Product Details

The Desire To Want MoreACS T1 Triple Driver IEM

The ACS Encore has been designed in conjunction with a well respected session musician and is designed  for those who like a full on sounding IEM with hard hitting bass, detailed mids and crystal clear highs with plenty of headroom. The ACS Encore features the new detachable Linum cable and socket system, comes in a range of new exciting transparent silicones and adds a beast of an IEM to our product range.


The ACS Encore has 5 drivers and a 3 way crossover. Each driver or pair of drivers has been configured using the crossover circuitry to handle the frequency ranges they are best suited to. There is a large dedicated bass driver which handles the sub frequencies and upper bass, the crossover for the ACS Encore gives you plenty of deep punchy bass without any hint of distortion or bloated sound. The pair of mid-range drivers handles the low –high midrange frequencies, working together to present vocals and acoustic in a way that really brings your music to life. The pair of tweeter drivers take care of the high frequency range, by sharing the load across two drivers there is more headroom for the hard to reproduce high frequencies. The pair delivers crystal clear highs and adds to the sound to give a wider soundstage.

Not All Cables Are Created Equally

ACS has been working with the Danish company Estron ® who have created the revolutionary Linum® cable series. After trialling these great new products we are excited to now be able to introduce the new Linum® detachable cable system to our Studio Series products. Weighing in at 2.7g and only 1.8mm in diameter the cable is near invisible when worn and with being so light adds to the overall listening experience, there is nothing worse than having a huge loop of stiff wire hanging above your ear or the sheer weight of a cable tugging on your ear lobes while listening to your favourite tracks.

What really sets the Linum® cable apart from the crowd is the way they are constructed, each cable is made up of 6 litz wire conductors of 7 individual strands. Each strand is silver plated copper with enamel coating ensuring no colouration of the sound and a reliable connection. As an added bonus unlike most of the cables other manufacturer’s use it will not corrode or change colour through the lifecycle of the cable.

The Linum® cables have a market leading pull strength of 60N. The incredible size to strength ratio comes from the aramid fibres which are woven in. The outer jacket is made from TPA which gives the cable a silky smooth feel and ensures there is no microphonics to be heard if the cable brushes against clothing or skin. Talking of skin the cable is even skin-friendly approved and UV stabilized, so it will not turn yellow if exposed to sunlight.
