Inclides two Amphion One18 powered by the Amp700 amplifier.

The Amphion One18 is a two-way passive high-resolution studio monitor designed to work as nearfield monitors in smaller rooms.

The Amphion One18 produces a superb balanced sound with high level midrange integration for a really detailed sound and superior clarity even at lower listening levels. The One18 like all speakers in Amphion’s professional range uses a low crossover frequency and high level driver to maintain an accurate phase response and imaging. In addition the One18 delivers a pleasing timbre with no unnatural sounds to create a natural and musical sounding monitor with no harshness. The passive radiator at the back of the unit allows for extended low frequency response.

Another benefit of Amphion’s natural balance and high level of midrange means that the monitoring doesn’t suffer from poorly designed monitoring setup as much as many other speakers and can serve as a consistent, predictable reference. This is truly useful for mastering engineers.

The Amphion Amp700 is a Class D stereo amplifier with a Class A buffer-stage capable of delivering enough power to all Amphion speaker models.


The Amphion Amp700 provides 2x350 Watts into 8 Ohms and 2x700 Watts into 4 Ohm with vanishingly low distortion and high resolution across the entire frequency spectrum. 


The Class A buffer stage not only allows for use with unbalanced and high impedance signals, but it also provides improved sonic performance adding a hint of Class A sonics to the Class D topology. The buffer is entirely built in-house and removes any possible DC offset from the signal and lowers the amplifier's input sensitivity.
