Nothing is so good that it can’t be improved! E170 has gone through a second face lift. Most noticable is the new taylored aluminum chassis. Then we added a new rim, spider, and a new stronger glue. This gave us a design that can take a lot of ”abuse” with a more linear behaviour. E170 goes even deeper (24Hz) and extends up to around 15Khz, making it a very wide range bass unit which can be easily combined with a number of tweeters in a 2-way system. In combination with our new E60, you get numerous crossover options from 120 to 2,5Khz. Why not try a linear array of 4, 9 or even 16x E60 units for example? We kept the dual coil and made Qt lower (0.437 in 8Ohm). For the advanced designer, the dual coil gives a number of options, firstly by connecting the two coils in single, series or parallel mode (16,32 or 8 Ohm), but then also when connecting multiple drivers from 2 to endless linear arrays. By shorting one coil with a resistor for example, you can get even more options, controlling the Q. (Qts will come down to almost half by simply shortening the second coil). E170 now comes with individual parameters included in each box!
