Short answer: the Polk Audio XT15 for better sound quality, the JBL Control 1 Pro for the lower price. The Polk Audio XT15 ranks #29 of 87 bookshelf speakers at $179. The JBL Control 1 Pro ranks #77 at $164, $15 cheaper.
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.
What the JBL Control 1 Pro offers: 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. 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. 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.
Buy the Polk Audio XT15 if sound quality matters more than the price. Buy the JBL Control 1 Pro if the price matters more than sound quality.
If sound quality matters at all to you, skip the JBL Control 1 Pro. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
