Introduction
I begin my Hifi journal 2 years ago when I bought my Onkyo amp and a pair of Q5. My addition cycle up very quickly after I built my first DIY preamp and then a pair of OTL amp! One thing I aways wonder is why the same piece of equiptment sound so differnt from my house and my friends house! One thing that comes to me after some serious search on the internet is room acoustics!
Of course, one way of solving the problem is to use various absorbers but this will be an eye sore at home and my wife will certainly refuse! Then I come across Tact. It is a great little piece of equiptment and the one I am using is Tact 2.0s.
The setup is easy and I will not repeat it as you can probably find it elsewhere. Awhile later, after I have heard an active speaker system in a friend's place, I decided that active crossover is the way to go. Another extensive search in the internet shows that there are a few options. 1. A DIY active crossover with opamp 2.digital crossover system which correct the phase difference between drivers as well. I chose the second option and bought DEQX. This piece of equipment allows 3 output for a 3-way speaker. I do not use its "room correction" function as it is really not room correction!
So, so far so good! But it doesn't end here! Now I am building a 4-way system and DEQX cannot provide a 4 way output. So, another extensive search on the internet bought me here!
Now, I am planning to sell my Tact and DEQX and I use a Audio PC to set it up! Thanks to Uli, who is very kind to give me a starting point with BruteFIR and DRC.
I have also come across this site http://members.chello.at/nordbahnfredi/ with very useful information and tips.
