This might work for people who listen quietly and/or with high WAF
It's just NOT
practical to put the required
amount of cones into LCR's.
I wanted to feel it in my chest, without a hint of distortion. That's the kind of fire power it takes.
I listen 15db above THX, so it took 16 PA-460's to keep up with my listening preference.
He mentioned in the video he listens at 15db below THX, which is 1000x less energetic (because db's aren't a linear scale system...)
For me it was never
about reducing the load on my LCR's, they are capable of handling 2hz to 30khz as-is, and that's exactly how I run them. (I just wanted more, LOTS more!
Mine are front corner-loaded, which helps boost the SPL and blend with the LCR's (my MBM's are time-aligned to the LCR's). Stealth deployment behind my fronts, you don't even notice they are there!
Would placing them behind me make them even louder and with less nulls? undoubtly...
I tried that with 4 of them and didn't like the sound of it nearfield. YMMV.
The middle of my room is a bit of a mid-bass blackhole, I had to use an overwhelming amount of force to get it resolved.
What I disagree with, is his test method. I'm not sure what his system has in it (probably just regular subs?), so it would have been much better to measure what was directly on the LFE track rather than his in-room response! Then we would know what is ACTUALLY on the disc.
<20hz is for earthquakes, pipe organs, BassILoveU, and such.
20-50hz is what I call "boomer bass", it's the meat and potatoes of the bass region (rap and dubstep, and other boomer styles of music).
50-300hz is what I'd call mid-bass which is where 99% of music and movie impacts are located.
In this region we are talking: dance/pop music, metal/rock, gun fire, explosions, drums and bass guitars, cellos, and jump surprise scares and chest-kick.
People vastly underestimate the amount of cone-area they need.
In 2009 I had 2 PA-460's, in 2012 4, and 2017 16.
I'm good now, that's more mid-bass than should be legal.
