The dynamic range is the maximum ratio of noise floor to the system output. The dynamic range perceived in human hearing is about 120dB from the loudest to the softest sound. In reality, your home theater systems are not near this level due to high output demands from your loudspeakers. Here is how you can boost you’re the dynamic range of your home theater system by following the steps below.

‘Step 1’
Controlling background noise Flow

Controlling external noise flow to your room can be achieved by ‘insulating the walls, replacing flimsy doors with insulated ones or sealing your doors’ . Minimizing HVAC noise is the most crucial way of reducing the noise floor in the room.

‘Step 2’
Listen closer to the speakers

In large anechoic rooms, sound follows the law of inverse square where it drops for each doubling distance. That is, if your speaker is positioned 5ft vs 10ft from you, it will produce a lower sound. It's crucial to ‘reduce the distances of your speakers and your listener’ . Also, place each speaker directly to the listener. Avoid obstructions like couches and furniture to allow a higher ratio of the reflected sound vs direct sound.

Manage Your Bass

Managing your bass saves your amplifier power by ‘minimizing the power requirement of the bass frequencies’. It can also make the powered subwoofer to handle it. This is important when you are using an AV receiver with a limited power supply.
