Short answer: the JBL Studio 698 for better sound quality, the ELAC DF63 for the lower price. The JBL Studio 698 ranks #18 of 59 floorstanding speakers at $699. The ELAC DF63 ranks #29 at $649, $50 cheaper.
What the JBL Studio 698 gets right: 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. Set against that: Measured response exhibits a prominent mid-bass emphasis bump around 80Hz that can sound overly thick or chesty in smaller rooms without DSP EQ.
What the ELAC DF63 offers: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The tradeoff: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
Buy the JBL Studio 698 if sound quality matters more than the price. Buy the ELAC DF63 if the price matters more than sound quality.

JBL Studio 698: $699.00 Amazon Crutchfield
Pros: 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.
Cons: 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.

ELAC DF63: $649.00 Amazon
Pros: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The dedicated midrange driver keeps distortion low even at higher output, avoiding the intermodulation grain typical of two-way bookshelf designs. The waveguide keeps high-frequency directivity well controlled, and overall horizontal directivity is good up to about 2kHz. Harmonic distortion looks good at both 86dB and 96dB, and multitone distortion stays below the reviewer’s 3% threshold. A shallow bass rolloff (F3 71Hz, F10 29Hz) lets it extend fairly low without a hard cutoff. Preferred by the reviewer over the similarly-priced Polk R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk R700 as well.
Cons: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals. A mild peak around 10kHz makes shakers and similar high-frequency percussion jump too far forward in the mix; needed about 2dB of EQ to tame in testing. A dip in the 1-3kHz range gives the speaker a warm, slightly veiled character - the reviewer suspects the tweeter crossover point (around 2-3kHz) is set a bit high and could be lowered to fill this in. Directivity shows a noticeable handoff mismatch around 2.5kHz where the midrange driver hands off to the tweeter, though it’s minor at the -6dB point. Vertical directivity is narrower than horizontal, so listeners need to stay close to the tweeter axis. Low EPDR (about 1.5 ohms minimum) means a Class AB amplifier should be well-ventilated. Best positioned pointed directly at the listener and closer to the front wall - toeing it out into the room causes too much high-frequency rolloff.
