The Two Speakers In Full
Dynaudio Emit 30: $1,274.25 per pair Amazon eBay
Pros: 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. Measured bass extension of 44Hz (-3dB).
Cons: 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.

Infinity Reference 253: $400 per pair used Discontinued eBay
Pros: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Really amazing value for the performance. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange. Vertical directivity requires staying at or below the tweeter axis for accurate tonal balance. Distortion at 96dB SPL/1m is broadly elevated above the reviewer’s audibility threshold across much of the midrange. Minimum impedance dips to 4.2 ohms. Discontinued.
