Do I need a subwoofer with the Ultra Bookshelf?

For most music, no. Its low-frequency extension is deeper than typical bookshelf speakers. For home theater explosions, a subwoofer still adds the lowest octave.

Can I use it as a center channel?

Yes. It is designed to work as any channel in a surround setup, including center and surrounds. Keep it upright and at ear height for the best result.

What amplifier power does it need?

It benefits from a clean amplifier with real power rather than a low-wattage mini amp. A modest stereo receiver or integrated amp is enough for normal rooms.

How does it compare with the previous Ultra model?

The current version keeps the same bass-forward, detailed character. Changes are incremental rather than a redesign, so upgrading from the last generation is not essential.

Is it good for near-field desktop use?

It can work on a desk, but the deep bass and wide imaging suit a room better. On a desk, pull it away from the wall and keep volume moderate.

What is covered by the warranty?

The 5-year unconditional warranty covers the speaker, and the Bill of Rights coverage adds further protection. Keep your proof of purchase for claims.
