Short answer: the Q Acoustics 5040 if sound quality matters most, the Dynaudio Emit 30 if price matters most. The Q Acoustics 5040 ranks #113 of 228 floorstanding speakers, rated 4.1/5, at $3,998. The Dynaudio Emit 30 ranks #139, rated 3.9/5, at $1,274.25, $2,723.75 cheaper.
The case for the Q Acoustics 5040: Well-built floorstanding speakers that are easy to drive, playing loud on modest amplifiers with a smooth, well-integrated midrange. The tradeoff: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output.
The Dynaudio Emit 30 is the deeper-bass pick. A slim tower with surprisingly deep bass for its price, low distortion, and even sound that responds well to EQ. Its bass reaches about 44Hz before falling 3dB, against 70Hz for the Q Acoustics 5040. 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.
Buy the Q Acoustics 5040 if sound quality matters more than the price. Buy the Dynaudio Emit 30 if the price matters more than sound quality.

Measured Differences
- Tonal accuracy above the bass: with a subwoofer taking the low end, the Q Acoustics 5040 scores 6.4 against 5.7 for the Dynaudio Emit 30 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
