Short answer: the GR-Research NX-Treme for better sound quality, the JBL Studio 698 for the lower price. The GR-Research NX-Treme ranks #1 of 71 floorstanding speakers at $9662. The JBL Studio 698 ranks #21 at $599, $9063 cheaper.
What the JBL Studio 698 offers: High-Definition Imaging (HDI) horn waveguide paired with a 1” compression driver provides excellent high-frequency directivity control and seamless acoustic handoff to the 6” PolyPlas midrange. Dual 8” PolyPlas woofers deliver robust low-end authority with solid bass extension down to an F3 of 53Hz and F10 of 34Hz. High voltage sensitivity (90dB SPL at 2.83V/1m) and clean power handling provide effortless dynamic headroom and low distortion for home theater and music listening. Watch for: Measured response exhibits a prominent mid-bass emphasis bump around 80Hz that can sound overly thick or chesty in smaller rooms without DSP EQ. Treble response lacks top-octave ‘air’ above 12kHz compared to high-end dome or ribbon tweeters. Physically large, heavy cabinet (35.8 kg per speaker) requires careful room placement and a wide acoustic footprint.
What the GR-Research NX-Treme offers: 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. Watch for: Very tall and will require GR-Research open baffle subwoofers one on each side
Buy the JBL Studio 698 if the price matters more than sound quality. Buy the GR-Research NX-Treme if sound quality matters more than the price.
