Product Details

Born AgainACS T2 Triple Driver IEM

This is the redesign of the top selling ACS T1. We have
kept all of its best assets and then improved on the product. The ACS Evolve retains the reference quality and warm frequency response of the T1, if it isn’t broken why fix it? The ACS Evolve features the new detachable Linum cable and socket system, comes in a range of new & exciting transparent silicones and is the same price as its predecessor.


The ACS Evolve has 3 drivers and a 3 way crossover. Each driver has been configured using the crossover circuitry to handle the frequency range it is best suited to. There is a large dedicated bass driver which handles the sub frequencies and upper bass with ease resulting in a rich detailed bass response which is not bloated or muddy sounding. The mid-range driver handles the low–high midrange frequencies and presents vocals and acoustics accurately and beautifully without being overpowering or fatiguing. The tweeter driver takes care of the high frequency range, delivering crystal clear highs and giving a clarity and detail to your sound like never before.

Out With The Old, In With The New

We have completely done away with the detachable cable and connector system found in the T1 in favour of the Linum BaX cable and socket system.
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 life cycle 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 micro phonics 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.
