This page lists all 4 GR-Research speakers ranked on this site across passive speakers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.
Large Size Bookshelf Speakers
Ranked #4 of 84 in Large Size Bookshelf Speakers - GR-Research NX-Studio: $3630 Gr-research
Pros: Ultra clean burst decay/waterfall plot. Amazingly open sounding due to the semi open baffle Neo3 ribbon tweeter, will image better than any other bookshelf speaker. Neo3 ribbon tweeter is one of the best ribbons around for detail. Bass will be very tight and fast due to the sealed enclosure, but may possibly need a sub.
Cons: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.

Ranked #20 of 84 in Large Size Bookshelf Speakers - GR-Research NX-Bravo: $1540 kit with finished cabinets (assembly required) Gr-research
Pros: Vertical dispersion is unusually wide for a two-way bookshelf: tonal matching holds from about 50° above the tweeter axis down to 20° below it, well beyond the roughly ±10-20° typical of most two-ways. Horizontal dispersion is also wide at about ±70° through the midrange, widening further when toed out, so sidewall acoustic treatment isn’t really necessary. Burst decay is extremely clean with essentially no ringing - the reviewer compared it favorably to a $13,000/pair speaker that showed significant ringing at 120Hz and 500Hz. A deliberate dip around 7kHz reduces sibilance while the 1-4kHz upper-midrange stays neutral, so the sound doesn’t come across as laid-back or recessed. Easy to drive electrically, with a 5-ohm minimum impedance and 2.5-ohm minimum EPDR. Available from $700 as a kit up to about $2,500 fully finished, with the option of the designer’s flush-mount tube/banana-plug terminals for a cleaner look.
Cons: Pointed straight on-axis there’s a deliberate ~5dB high-frequency bump meant to compensate for narrowing dispersion off-axis; it needs about 15° of toe-out (aimed to cross behind the listener) to sound balanced, which won’t suit every room layout. Higher-than-normal high-frequency distortion becomes audible in sine-sweep testing at higher output, and multitone distortion crosses the reviewer’s 3% threshold around 96dB, making roughly 88dB the safer output ceiling. SPL-limited by the manufacturer’s own admission - not intended for loud, full-range playback and best paired with a subwoofer, as with most two-way bookshelf designs. F3 of 77Hz and F10 of 45Hz mean bass only reaches about 50-60Hz in-room. A minor enclosure or port resonance shows up in the frequency response (though not in burst decay), likely a non-issue but visible in measurements. Adding a subwoofer reduces midrange distortion but doesn’t address the elevated high-frequency distortion.

Ranked #53 of 84 in Large Size Bookshelf Speakers - GR-Research X-LS Encore: $1300 Gr-research
Pros: An amazing value, especially if you managed to snag one of these built by AV123 in the early 2000s for $200-300. CEA2034 spinorama shows a generally flat on-axis response, especially in the listening window. Predicted in-room response is generally smooth and on-target. Distortion at 86dB SPL/1m is pretty clean above 200Hz.
Cons: A slight depression in the upper bass and some peaking in the lower bass shows up on-axis, along with directivity error in the crossover region. Vertical directivity requires staying within about 20 degrees of the tweeter axis. At 96dB SPL/1m distortion becomes “rather unhappy,” with bass distortion, a possible woofer issue around 2kHz, and a tweeter problem above 7kHz. As a DIY kit, it requires building the cabinet and crossover yourself.

Large Size Floorstanding Speakers
Ranked #1 of 54 in Large Size Floorstanding Speakers - GR-Research NX-Treme: $9662 for the kit with subs (assembly required) Gr-research
Pros: Amazing in terms of soundstage and imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. One of the highest sensitivity speakers around. Open baffle mids, highs and bass (using GR-Research Open baffle subs). If you have not heard open baffle bass, you must hear it in person, there’s no going back. Amazing in terms of imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. Can easily be driven by tube amps due to the mild impedance.
Cons: Very tall and will require GR-Research open baffle subwoofers one on each side
