Short answer: the JBL Stage 250B. It ranks #52 of 88 bookshelf speakers by sound quality, rated 3.2/5, at $439.95; the MartinLogan Motion 4i ranks #62, rated 2.8/5, and costs $495.94, which makes this an easy call rather than a real tradeoff.
Why pick the JBL Stage 250B: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The catch: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
Why pick the MartinLogan Motion 4i: Best treated as a satellite: crossing it to a subwoofer lifts its predicted preference score from 2.73 to 6.36, so the shallow bass matters far less in a 2.1 or home-theater setup. The tradeoff: Bass-shy to the point of needing a subwoofer: the measured -3dB point is 159.7Hz, so on its own it produces almost nothing below roughly 160Hz.
Buy the JBL Stage 250B. It is rated higher for sound quality than the MartinLogan Motion 4i and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
JBL Stage 250B: $439.95 per pair Amazon JBL eBay
Older model: the JBL Stage A130 (ranked lower, rated 2.1/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 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. Measured bass extension of 64.5Hz (-3dB).
Cons: 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.

MartinLogan Motion 4i: $495.94 per pair Amazon Crutchfield eBay
Pros: Best treated as a satellite: crossing it to a subwoofer lifts its predicted preference score from 2.73 to 6.36, so the shallow bass matters far less in a 2.1 or home-theater setup. Directivity is the strong point, with sound-power deviation (NBD 0.426) lower than its on-axis figure (0.547), meaning the off-axis output tracks the front more evenly than most budget cabinets and the image stays stable around the room. The Folded Motion tweeter measures cleanly for the price, and 87.5dB measured sensitivity (2.83V/1m) means modest amplifiers drive it easily. Measured bass extension of 159.7Hz (-3dB), with a measured sensitivity of 87.5dB.
Cons: Bass-shy to the point of needing a subwoofer: the measured -3dB point is 159.7Hz, so on its own it produces almost nothing below roughly 160Hz. The balance is bright and uneven, deviating 2.7dB across 300Hz-5kHz with a clear upward tilt, and the review’s verdict is a “bass-shy, bright” speaker. A port resonance near 850Hz and high woofer distortion add audible roughness through the midrange, and impedance dips below 3 ohms, so it wants an amplifier comfortable with low-impedance loads.
