Is the DS103 good for music or movies?

It leans toward music. The sealed cabinet keeps bass fast and controlled, which suits music well. For loud movie effects in a large room, a bigger ported sub will hit harder.

Will it match my Debut 3.0 speakers?

Yes. It is designed to complement the Debut 3.0 series and shares its voicing, so it blends naturally with those bookshelf and floorstanding models.

What inputs does it have?

It has LFE, stereo line-level and speaker-level inputs, plus high-level outputs. That covers most AV receivers and stereo amps.

Does it turn on automatically?

Yes. Auto power on/off switches it on when it detects an audio signal and off when there is none.

Is a sealed sub good for home theater?

Sealed subs give tight, accurate bass but less deep output than ported designs of the same size. It works well in small to medium rooms; large rooms may want more.

Can I use two of them?

Yes. Two subs can even out bass across a room, and the flexible inputs make pairing straightforward with most receivers.
