Short answer: the Arendal 1961 Monitor for better sound quality, the Parts Express Copperhead Desktop Kit for the lower price. The Arendal 1961 Monitor ranks #8 of 87 bookshelf speakers at $1150. The Parts Express Copperhead Desktop Kit ranks #65 at $119.98, $1030.02 cheaper.
What the Arendal 1961 Monitor offers: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality - one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Works well both as home theater mains and as surrounds. Independent ASR Klippel measurements corroborate the low-distortion finding: THD at 86dB SPL/1m stays well below the reviewer’s audibility threshold, and even at 96dB SPL/1m it stays “far better than most bookshelves” thanks to the built-in high-pass filter that protects the woofers. Watch for: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well. Vertical radiation window is narrow, typical of MTM (mid-tweeter-mid) layouts - tighter than a standard two-way’s roughly ±20° - so a second home theater row sitting above or below the tweeter axis will hear a noticeably different tonal balance. ASR’s CEA2034 measurements show the response is elevated above 2kHz with resonant peaks around 3kHz and 9kHz, leading the reviewer to predict it will “likely sound bright.” Those same resonances show up as lingering ridges in the cumulative spectral decay (waterfall) at 96dB SPL/1m.
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. 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. 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. 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.
