Short answer: the Dynaudio Emit 30, if you are buying new. The Infinity Primus 360 ranks higher than it (#77 vs #114 of 188 floorstanding speakers, 4.2/5 vs 3.9/5) but is discontinued, so only consider it used; the Dynaudio Emit 30 is still sold new at $1,274.25.
The Dynaudio Emit 30 is the deeper-bass pick. A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. Its bass reaches about 44Hz before falling 3dB, against 53Hz for the Infinity Primus 360. 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.
The Infinity Primus 360 is the more accurate option. Its measured preference score, a predictor of how neutral it sounds, is 4.97 against 3.84 for the Dynaudio Emit 30. The catch: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average.
Buy the Dynaudio Emit 30 new; the Infinity Primus 360 is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
Dynaudio Emit 30: $1,274.25 per pair Amazon eBay
Same family: the Dynaudio Emit 10 (smaller bookshelf, estimated 3.2/5), the Dynaudio Emit 20 (larger bookshelf, rated 3.6/5), the Dynaudio Emit 50 (larger floorstanding, ranked higher, estimated 4.2/5) and the Dynaudio Emit 25C (center, estimated 3.7/5).
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 Primus 360: $650 per pair Discontinued eBay
Same family: the Infinity Primus 150 (bookshelf, rated 3.4/5).
Pros: A three-way tower from 2005 (two 6.5” mid-woofers, a 4” mid-range, and a 0.75” dome tweeter, 8 ohms nominal) that holds up remarkably well by modern measurement standards: on-axis linearity is within about ±2dB, and the listening window stays consistent out to roughly ±30° horizontal and ±10° vertical off the mid-range axis. Horizontal directivity is well controlled out to about ±75° before tonality starts to drift, meaning the reflected sound in a room stays close in character to the direct sound: a speaker that takes EQ well without fighting itself. Harmonic distortion measures low at both 86dB and 96dB, and multitone distortion stays under the reviewer’s 3% threshold. Silky, smooth midrange with a rich lower-midrange/upper-bass character. No mechanical issues or surround degradation found in a 20-year-old pair, and a second unit measured within about 1-1.5dB of the first, suggesting good long-term consistency for the design. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average. Bass output drops off fairly quickly below about 50Hz in-room (F3 53Hz, F10 37Hz), so a subwoofer is needed for real low-end extension. Resonances show up around 170Hz, 220Hz, and 350Hz. On-axis, the lower treble can sound a bit bright or sibilant when the speaker is aimed directly at the listener; toeing out about 10-15° (rather than the more extreme 30°) gave the best balance, and some sidewall acoustic absorption further tamed a 4-5kHz peak. Placed close to the rear wall, bass gets boomy: pulling the speakers out about a foot resolves most of it, with roughly 1.5 feet from the wall as a good compromise between bass character and typical room aesthetics. Straying beyond about 25° above or below the mid-range axis introduces audible suckout. No longer in production, so it’s a used/secondhand purchase only.
