One of three standmounts in the Helium range, the 510 offers a combination of relatively conventional components implemented in a slightly unusual way. The 25mm titanium dome tweeter is set inside a deep waveguide that the Finnish maker says is key to the overall performance. By using such a waveguide, the claim is that the Helium510 produces a broad stereo image that is not confined to a single ‘sweet spot’.

This is partnered with a 130mm doped paper cone mid/bass driver, covered with a metal grille. The bass output is augmented by a fairly large circular reflex port at the rear. Unusually, the port is placed directly behind the driver and the terminal panel is located behind the tweeter towards the top of the cabinet. It looks a little unusual, but is said to improve the flow and integration between port and driver.

Amphion has a very distinctive design aesthetic, making the Helium510 one of the more striking cabinets here. The black waveguide and mid/bass driver grille cover break up the white of the cabinet effectively, while full white, black and walnut wood veneer options are also available and livelier grille colours can be had for £ per set.

Sound quality

The claimed sensitivity of 86dB into 8ohm feels a little pessimistic, but this should not be considered a tricky speaker to drive. It also largely succeeds in Amphion’s stated aim of avoiding a clear sweet spot. Almost

Lover is delivered in a spacious and even fashion that avoids sounding diffuse. The tonality is wholly convincing too, with vocals that are rich and smooth while the piano displays excellent decay. With the more upbeat Lose Yourself To Dance, the bass extension isn’t as deep as some designs here, but it is detailed, fast and superbly integrated with the rest of the frequency response.

This same liveliness sees the Amphion also work well with the rougher Doors recording. At all but the most firmly anti-social volumes, it manages to balance top-end sparkle with enough refinement to avoid

coming across as harsh, while its open and expansive presentation does a good job of helping to place fine detail in a convincing fashion – making the whole performance more believable.

The Amphion then finishes a strong showing in fine style with Synchrony.

The complex percussion and bass are given the space they need and the Helium510 handles the challenging time signature of the track with a confidence and assurance that some other speakers here can lack. Once again, the three dimensionality and space around the upper registers makes for a satisfying listen
