They are not as mid focused as the TIJF'S. Well broken in TIJF'S have more going on between 500hz to 1000hz.... without getting nasal. The Olintos, so far, have more going on between 1k and 2k.... just enough to add some more clarity than you get with lighter gaged DTF's. I prefer the sound of TIJF'S to the Olintos, but not the feel.... which is why my primary bass sports a set of Sadowsky Blue label flat.... all the mid focusb of TIJF's, but a touch stiffer. However, the Olintos thump aggressively (again, so far), which is a good sound to have in the arsenal.
