The midrange is lightweight due to its moulded basket, still using the finest materials. The mounting depth of only ~1″ / 27 mm  and a cutout of 2.51″ / 63.8 mm enables fitment of this fullrange mid anywhere.


The new tweeter now has a machined housing with a mounting ring. Although the overall size of the tweeter is smaller compared to the v1, the audio response is first priority. From the tweeters resonance frequency of 1300 Hz & all the way up to 25000 Hz the audio graph average shows nearly no dips in audio response.

*It is essential that our speakers are given time to allow the suspension to soften up. Depending on use, this may take several weeks. While this process is undergoing, it is not recommended to apply full amplification power according to the speakers specs. Once the moving parts have been broken in, the performance of your speaker will increase.
