With the SP3, FiiO unveils compact and powerful active speakers, ideal for a desktop installation as well as for integration in a living room for example. These two-way powered models provide a high quality sound reproduction, both accurate, rich and dynamic. Each point has been carefully thought out and adjusted to provide the best sound performance and promote a beautiful immersion.

Asymmetrical internal and external magnetic circuits

In order to allow the 3.5" woofer to act efficiently and to allow the SP3 to deliver its full potential, FiiO engineers have developed a system of external and internal asymmetrical magnetic circuits. An auxiliary magnet was added to the center of the SP3 to improve the strength of the magnetic field and reach a 1.2T magnetic flux. It is thanks to this important driving power that the SP3 manages to provide such a dynamic sound. Moreover, this particular structure allows a certain reduction of the non-linear distortion on the whole frequency band.

Directional waveguides

In order to offer excellent sound quality, the FiiO SP3 has been perfectly designed and adjusted to ensure that the sound waves reach the listener in an optimal way. The tweeter is positioned to allow for high quality listening without requiring extremely precise and constraining speaker placement. In addition, the horizontal bands surrounding the tweeter allow for a wide dispersion of the sound waves, greatly improving the sound image.

Active 2-way crossover

The SP3 adopts an active 2-way crossover with a 3.4kHz cutoff frequency, specifically designed to maximize the performance of the tweeter and woofer. The ingenious integration of this crossover circuitry ensures a reduction in intermodulation distortion, avoids overloading the drivers and greatly improves the speaker's performance..
