Speaker Shootout (Left to Right):
1| Ascend Acoustics Sierra-2EX
+Clean bass & treble, biggest sound, best sub-bass, the attack and decay are astounding but not always noticeable
-Vocals lack presence, needs good positioning
*Currently using MiniDSP SHD with Dirac. These speakers sounded amazing at first but I found myself constantly changing the volume. I was struggling to hear the vocals at times and when I did increase the volume, the bass was overpowering. After EQ-ing, these speakers were by far the best of the bunch as I never found myself nitpicking about it and it just disappeared into the background. It could play loud enough for movies, and I never found myself needing a sub. During the shootout, it got two votes for the best speaker of the bunch. One person found it didn't sound "high-end."
2| Focal Aria 906
+Natural vocals, best mids, driver integration is seamless, best build
-Treble can get slightly sharp, bass has punch but no sub-bass rumble
*During the shootout, this was the best sounding for music right out of the box. Vocals on it was noticeably clearer than the others. However on some music there is a slight harshness or sibilance and detracted from the music. The lack of bass is not as noticeable on music, but for movies the lack of rumble on the sub-bass made explosions unrealistic. During the shootout, it got one vote for the best speaker of the bunch. One person found the harshness/sibilance annoying.
3| KEF Q150
+Point source imaging, easy to position, best when used near-field
-Doesn't play very loud, doesn't have out of room sound when spaced far apart (sounds the smallest), bass gets distorted easily
*During the shootout, this was instantly deemed the least impressive of the bunch. They sounded small, due to being spaced far apart. Also when level matched, this speaker struggled to play at moderate volume levels as we could hear the driver rattle. However, I have since moved them to a small desk to be used just beside my laptop and they sound phenomenal. When listening near-field, the center image and the bass appeared - they now sounded bigger than the box.
4| ELAC Uni-Fi UB5
+Warm sound, best center image, big sound
-Upper treble tapers off, can hear high frequencies distort compared to other speakers
*During the shootout, all three of us really enjoyed this speaker although it was lacking the "high-end" sound. It sounded big, fun and enjoyable. I suspect we just enjoyed hearing a speaker that's more noticeably warm compared to the others. Listening to some tracks however, we found that we couldn't hear the triangle instrument properly and it lacks sparkle.
Gear used: PC (FLAC) -> SMSL SU-8v2 -> Hattor Audio Mini Preamp -> Audiophonics Hypex NC252MP (MPA-252NC XLR) -> Speakers
Test conditions: Untreated bedroom, no stands but head level, no subwoofer, listen at 82dB max SPL@5m, measured 91dB max SPL@1m
I ordered an Asipilin LS3/5a (15 ohm) but it did not arrive in time for the shootout.
Bonus Round| Devialet Phantom Silver (Mono)
+Plays extremely loud, can fill a whole room with sound, plays well off-axis
-Frustrating UI, can't use own DAC/Amp, stereo setup issues
*This isn't part of the shootout as it's located in the living room but we listened to it on the same day. The Devialet sounds huge for such a small unit. The ample amount of sub-bass is the most noticeable compared to the speakers above. We could sit anywhere and be happy to have music played without distortion. After extended listening, the bass gets tiring and I'm considering using the MiniDSP SHD here as the Phantom only has an Optical In connection. Also note that I do not recommend using these on a stereo setup.
