Short answer: the Parts Express Copperhead Desktop Kit, if you are buying new. The JBL Studio 530 ranks higher than it (#85 vs #142 of 179 bookshelf speakers, 3.3/5 vs 2.5/5) but is discontinued, so only consider it used; the Parts Express Copperhead Desktop Kit is still sold new at $119.98.
The JBL Studio 530 is the more accurate, deeper-bass pick. Compact bookshelf speakers with a PolyPlas cone woofer and a fairly flat direct response. Its measured preference score, a predictor of how neutral it sounds, is 5.21 against 2.11 for the Parts Express Copperhead Desktop Kit. Its bass reaches about 73.2Hz before falling 3dB, against 98.1Hz for the Parts Express Copperhead Desktop Kit. Watch for: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz.
The case for the Parts Express Copperhead Desktop Kit: An inexpensive beginner flat-pack desktop kit with one full-range driver per side, made for near-field listening with a subwoofer. The catch: Despite the ‘full-range’ label, output rolls off around 120-150Hz and a subwoofer with an unusually high 100-200Hz crossover is effectively mandatory.
Buy the Parts Express Copperhead Desktop Kit new; the JBL Studio 530 is no longer sold new, so it only makes sense as a used find.
