#23 GR-Research NX-Bravo: $1540 kit with finished cabinets (assembly required) Gr-research eBay
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.
How it compares: Just above it: Wharfedale Super Linton - $1159 more, 3.4Hz higher bass extension (-3dB). Just below it: MoFi SourcePoint 10 - $1960 more, 3.4Hz higher bass extension (-3dB).
