The intensity curves of the new SUBPAC S2 and M2 are linear in response from 0 – 70% for maximum accuracy when writing and mixing making it an extremely accurate and effective tool for high end professionals. From 70% to 100% we have applied a logarithmic curve which rapidly increases the intensity in a non linear fashion allowing for an enhanced bass response for those looking for a less accurate but more bass heavy listening experience. In this way we have accommodated the requests of some of the most respected music producers in the world while at the same time respecting the wishes of the many music fans that have sent us positive feedback based on their experience with the previous SUBPAC S1 model. The 0-70% range and the 70%-100% ranges are both useful for professional use and casual music listening as they provide 2 different ways of feeling the music you love. Use them as both different modes of appreciating your music, but also as an A/B tool when used with reference material you know well. And of course please feel free to send us feedback to let us know your thoughts – after all the new SUBPAC models have been designed and created for you. Enjoy!← How do the S2 and M2 intensity curves work?
