The Onkyo SKS-HT690 5.1 Surround Sound Home Theater System provides realistic, immersive sound in a compact and affordable package. The system has an active subwoofer with a 10" down-firing driver. This design allows you to place the sub in a corner or near a wall without worrying about interference from the wall. The sub has a bass-reflex cabinet design, which helps to extend low frequency response and reduce compression.
The front speakers each contain a 3.25" woofer and a 1" balanced dome tweeter, while the center speaker has a pair of 3.25" woofers and a 1" balanced dome tweeter. This provides a wide frequency response with excellent intelligibility for clear vocals, music and sound effects. The rear speakers each have a 3.25" woofer to provide full-range audio for detailed surround effects.
