Hi,
Now I have been working with the TacT for app. 1½ year, I have some experiences on that product. It seems to me, that especially in the bas the improvement in sound is huge. Besides that it is also improving the general sound in terms of naturalness, coherens between bas, midrange and treble, and the general balance between left and right.
It may be right, that the target curve is not telling you the total truth. And so what? As long as you are able to change the sound temperature by just adjusting the target curve I dont see any problems. Do you really think the right system will actually have a totally flat frequency response? Probably not. Because the system is only performing, what you want to measure. Think of f.x. Mark Levinson, which excellent product do have an equalized bass, even that the frequency curve is very flat. The frequency response is unfortunately only the half truth. Or trying different cables. Different sound, but still the same frequency response. A lot of other things counts.
It is important to notice, that according to my experience it is essential, that the correction is based on the same propriety measurement system, not a external system. It is during the design of the measurement system necessary to select between several solutions, and to decide how to measure what we exactly are hearing, is very, very complicated. A lot of AES-papers can document that. And on this very point, the TacT system is indeed very good. Very good similarities between what is measured and how it will sound. From that point of view it is not important how the resulting target curve will look like. The TacT system is NOT a measurement system, but a sound system.
In short, I find the system very hard to live without, because it - to put simple - solves the interaction problems with my listening room, which I never had solved. It will not do a bad speaker perfect, as it requires a very good and expensive speaker to make it possible to registrate the full benefits. By the way the system is also working very well with dipolar speakers fx MartinLogan Prodigy.
