Moreso, this is information for those who prefer “just the facts” and prefer to have the data without the filler. This is a small volume speaker with a tiny mid-woofer so you have to understand that it can't produce real bass, just harmonics. IEM, headphone amps, DACs, and obviously DAPs, they did it all and did it well, filling each and every corner with an endless list of multi-awarded devices, like the K9 Pro, BTR5 , KA5, or the M17.

With the FiiO SP3, the development team considered multiple aspects when choosing the material of the tweeter. One area where my earlier measurements and Erin estimate do agree is the dip after the 2K region (C). Meanwhile, the Chinese “ 飞傲 ” is the transliteration of FIIO, indicating the positive and innovative spirit as thriving as spring. carbon fiber mid-woofer and an 1″, in-house developed, silk dome tweeter that are powered by two-channel class-D amplifiers from TI, outputting 10W for the highs and 30W for the lows with 100W of total peak power.Sometimes rooms are excessively “dead” as in other styles of décor and in some custom home theaters where acoustical treatment has been used excessively.

All in all, the SP3 will easily immerse you in a movie thanks to its ability to accurately reproduce sound effects. The light weight of carbon fiber allows the woofer to have rapid transient response, while carbon fiber’s high strength and rigidity reduce non-linear distortion by minimizing unwanted secondary vibrations when the driver is moving when producing sound. The SP3's tweeter incorporates a wave absorption structure using silk as the design material, which effectively absorbs unwanted sound waves behind the driver. The crossover and the drivers are well implemented, the sound is coherent and balanced throughout the whole frequency range, bass excluded of course. Build Quality: Quality Meets Compactness​With its “Pressure die-cast liquid metal cabinet” machining, the SP3 strikes a balance between robust construction and sleek design, making it an elegant yet unobtrusive addition to your home office without occupying much-needed space.

The bottom part of each cabinet houses an RGB led stripe that will illuminate the base of it with a pulsing light. Volume - I would have preferred to have the volume on the front but since I am controlling the volume via my computer (and on the Wiim App when using the Wiim Mini) this is not an issue for me. The moment you turn on the SP3, light floods the bottom of the device, instantly transforming the atmosphere of your desktop. Voices are very clear, treble and mid bass are great, the low end bass is not very pronounced after burn in. The lower midrange dip (B) The Estimate In-Room is an algorithm created for speakers in a Room from the Spinorama data generated by the Klippel Near field scanner.

Altogether, the carbon fiber material of the woofer helps to reproduce sound faithfully and lets you be more immersed in your high fidelity listening. Low resonance frequency and high current carrying capacity have always been the goals of those designing high fidelity audio products. I actually have these speakers and I was going to do a quasi-anechoic measurement (more for my own learning / practise) but maybe I won't bother.The DSP proved invaluable, I spent the last few days with this setup while working, enjoying the full rich sound while almost not noticing the speakers due to their compact size. This encompasses those listeners who sit within a typical home theater audience, as well as those who disregard the normal rules when listening alone.
