Polk T15 vs JBL Stage 250B

Short answer: the JBL Stage 250B on measured sound quality, the Polk T15 on price. The JBL Stage 250B ranks #32 of 87 bookshelf speakers at $439.95. The Polk T15 ranks #78 at $149, $290.95 cheaper.

What the Polk T15 offers: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Watch for: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”

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 T15 if the price matters more than sound quality. Buy the JBL Stage 250B if sound quality matters more than the price.

If sound quality matters at all to you, skip the Polk T15. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
