I never quite understood the shift. Reference level capability from 20-120hz with today's high excursion drivers and ridiculously inexpensive, high wattage amps is easy - like really really easy. But they don't just want to achieve it, their design goal is to vastly exceed it, using multiples to get them 140db+ capability in that range.
I don't get it. Who listens at 20db louder than reference?
Several of us, apparently. It's all about headroom, brah.
But seriously.... I'm not sure where you got the idea that there was a "shift" here at AVS to 20hz and up high SPL. Maybe you're thinking of the 'Marty' craze? Actually, in the past half decade, there has been a shift... to multi-sub systems, sealed. Drivers like your Ava18's and my RLp's (that were in the $350-450 range) and now available for half that price. Well...for the most part. 90% of the way, at the least. It isn't uncommon to see several AVS members with +8 18" sub systems. Dude, I went from dual RLp18 LLT's to fourteen
18's sealed in the exact same room.
I kinda.... had to. Also because it's fun.
But I needed to because I liked the SPL from my LLT's and wanted something at the very least similar if not better. Above 30hz I have ridiculous output, all of which I'll probably never use. But below 30hz....? Ehh. With fourteen 18's in my room.... it's just enough to be adequate to me. But I'm not normal.
Anyway... my point is that I don't agree that the trend has been high output above 20hz around here. If anything, people are chasing extension AND headroom at the same time.
