Short answer: the Polk Audio XT15. It ranks #52 of 160 bookshelf speakers by sound quality, rated 3.7/5, at $149; the JBL Control 1 Pro ranks #145, rated 2.0/5, and costs $240, so there is little reason to consider the other one.
The Polk Audio XT15 is the more accurate pick. Very low $149/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. Its measured preference score, a predictor of how neutral it sounds, is 4.56 against 2.87 for the JBL Control 1 Pro. The tradeoff: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB).
The case for the JBL Control 1 Pro: 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. The catch: 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 Polk Audio XT15. It is rated higher for sound quality than the JBL Control 1 Pro and costs less, so only choose the other one for a particular feature it does better.

Polk Audio XT15: $149.00 per pair Amazon B&H Photo Video Crutchfield eBay
Same family: the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT60 (smaller floorstanding, rated 3.5/5), the Polk Audio XT70 (larger floorstanding, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5), the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5) and the Polk Audio Monitor XT12 (larger subwoofer, estimated 3.3/5).
Pros: Very low $149/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. Off axis sound tracks the on axis response reasonably consistently for the price. Measured bass extension of 77.6Hz (-3dB).
Cons: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB). On-axis response is relatively uneven, with an average deviation of about 0.45dB, and its listening window is less smooth than pricier speakers. 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.

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.
