Short answer: the JBL L52 Classic for sound, the JBL Control 1 Pro for install duty, though neither ranks well in its class. The Control 1 Pro is built for wall-mount and installation work with magnetically shielded transducers, a rugged molded enclosure and SonicGuard overload protection, but its sound power and predicted in-room response are badly uneven next to a JBL 305P Mark II. The L52’s walnut veneer and Quadrex grille are the appeal, though its compression and distortion from about 1-5kHz were inconsistent. Both are rated below 3.0/5 among the 90 bookshelf speakers, so if sound quality matters, consider the Philharmonic Ceramic Mini instead, ranked #2 at $900.
Buy the JBL L52 Classic if sound quality matters more than the price. Buy the JBL Control 1 Pro if the price matters more than sound quality.

JBL L52 Classic: $999.00 per pair Amazon eBay
Pros: 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. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 85dB.
Cons: 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.

JBL Control 1 Pro: $240 per pair Parts Express eBay
Pros: Magnetically shielded transducers and a rugged molded enclosure make it a durable choice for wall-mount or install use, with SonicGuard overload protection built into the crossover. Feels solidly built despite the low price, and the professional crossover network uses steep slopes. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Sound power and predicted in-room response measurements are badly uneven compared to the JBL 305P Mark II tested alongside it, with no waveguide to control directivity as the woofer beams before handing off to the tweeter. The reviewer performed no distortion or dedicated listening test on this unit and concluded he didn’t “think there is a reason to purchase it” over a proper studio monitor at a similar price.
