Short answer: the Polk Audio XT15. It ranks #28 of 74 bookshelf speakers by sound quality at $179; the JBL L52 Classic ranks #52 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 Polk Audio XT15 offers: Very low $179/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Directivity spread is reasonably even for the price (directivity_spdi_stddev 3.60). Watch for: Bass rolls off earlier than most of this batch at 77.6Hz (-3dB) / 54.2Hz (-10dB). On-axis deviation is the roughest measured figure here (aad_on_axis 0.449), and listening-window smoothness (0.303) trails the pricier options in this group. Modest 86dB sensitivity wants a reasonably powered amp channel. The 5.25” bi-laminate paper woofer is Polk’s entry-tier driver, not the polypropylene/Turbine cones used in its pricier Signature Elite/Reserve lines.
Buy the Polk Audio XT15. It ranks higher for sound quality than the JBL L52 Classic and costs less, so there is no real case for the other one.
