Short answer: the Parts Express Copperhead Desktop Kit. It ranks #26 of 34 bookshelf speakers by sound quality at $119.98; the Jamo S 803 ranks #34 and costs $119.99, so there is not much of a tradeoff to weigh.
What the Parts Express Copperhead Desktop Kit offers: Inexpensive, beginner-friendly CNC flat-pack kit with a compact 8 x 5-inch desktop footprint and only one 3.5-inch full-range driver per channel. Watch for: Despite the ‘full-range’ label, output rolls off around 120-150Hz and a subwoofer with an unusually high 100-200Hz crossover is effectively mandatory.
What the Jamo S 803 offers: Low pair price, compact dimensions and a front slot port suit inexpensive desktop or surround installations. Watch for: A textbook V-shaped response rather than accurate reproduction.
Buy the Parts Express Copperhead Desktop Kit. It ranks higher for sound quality than the Jamo S 803 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 34 bookshelf speakers instead.

Parts Express Copperhead Desktop Kit: $119.98 Parts Express
Pros: Inexpensive, beginner-friendly CNC flat-pack kit with a compact 8 x 5-inch desktop footprint and only one 3.5-inch full-range driver per channel. The point-source layout avoids a conventional woofer/tweeter crossover and, when listened to around 20 degrees above the driver as intended, can produce precise near-field imaging. Erin measured roughly 81dB sensitivity, consistent with Parts Express’s specification. The included baffle-step network improves lower-midrange balance, while the optional series inductor reduces the driver’s rising top end; Erin recommends retaining it. Several remaining narrow peaks can be corrected with desktop software EQ. Bottom porting conserves desk space, and unfinished MDF invites custom finishing.
Cons: Despite the ‘full-range’ label, output rolls off around 120-150Hz and a subwoofer with an unusually high 100-200Hz crossover is effectively mandatory. Native response has resonances near roughly 2.1kHz and 8kHz plus a broad 14-20kHz rise of 5-8dB, so it is not smooth without the supplied network and additional EQ. Distortion already exceeds 3% in places at 86dB/1m and becomes extreme at 96dB. Erin’s multitone test approached -10dB distortion (roughly 30%) full-range at the highest level, accompanied by 3-4dB compression; even a 200Hz high-pass leaves roughly 3-5% distortion and 2-3dB compression. The angled cabinet demands a specific near-field ear height, and its very low sensitivity plus 10W RMS power rating leave almost no clean-output headroom for room listening.

Jamo S 803: $119.99 Amazon Crutchfield
Pros: Low pair price, compact dimensions and a front slot port suit inexpensive desktop or surround installations. The pronounced 80-100Hz hump supplies immediate punch and can sound impressive in a short demonstration. Harmonic distortion at 86dB is broadly typical for an inexpensive 5-inch two-way, and high-passing near 80Hz reduces some woofer-driven midrange distortion. The cabinet also accepts Jamo’s matching top-mounted Atmos module.
Cons: A textbook V-shaped response rather than accurate reproduction. Erin measured only about 81dB average sensitivity from 300Hz-3kHz, far below Jamo’s 87dB claim; bass around 80-100Hz and the treble are each roughly 5dB above that midrange reference. The bass is therefore resonant one-note punch rather than deep extension. Horizontal coverage is only about +/-50 degrees, while the midwoofer narrows before the tweeter widens abruptly, creating a directivity discontinuity that EQ cannot repair around 4kHz. Vertical tolerance is especially asymmetric: roughly 10 degrees above tweeter axis is usable, but moving below it rapidly damages the response. At high output, compression and multitone distortion become audible; an 80Hz crossover helps but does not correct the native tonality. Erin’s conclusion was an unequivocal pass in favor of a more neutral alternative.
