RMS amplifier. That's the reason why AV amps have big power outputs, mine has 170W over 5 channels. It's not any any louder in Stereo mode than an old decent Leak amp is when driving big floor standing speakers.
You won't ever see the audience duck as the zeros in Pearl Harbour scream over your head in Pearl Harbour using a sound bar (not a recommendation for the film, it's generally rubbish), but the attack sequence on Pearl Harbour and the subsequent bomb exploding in the Arizona's magazine is pretty amazing if you have decent audio kit.
