Short answer: the Klipsch RP-504C II. It ranks #35 of 98 center channel speakers by sound quality, rated 3.8/5, at $499.99; the Dynaudio Emit 25C ranks #46, rated 3.7/5, and costs $599.25, so there is little reason to consider the other one.
The case for the Klipsch RP-504C II: The largest Reference Premiere center puts four 5.25” Cerametallic woofers around a 1” titanium tweeter in a Tractrix horn, for a very high 96dB sensitivity. The catch: On-axis response is the least even of the Klipsch centers (1.13dB average deviation), and directivity varies strongly with frequency (4.27dB directivity index deviation), so the tone changes for off-center seats and in reflective rooms.
What the Dynaudio Emit 25C does well: 2.5-way crossover rolls off the outer woofer at 1kHz, reducing horizontal acoustic interference compared to standard 2-way MTMs. The catch: 4-ohm nominal impedance requires stable current delivery.
Buy the Klipsch RP-504C II. It is rated higher for sound quality than the Dynaudio Emit 25C and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Klipsch RP-504C II: $499.99 each Amazon eBay
Pros: The largest Reference Premiere center puts four 5.25” Cerametallic woofers around a 1” titanium tweeter in a Tractrix horn, for a very high 96dB sensitivity. Erin’s Audio Corner measured the deepest bass of the Klipsch centers here, 71.8Hz (-3dB) and about 43Hz (-10dB), and a preference score of 4.58 without a subwoofer. Measured bass extension of 71.8Hz (-3dB).
Cons: On-axis response is the least even of the Klipsch centers (1.13dB average deviation), and directivity varies strongly with frequency (4.27dB directivity index deviation), so the tone changes for off-center seats and in reflective rooms. It is 814mm wide and 383mm deep, so check shelf depth before buying.

Dynaudio Emit 25C: $599.25 Estimated Amazon eBay
Pros: 2.5-way crossover rolls off the outer woofer at 1kHz, reducing horizontal acoustic interference compared to standard 2-way MTMs. Cerotar 28mm soft dome tweeter with Hexis inner dome delivers smooth, uncolored high frequencies.
Cons: 4-ohm nominal impedance requires stable current delivery. Rear dual ports need breathing room if wall mounted. Rating estimated from Emit series testing.
