Room Equalization Technologies 101 – Part 2 Introduction In the last post introducing this topic we saw that virtually all AV receiver and sound processor manufacturers now include automated equalization or room correction in most of their products even those costing as little a $500.00. The good news is that […]

My Home Theater: The Acoustic Discoveries, Changes and Upgrades.
Let’s recap where I was at this point. Overall I was sort of pleased with the rooms performance, but definitely not thrilled, and several issues had to be resolved. There was too much HVAC air and it cooled the room far too fast. This was a result of installing an […]

My Home Theater: Initial Acoustic Tests, Design and Acoustic Treatments
Now we have seen how the room was built, let’s review my home theater initial acoustic tests, design and acoustic treatments. Once the shell was complete and the doors installed and sealed I decided to see how the isolation performed, and what the rooms decay characteristics were like in its […]

My Home Theater: Installing the doors, HVAC and electrical systems
  The next challenge for my home theater was installing the doors, HVAC and electrical systems. I mentioned in my second post in this series that any small holes or significant air leaks from either the inside or outside walls will significantly reduce its ability to reduce sound transmission. The […]

My Home Theater Room Construction Techniques
  This second post in my quest for audio nirvana presents my home theater room construction techniques, and the acoustic absorption materials selected for the room. I thought that it may be more interesting to see how the room was built before reviewing my thought process for its design. Introduction The […]
