Hey all, I've owned my HT for 2 or 3 years and have never calibrated the video or audio portion of it mainly because of how low end my equipment is (Sony HTiB with reciever sub and 5 speakers and a 20 inch Sony Tv)but with my current financial situation I don't see myself upgrading to higher end equipment any time soon and would instead like to possibly calibrate my system for the first time and see how much of an improvment that makes. A couple concerns I have though, given the low end equipment I mentioned above would I even be able to calibrate. In other words can a HTiB speaker and reciever combo even be calibrated? and what about my display, a 20 inch analog Sony Tv that is 5 years old and a far cry from the 36 inch HD Tvs of today, can my current display even be calibrated. Last, what do I need to buy to do all this, don't I need Avia and a SPL meter? Thanks.
