The Two Speakers In Full
Dynaudio Emit 20: $1,049.00 per pair Amazon eBay
Pros: Two-way design with a 28mm Esotar soft dome tweeter (Hexis-damped) and an 18cm mid-woofer, using a first-order crossover on the tweeter and second-order on the woofer. Exceptional bass extension for a bookshelf speaker: reaches a clean, authoritative 40Hz in-room, rare enough that the reviewer says most listeners could skip a subwoofer for typical music. Very low distortion across the board, staying below 1% THD down to 40Hz at 86dB and below 3% even at 96dB: unusually clean bass performance where most two-way bookshelf speakers start rising in distortion around 80Hz. Wide, remarkably consistent horizontal directivity (about ±50-60°) that holds steady up to roughly 13kHz: rare for a speaker in this format, thanks to a beveled tweeter edge that acts as a mild waveguide. Excellent compression and dynamic-range linearity at the frequency extremes, actually showing slight bass enhancement rather than the sharp low-end compression common in similarly-sized bookshelf speakers. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 83.5dB.
Cons: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact: confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it. A peak around 4kHz adds a sharp, edgy quality to some male vocals. A roughly 5dB boost above 10kHz gives cymbals and hi-hats excess shimmer that can sound unnatural, especially pointed directly on-axis. Vertical dispersion shows two separate crossover-related notches (above and below the tweeter reference line around 5kHz) rather than the usual single one, a direct consequence of the shallow crossover slopes used on both drivers. Multitone distortion is elevated in the midrange, possibly due to the woofer’s magnet structure lacking a shorting ring. Best aimed slightly off-axis (about 10-15° of toe-out) to tame the excess high-frequency shimmer, rather than pointed straight at the listener.

JBL Studio 630: $699 per pair Discontinued eBay
Pros: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many speakers start to beam and narrow. Good compression behavior: mid-bass stays taut and controlled from low to high volume without the sound falling apart or distorting as you turn it up. A pleasant, controlled mid-bass bump in the 60-100 Hz range adds punch to kick drums without bleeding into an uncontrolled boom on bass guitar. Horizontal radiation holds steady off-axis (about ±60°), so toe-in isn’t fussy. Compared directly to its predecessor, the JBL Studio 530, the reviewer would pick the 630 (smoother trend line through the upper mids and treble, and likely more dynamic headroom) as long as you’re willing to EQ. Measured bass extension of 54.2Hz (-3dB), with a measured sensitivity of 83.2dB.
Cons: Noticeable mid-range dip/scoop relative to the higher frequencies: not dramatic, but audibly “missing” something by the second or third track. Some tracks read as forward or aggressive around 2 kHz, like the upper frequencies are jumping out at you rather than sitting in stage depth. Needs EQ to bring the mid-range back up to be fully recommendable; without EQ available, the reviewer says he’d look at a different speaker entirely. Measured sensitivity (about 83.2dB) runs noticeably below the 85dB manufacturer spec, likely a byproduct of the mid-range dip skewing the average downward. Discontinued and no longer sold new.
