The only way to do effective room correction is with a calibrated mic. You can not guess what the room and speaker are going to do (too many variables) you have to measure it. What are you going to measure it with? A thermometer?
yyz illustrates the problem Tact had. The designer Radomir Bozovic aka Boz is the Russian PhD and the father of room correction could not understand how everyone could not think like he could and assumed his system was obvious and self explanatory. It was very expensive stuff so he decided to sell it directly to keep prices down. His instruction manual sucked and the little company got buried in phone calls and very unhappy customers who could not make things work. You had to sit down with the computer and trundle though things until you got yourself on the learning curve. Then the sailing was pretty smooth. If you ran into a brick wall you called Tact and spoke only to Boz. People want plug and play and the Tact units were anything but. But, if you put in the time and learned how altering target curves and delays would affect the sound you could make your system do amazing things. They were a tweaker's paradise.
Anyway the company went under and Boz disappeared. My guess is that he owed investors a lot of money. Lyngdorf was a partner initially. You can still see some of Boz's design in the Lyngdorf units. They are easier to use but not as near as sophisticated and flexible. My Tact 2.2X is still going strong and there is nothing on the market yet that I wish to trade it for the Trinnov is close but the bass management is not near as good as the Tact's. I can change high and low pass filters independently one Hz at a time on the fly from the listening position from 20 to 300 Hz, 1st to 10th order! How can you beat that?
