Short answer: the ADAM Audio D3v. It ranks #3 of 47 powered bookshelf speakers by sound quality, rated 4.5/5, at $349.99. The Fluid Audio C35BT ranks #34, rated 3.0/5, at $139, $210.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The ADAM Audio D3v is the more accurate option. Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Its measured preference score, a predictor of how neutral it sounds, is 5.37 against 2.57 for the Fluid Audio C35BT. Watch for: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height.
What the Fluid Audio C35BT does well: Balanced TRS inputs, Bluetooth, front volume control and a headphone output make this inexpensive pair practical for a basic desktop setup. It keeps a wired aux input, which the ADAM Audio D3v lacks. The catch: Preference scores of 2.57 standalone and 5.57 with an ideal subwoofer indicate that the limitations are not just missing bass.
Buy the ADAM Audio D3v. It is rated higher for sound quality, and the $210.99 saving on the Fluid Audio C35BT is not enough to make up the difference.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

ADAM Audio D3v: $349.99 per pair Amazon $349.99 eBay
Pros: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile Little British Monitor. Predicted preference scores of 5.37 standalone and 7.59 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.

Fluid Audio C35BT: $139.00 per pair B&H Photo Video $139.00 eBay
Pros: Balanced TRS inputs, Bluetooth, front volume control and a headphone output make this inexpensive pair practical for a basic desktop setup. ASR’s measured -3dB point is about 78Hz, so it covers more upper bass than the shallowest-reaching mini speakers.
Cons: Preference scores of 2.57 standalone and 5.57 with an ideal subwoofer indicate that the limitations are not just missing bass. Listening-window narrow-band deviation of 0.555 and sound-power deviation of 0.657 show that response irregularities affect both direct and room-reflected sound. A subwoofer cannot correct those tonal problems, and the small drivers are not a basis for expecting high clean output.
