Short answer: the Polk Audio XT15. It ranks #29 of 87 bookshelf speakers by sound quality at $159.99; the JBL Stage 250B ranks #32 and costs $439.95, so there is little reason to consider the other one.
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 Stage 250B offers: Good local Spinorama scores of 3.29 raw and 5.83 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Watch for: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.
Buy the Polk Audio XT15. It ranks higher for sound quality than the JBL Stage 250B and costs less, so the other one has nothing left to offer.
