Fiio SP3 Powered Speaker. Demo, used in store, boxed, in great condition
Heavy compact speakers thanks to the metal enclosures. Very surprising bass response from their compact size, should be shockingly full in an average size room, on a desk. Analog input only - meant to connect to a dac, like a Fiio KA11 for instance.
True audiophile quality - 3.5-inch carbon fibre mid/bass driver
The FiiO SP3 features a 3.5-inch carbon-fibre mid-woofer that is larger than comparable products in its class. These larger woofers have an inherent advantage over smaller woofers in terms of dynamics, projection of a larger soundstage and other sonic characteristics. Whether for movies or music, this woofer is capable of expressing the grandeur of sound even at higher volumes.
Carbon fibre is extremely strong and rigid, yet lightweight - the ideal properties for a speaker driver. The light weight of carbon fibre allows the woofer to transient quickly, while the high strength and stiffness of carbon fibre reduces non-linear distortion by minimising unwanted secondary vibrations as the driver moves during sound production. Overall, the woofer's carbon fibre material contributes to faithful sound reproduction and immerses you even deeper into your high-fidelity experience.
Each carbon fibre in the SP3 is just 0.007mm thick - the thickness of a single hair. These fibres are interwoven, which helps improve sound quality by ensuring a wrinkle-free diaphragm and making the diaphragm stronger and more resistant to cracking after prolonged movement and use of the driver.
Hear the dynamic air vibrations - Even between the strings - 1-inch silk tweeter.
In an active desktop speaker, the tweeter often plays a crucial role in reproducing fine musical detail, instrumental harmonics and overall treble resolution. Unlike many other active desktop speakers that use a ¾-inch tweeter, the SP3 uses a 1-inch tweeter that can produce frequencies up to 35 kHz.
The tweeter's copper-clad KSV aluminium voice coil ensures that ultra-high frequencies are not compressed, even at high volumes - resulting in improved high-frequency response even with off-axis listening, and high-resolution highs with a natural timbre. With the SP3, you'll be able to hear even the subtlest vibrations of instruments.
Robust performance - Always at hand - Asymmetrical internal and external magnetic circuits
To ensure that the 3.5-inch carbon-fibre midwoofer produces truly powerful bass and that the SP3 can deliver its full potential, the design team created an asymmetrical system of internal and external magnetic circuits. An additional magnet has been placed in the centre of the SP3 to form an internal and external magnetic circuit, which improves the strength of the magnetic field generated and allows a magnetic flux of up to 1.2 Tesla.
This is the powerful driving force behind the driver that gives the SP3 its dynamic sound. In addition, the asymmetrical internal and external magnetic circuit systems help reduce non-linear distortion across all frequencies, so good sound is always available, no matter what music you listen to.
