Two good, well positioned subs and some PEQ are sufficient to achieve that. To achieve Geddes' goal involves more subs, more effort, and a different set of challenges & compromises than what I've had to deal with.
You said "If I wasn't thinkin' of something I'd be bored to tears". I think optimizing your HT using the Geddes method should keep your mind occupied for quite some time...
Well said. My approach is not really Geddes, but maybe a Geddes/Welti hybrid. I share his goal of excellent uniform FR across my seating positions, but I want headroom and extension as well.
What I really want is a Welti/Harman approach, but I'm currently stuck with disparate subs that makes their approach, well....complicated.
At this point I've measured and have a consistent full range FR response up to 105 dB.
I have sufficient sub headroom to at least 115 dB, but the disparate subs start causing some anomalies above the HPF.
So until I get me a couple more JTR subs or build some equivalent DIY, I think I'm as good as I'm going to get, but I do want more bass headroom than I have now, that's for sure.
The "if I wasn't thinking of something" comment was a bit facetious. I'll be glad to be done with it and just enjoy for a while.
I do still wonder about that 48 dB HPF though...
