Entreq Max T screws the Eartha cable connector to the back of the earthing box.
Max T is a significant evolution of Peak 4 and offers a significant performance improvement to both older and newer earthing boxes.
Max T also fits exceptionally well with Everest and Peak 4.
These 3 products are used to fine-tune their soil boxes. If you want to calm down the sound, you choose a K2. If you think the sound is too muffled, you choose an Everest. The Peak 4 with the new Tungsten mix gives more punch.
On the back of each soil box is a wooden screw. This can be replaced with for example Peak 4 which contains 5 different metals. These influence the properties of the earth box and not least Tungsten gives an expression of weight.
