Excellent bookshelf speaker with lots of depth. Paired with the NAD C338 integrated amp also for sale. Type: two-way reflex loaded standmount loudspeaker Crossover frequency: 1.6kHz Drive units: Bass: 5.25 in aluminium cone woofer Tweeter: 25.4mm titanium dome Nominal frequency response: +/ -6dB 45 – 25,000 Hz Nominal impedance: not specified Connectors: single-wire binding posts Sensitivity: 86dB Dimensions HxWxD: 316 x 160 x 265mm Weight: 7kg Extremely entertaining and providing extraordinary value-for-money, the Argon 1s are clearly a fantastic little speaker across many types of music and will give hours of enjoyment. In fact this is as good an implementation of metal-coned drive units as I’ve come across. Too many designers combine such drivers to create an up-front image which places performers unnaturally close to the listener or, sometimes uneasily, in their lap. If these are anything to go by, Amphion is a brand that needs to be better known because the sound is so entertaining, joyous to listen to. That they are easily driven and so unfussy when it comes to placement makes the Argon 1 just adorable and something of an audio bargain. They’ve been really fun to use and brought a smile to my face on track after track. The fact that they are hand-made in Finland is the icing on a very tasty cake.
