Short answer: the KEF LS50 Meta if sound quality matters most, the JBL Control 1 Pro if price matters most. The KEF LS50 Meta ranks #4 of 160 bookshelf speakers, rated 4.5/5, at $1,599. The JBL Control 1 Pro ranks #145, rated 2.0/5, at $240, $1,359 cheaper.
The KEF LS50 Meta is the more accurate, deeper-bass choice. Uni-Q concentric driver mounts a 1” vented aluminum dome tweeter at the center of a 5.25” aluminum cone woofer, rated 79Hz-20kHz+. Its measured preference score, a predictor of how neutral it sounds, is 5.74 against 2.87 for the JBL Control 1 Pro. Its bass reaches about 68Hz before falling 3dB, against 78Hz for the JBL Control 1 Pro. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
What the JBL Control 1 Pro does well: 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. Watch for: 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.
Buy the KEF LS50 Meta if sound quality is the priority over the price, or the JBL Control 1 Pro if the price is the priority over sound quality.

Older model: the KEF LS50 (ranked lower, rated 3.9/5).
Pros: Uni-Q concentric driver mounts a 1” vented aluminum dome tweeter at the center of a 5.25” aluminum cone woofer, rated 79Hz-20kHz+. Speaker-to-speaker matching measured tight at roughly 0.5dB deviation between the pair tested, versus 2-3dB seen on some other speakers: likely why imaging stayed so precise. Imaging stays tight and focused even toed out, unlike most coincident designs where toe-out typically diffuses the image, giving more of an oval-shaped soundstage than a hard rectangular boundary. Horizontal and vertical directivity both hold to about ±50° at the -6dB point, so tonality stays consistent across roughly a 100° listening cone. The extended bass shelf is deliberately tuned for near-wall/boundary placement rather than the usual “pull it 3 feet into the room” advice, playing lower without excess boominess when placed close to a wall. At its frequent sale price, well below list, called a no-brainer for a compact stand-mount speaker. Independent ASR Klippel measurements corroborate this: very good directivity with the on- and off-axis curves tracking closely, and a predicted in-room response the reviewer called “very close to ideal.”. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 83dB.
Cons: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass. A 2-3dB scoop around 2-4kHz shows up in both the listening window and sound power measurements, matching a subjectively noticed lack of attack and vocal clarity that the reviewer wanted to correct with about 2dB of EQ. An on-axis diffraction dip around 8kHz smooths out with about 15° of toe-out (typical for concentric designs, but still present at 0°). Distortion is elevated at low frequencies since the single 5.25” cone shares surface area with the tweeter housing, reducing effective radiating area; multitone distortion crosses the 3% threshold at 96dB/1m, making roughly 88dB or below the safer output ceiling. Moderate sensitivity (~83dB average) needed 2-3dB more amplifier gain than typical in testing. Adding a subwoofer at an 80Hz crossover only helps lower-midrange distortion, not the elevated distortion in the 1-2kHz and above-5kHz regions. ASR’s own Klippel testing found the same pattern in starker terms: THD is very good at 86dB SPL/1m but climbs past 100% in the bass at 96dB SPL/1m, confirming this is not a near-field speaker for high-output bass-heavy material. Cumulative spectral decay (waterfall) also shows a couple of resonances lingering in the 1-2kHz region.

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.
