Short answer: the JBL Stage A120 for better sound quality, the JBL Control 1 Pro for the lower price. The JBL Stage A120 ranks #36 of 56 bookshelf speakers at $299. The JBL Control 1 Pro ranks #46 at $164, $135 cheaper.
What the JBL Stage A120 gets right: Comes with a port bung, letting you experiment between ported and sealed configurations - the reviewer found the sound improved somewhat with the port sealed. The catch: A pronounced “Batman”-shaped frequency response: boosted bass, a scooped midrange, and elevated treble (about 3-4dB above the midrange), driven partly by confirmed cabinet panel resonance around 800Hz-1.7kHz.
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. Watch for: Sound power and predicted in-room response measurements are badly uneven compared to the JBL 305P Mark II tested alongside it.
Buy the JBL Stage A120 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 56 bookshelf speakers, so look higher up the list instead.

The Two Speakers In Full
JBL Stage A120: $299 Discontinued
Pros: Comes with a port bung, letting you experiment between ported and sealed configurations - the reviewer found the sound improved somewhat with the port sealed. Distortion at 96dB is broadly comparable to competitors in this price range outside of some elevated low-end THD. Wide horizontal radiation pattern for a compact bookshelf speaker in the low-to-midrange.
Cons: A pronounced “Batman”-shaped frequency response: boosted bass, a scooped midrange, and elevated treble (about 3-4dB above the midrange), driven partly by confirmed cabinet panel resonance around 800Hz-1.7kHz. Directivity shows significant back-to-back peaks and dips, making the speaker harder to correct with EQ since the off-axis sound doesn’t track the direct sound cleanly. Elevated treble that some might call “detailed” reads as an unwelcome boost to the reviewer rather than genuine resolution. Compression testing shows the low end degrading substantially at high output (102dB). Overall considered one of the weaker speakers the reviewer has tested in this class, with a competing model (Emotiva Airmotiv B1+) recommended instead at a similar price. Discontinued.

JBL Control 1 Pro: $164 Parts Express
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.
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.
