#20 Fiio SP3: $299.99 per pair Amazon eBay
Pros: Compact cabinets and angled bases fit a small desk. The existing review found useful dynamic capability at higher frequencies, so lack of output is not the only issue. Erin’s Klippel data shows a measured -3dB bass point around 60Hz, deeper than several similarly sized alternatives. Measured bass extension of 59Hz (-3dB).
Cons: The response rises strongly toward the treble, about 1.13dB per octave, with a recessed midrange and problematic crossover behavior. Its 3.56 standalone and 6.17 ideal-subwoofer scores do not capture the full practical impact of the review’s boomy bass and off-axis tonal problems. Changing angle trades one coloration for another. Those audible limitations weigh against it more heavily than its numerical score or build quality.
How it compares: Just above it: Fluid Audio C35BT - $161 cheaper, 24W more output power. Just below it: M-Audio BX3 - $211 cheaper, 10W more output power.
