Short answer: the JBL Control 1 Pro, though neither ranks well in its class. It ranks #80 of 90 bookshelf speakers by sound quality, rated 2.0/5, at $240. The Polk T15 ranks #81, rated 1.9/5, at $149, $91 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Neumi BS5 ranks #22 at $139.99.
Buy the JBL Control 1 Pro. It is rated higher for sound quality, and the $91 saving on the Polk T15 is not enough to make up the difference.

The Two Speakers In Full
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.

Polk T15: $149.00 per pair Amazon eBay
Pros: 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. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: 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.”
