Short answer: the Wharfedale Diamond 12.1. It ranks #20 of 71 bookshelf speakers by sound quality at $599; the JBL L52 Classic ranks #49 and costs $1099.95, so there is not much of a tradeoff to weigh.
What the JBL L52 Classic offers: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. 5.25” pure pulp cone woofer and 0.75” titanium dome tweeter on a waveguide, front-firing bass reflex port, in a compact stand-mount cabinet. A pronounced upper-bass bump around 100 Hz gives kick drums a punchy, textured character. Watch for: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume; adding a subwoofer high-pass didn’t fix the high-frequency distortion either. Response rolls off quickly above the upper-bass bump, so there’s punch and impact but not real low-end rumble or fundamental weight below about 60 Hz without a subwoofer. Soundstage width was inconsistent track to track, with imaging not staying locked to where instruments should be. Vocals could sound hot and slightly grainy in the 2.5-5 kHz region; pointing the speakers off-axis reduced that sharpness but also killed high-frequency air.
What the Wharfedale Diamond 12.1 offers: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Wide horizontal radiation of about ±60° up to roughly 5kHz before the tweeter starts to beam. Tonally smooth and easy to listen to at moderate volumes, with a pleasant, non-fatiguing character the reviewer said he’d happily recommend to someone who wants noticeably better fit, finish and looks than typical speakers in the $300-400 range. A high-pass crossover around 80Hz meaningfully cleans up midrange multitone distortion, so pairing it with a subwoofer helps more than usual for a speaker this size. Watch for: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material - possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat. Vertical directivity is unusually tight for this class of speaker, holding together only within about ±5° of the tweeter axis before a real hole opens up in the response, so seating height matters a lot more than on most bookshelf designs. Diffraction artifacts around 3kHz and 5kHz show up as differences between the listening-window and on-axis curves. Distortion climbs well past acceptable levels at higher output - harmonic distortion exceeds 3% around 150Hz at 96dB (versus under 1% at 86dB), multitone distortion tops 10% at 96dB/1m, and real compression sets in between 96-102dB (about 1.5dB of lost dynamic range around 300Hz at 102dB/1m, roughly equivalent to 92dB for a pair at 4m in a room) - a genuine limitation on how loud or how far away this speaker can be pushed. Measured average sensitivity (84dB) runs a few dB below the 87dB spec. Only a 5” woofer, so a subwoofer is required for real bass.
Buy the Wharfedale Diamond 12.1. It ranks higher for sound quality than the JBL L52 Classic and costs less, so there is no real case for the other one.
