#26 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.
How it compares: Just above it: JBL L52 Classic - $980 more, 4Hz higher bass extension (-3dB). Just below it: JBL Stage A120 - $179 more, 2Hz higher bass extension (-3dB).
