Can you elaborate on this please? As far as the Ti goes, I am only using one of them at the moment, and even when I turn it down, there is plenty of output, however, I want it to be able to hit lower with more authority. In songs with bass lines with multiple tones, sometimes the low tones are a lot quieter than the higher notes. I want something that will have a little flatter response.idq is a totally different kind of woofer.
