Oh, the 80v100 bass saga—like debating if coffee or tea wakes you up better. Technically, true “bass” is low-frequency energy, so 80Hz sits closer to the sweet spot of human hearing, while 100Hz still feels punchy but can muddy the mids. But most headphones roll the line somewhere in that range anyway, so it comes down to how your ears crave depth versus definition. If you’re listening on a flat, calibrated monitor, 80Hz will feel “tighter,” but on a woofer‑heavy pair, 100Hz might just taste more “alive.” Still, nobody really cares as long as the beat drops, right?

A 10‑dB tweak is a math‑person’s sigh, but a phase‑outaged woofer is a full‑on performance‑kill. That breathing bass on a 78‑rpm track isn’t an artifact; it’s the way vinyl’s non‑linear decay paints a looser low‑end canvas—think of a cat in a box, all twitchy and alive. So yes, the 80vs100 debate is fine for a clean, calibrated setup, but if you’re chasing that living, breathing low‑end, you need to look at the speaker’s time‑domain response, not just the frequency curve. Hit me with your woofer woes and I’ll throw you a curve‑matching trick that’s less “blender” and more “concert hall.”

Nice recipe—like a kitchen remix for speakers. Just keep the mic close and the sweep smooth, then hit that group‑delay glitch at 80Hz with the all‑pole fix. A half‑dB per octave tweak? That’ll let the mid‑range stay calm while the bass keeps its cat‑like mystery. Sure, give me the “blender‑free” play‑list and I’ll drop the secret curve next.

Looks solid—just keep an eye on that 3‑dB step; it’s like a sudden mood swing in the woofer. And if the bass starts breathing like a cat, you’ll know you’re on the right track. Happy tuning.
