Celsus Sound is a sister company to NuPrime and goes in the spirit of NuPrime with lots of good sound for the money.

The SP-One plays very clearly, with authority and you are greeted by a large soundstage that goes a little to the warmer. The speakers themselves are very capable and grow with fine electronics.

SP-One fits equally well in the home stereo as on the desktop.

The Celsus SP-One speaker can fill a room with audiophile-quality sound. The SP-One's expansive soundstage, commanding bass and overall musicality puts it at the forefront of "bookshelf" speakers. And for more personal applications, the SP-One's excellent near field characteristics, especially at low volume settings, makes it the perfect desktop companion. The carbon-fiber woofer, featuring an aluminum waveguide, nicely complements the cabinet's sophisticated styling.

Deep Bass Carbon Fiber Woofer

A carbon-fiber cone woven from thousands of ultra-fine carbon fiber yarn features these advantages:

• The rigidity (Young's modulus) is three times that of glass fiber, twice that of Kevlar fiber, and 20 times the strength of iron. It effectively inhibits split-vibration frequency distortion, resulting in miniscule dynamic deformations.
• Low mass (lighter than aluminum) permits high electro-acoustic conversion efficiency with the ability to closely follow the electrical signal's transient response, with the added benefit of high sensitivity and an impressive SPL.
• Insensitive to changes in humidity and temperature, thus offering excellent stability over long periods of time.
• Patent pending folding ring design - For small and mid size speakers, the traditional folding ring design has a deficiency that resulted in 10dB frequency curve valley in the 2kHz region. This will affect the vocal richness of the music. The Celsus Sound folding ring design solves this dynamic nonlinear distortion problem and improves overall frequency response.

The carbon-fiber cone produces dynamic and powerful bass, smooth, detailed sound and a wide sound stage.
