Full-range speakers are designed to produce the entire range of audible frequencies, from low bass notes to high treble notes. They are typically used for the front left, center, front right, surround left, surround right, rear left, and rear right channels. On the other hand, subwoofers are specialized speakers that focus on producing low-frequency sounds, typically below 80 Hz. They are used to add depth and rumble to the audio experience, making it feel more realistic and engaging.
Channel Configuration
In a 7.2 channel setup, the seven full-range speakers are typically configured as follows:
- Front left and right speakers
- Center channel speaker
- Surround left and right speakers
- Rear left and right speakers
The two subwoofers can be placed in various locations, depending on the room’s acoustics and the listener’s preferences. Some common placement options include:
- Placing one subwoofer near the front of the room and the other near the rear
- Placing both subwoofers near the front of the room, one on either side of the front speakers
