Or bragging rights fodder.
I'd hope folks would be proud of attempting such endeavors! I certainly encourage others to share their approaches so I can learn from them. Again, kinda why we're all here...
Many purists won't even use a subwoofer. A system going down only to 40Hz works for them.
It might work well for them, especially if they prefer vinyl. But limiting the frequency range doesn't make it *accurate*. The very statement that it's a personal choice implies that they can hear a difference, but they prefer their way over the other. I don't think you could call intentional coloration over accurate reproduction "purist", more like "intentionally crippled". Maybe "minimalist" at best, but less is rarely more in electronics or sound reproduction.
Regardless, it's folly to chase sub frequencies with mains speakers, because optimal placement for both duties very rarely coincides in real rooms.
My system mains spec down to 19Hz. Do I care? Not really, but if it trips your trigger, go for it.
I'm guessing since you're throwing out a "spec" and you don't really care, that you haven't done any testing (e.g., REW sweeps) to see what your mains actually do in your listening space? I know you know about room modes and nulls. I agree with you that manufacturers' low frequency specs are almost worthless, and only taking the effort to measure and integrate can deliver good results in the lower frequencies. I have an idea of what my mains should be capable of anechoicly, since I made design choices when I built them. That's nice on paper, but it's how they integrate in my room that matters. I don't care how low (At what *volume*? At what distortion? For how long?) my mains can go, as that will never be their job, so long as they crossover well with the subs.
Just stop trying so hard to convince everyone else. You system, your money, your goals.
Yes, yes, and... not really. If you want accuracy, you can't summarily throw away data because you don't want to reproduce it. A lot of us are proponents of sub-20Hz because we acknowledge its intentional existence, and we aim for the most accurate reproduction possible. If you don't like the sound, expense, or trouble of it, just don't call what you're doing "sound reproduction", "accurate", "hi-fi", or "science", because it's not.
