The bass extension is impressive for such a relatively small floorstander. MartinLogan claims to deliver a frequency response down to 46Hz, but this seems comfortably bettered in my room. It integrates well with the rest of the frequency range and ensures that the deep electronic notes of Beck’s Uneventful Days are something you feel as much as hear and there is a reasonable level of control and definition as well. This is undoubtedly helped by careful speaker placement in my room and positioning the Motion 20i closer to a rear wall reduces this coherence somewhat. It’s never going to be described as an urgent-sounding loudspeaker, but equally it doesn’t sound particularly languid or slow.

REVIEW: The Sonus faber Sonetto V Speakers

To be fair to the Sonettos, I left the past behind, making my way back to the current day, musically speaking. Bottom line, there was nothing I threw at the Sonettos that I felt they couldn’t do justice too. Getting in a party mood with “Oppa is Just My Style,” the Sonettos prove they can play loud when the need arises. Even at eviction notice levels, these speakers did not distort, bottom the woofer cones, or exhibit soundstage collapse. Staying at party SPLs, the deep bass line in Girls Day’s “Look at Me” had a few people looking for the subwoofer. And just before you think I’ve gone way too KPop on you, the new AC/DC single “Shot in the Dark” was just released, so a final infusion of heavy guitars (at high volume, of course) ticks the last box. This is a great pair of speakers that can play whatever you enjoy without excuse.

About the fine-tuning. As with other Wilson speakers, a step in the setup of the XVXes is measurement of the listening position, both in distance from the speakers as well as the floor. This is done to determine the correct settings for the various modules, in order to achieve exact time alignment at the listening position. But there’s also an important procedure that tailors the speakers to the amplifier with which they will be used. While previous Wilson models other than the WAMM used predetermined steps for time alignment of the drivers, the Gantry and Micrometer of the XVX allow infinite small incremental adjustments to correct not just for listening position but also the unique time smear of the partnering amplifier. Wilson Audio determines this through measurement of the amplifier, and those data are provided to the person setting up the speakers. Daryl Wilson admits that there are some similarities among the amplifiers he has measured, especially ones with similar topologies, but, as he put it, “Every manufacturer has its secret sauce.”
