FiiO - SP3

The FiiO SP3s frequency response curve is essentially a straight line in the test and is smooth with balanced bass, mids, and treble. It is important to note that the effective bass extension can go as low as 65Hz, practically unheard of for its class. The FiiO SP3s sound stimulates every auditory system nerve when you watch films or listen to ultra-low-frequency music. Thanks to the 1-inch tweeter unit, there is no drop in the 10k–20kHz frequency band in the high-frequency region, maintaining the curve's smoothness and straightness and accurately reproducing what a HiFi speaker should sound like.

The FiiO SP3 was specifically tuned and created for outstanding sound quality, ensuring that the sound waves reach the listener in the best possible way. You don't have to be listening at a specific position because the tweeter is precisely angled to virtually eliminate sound wave loss for listeners at an off-axis range between 0 and 15°, making it easier to place the speakers where you want them. Additionally, the horizontal striped pattern in front of the tweeter is intended to improve the soundstage perception and give the impression that you are actually in a large concert hall by allowing the tweeter's sound waves to diffuse more effectively throughout the space.

The bass woofer and the porting tube in a ported speaker reproduce the resulting bass frequencies. The "porting tube" further improves bass extension allowing quick bass transients and overall impactful bass quality. FiiO engineers finally developed the innovative "double-diffused S-shaped porting tube", which specifically allows the SP3 to produce high-quality sound. This porting tube design features a much smaller cross-section than typical porting tubes, allowing the SP3 to remain small in volume. FiiO engineers carefully created the "S" shape of the "porting tube" to maximise smooth airflow and minimise distortion. Finally, damping at the inlet and outlet of the tube reduces audible noise resulting in a phenomenal bass response.

The FiiO SP3 adopts an active crossover with a crossover 3.4kHz specifically chosen to maximise the performance of the tweeter and woofer. The SP3 utilises a 2-way, second-order active filter circuit to precisely control the crossover frequency and ensure that the signals sent to each driver are more effectively isolated. This design consideration reduces intermodulation distortion, prevents driver overload, and significantly increases the use efficiency of the power. You can experience an exhilarating sound unmatched in its class thanks to the SP3 power supply's astounding 100W of output.

Appearance matters when it comes to something that will be displayed prominently on your desktop. For this reason, the FiiO SP3 has LED lights at the base of its cabinet. The moment you turn on the SP3, light floods the bottom of the device, instantly transforming the atmosphere of your desktop. The SP3 will automatically enter a pulsing light mode when in use. It cycles through its 24 different colours.

As standard practice in professional audio and to ensure a better near-field listening experience, the tweeter should be at ear level, and the tweeter axis should be within 15 degrees of the ear. Thus, FiiO specifically developed an exclusive stand with a 7-degree elevation angle for the SP3. FiiO performed listening tests with 5-15° and 7-15° stands with the listener 1 to 1.2 metres away from the speaker. Through these tests, engineers at FiiO felt that a stand with a 7-degree elevation angle would provide the most accurate sound for near-field listeners. Furthermore, it is made of silicone, which acts as a shock absorber by being a soft surface between the SP3 and the desk, reducing sound impurities due to vibrations when the speaker is producing sound.
