amphion helium 410 loudspeakers
The smallest of the Helium series uses a 4.5" paper mid/bass driver and a 1" titanium HF unit.
Amphion loudspeakers are just at home in a larger rooms as they are smaller ones, avoiding high frequency reflection - the main cause of brightness - by utilising clever waveguide technology to give a far more even dispersion of higher frequencies.
amphion helium 510 loudspeakers
The Helium 510 uses the same 1" titanium HF unit as the Helium 410, but uses a larger 5.25" mid/bass driver.
This larger mid/bass driver allows the Helium 510 to reach just that little bit deeper, as well as improving midrange presence, for an even more believable performance than its smaller sibling.
amphion helium 520 loudspeakers
The two-way Helium 520 is a slimline floorstander, topping off the Helium range.
The Helium 520 adds a second 5.25" mid/bass driver, decreasing distortion and driver excursion, increasing output and sensitivity, and improving bass and midrange presence for a more authoritative experience.
