A couple more things that might be helpful to you in addition to the GiK videos and the podcast:
1) give GiK a phone call and just chat with them. They're extremely friendly, knowledgeable and helpful over there. You can send them photos and diagrams, and they can make recommendations and explain the reasoning to you.
2) take advantage of Auralex' Room Analysis services. If you have a measurement microphone or even just an SPL Meter, you can pay for the "Room Analysis Plus" service, where you play a specific test tone file that Auralex sends you, and you record the results and send it back to them for analysis. That one costs money, but they also have a FREE service where you simply fill out forms and provide diagrams and photos. With that, they can provide general advice and guidelines. And it's free, so why not, right?
Really glad to hear that the replacement J25B is working properly! I hate it when a product I've recommended screws up. Makes me look like a chump

But at least APC came through for you. They're a solid company. But it never looks good when a faulty product gets sold. Never-the-less, I think you'll really appreciate having the battery backup in your system now. First power outage while a DVR recording is running? It'll all be worth it
