Short answer: the JBL HDI-3800 for better sound quality, the Dynaudio Emit 30 for the lower price. The JBL HDI-3800 ranks #7 of 68 floorstanding speakers at $5000. The Dynaudio Emit 30 ranks #53 at $1274.25, $3725.75 cheaper.
What the Dynaudio Emit 30 offers: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. The two woofers hand off at staggered crossover points (around 1kHz and 3.5kHz) rather than sharing one, which avoids the acoustic lobing a shared crossover point would cause between the tweeter and the lower woofer, and adds a few dB of sensitivity in the process. Genuinely deep bass for a speaker around this price - measured F3 near 44Hz and extends audibly down to about 40Hz in-room without much difficulty. Harmonic distortion measures clean and low at both 86dB and 96dB SPL/1m. Good CTA-2034 sound power and uniform directivity mean the speaker takes EQ correction well if a listener wants to dial in its one tonal weak point. Dynamic range and compression performance are strong overall, with only a minor, high-Q compression artifact tied to a cone-edge resonance that’s unlikely to be audible. Wide, consistent horizontal dispersion around ±70° with just a small ~10° narrowing between 1-3kHz, and a reasonably forgiving ±20° vertical window centered on the tweeter axis. Watch for: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven - sometimes soft, sometimes forward - depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result. A cone-edge surround resonance shows up around 1-1.3kHz in burst-decay measurements (a trait the reviewer has also seen on other Dynaudio models) and lines up with elevated multitone distortion across roughly 600Hz-1.5kHz. An enclosure resonance appears around 350Hz in the impedance curve. Placed too close to a rear wall, the dual ports make the bass noticeably boomy - pulling the speaker out is needed to keep the low end from overloading the room. Fully resolving the top-end inconsistency needs a modest EQ correction (roughly +2dB with a Q of about 1, centered 3-6kHz), so out-of-the-box tonal accuracy in that band isn’t quite class-leading despite otherwise strong measured performance.
What the JBL HDI-3800 offers: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Watch for: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate.
Buy the Dynaudio Emit 30 if the price matters more than sound quality. Buy the JBL HDI-3800 if sound quality matters more than the price.
If sound quality matters at all to you, skip the Dynaudio Emit 30. It ranks near the bottom of the 68 floorstanding speakers, so look higher up the list instead.
