I’ve been working on how room acoustics alter the perceived sound of a speaker, and I suspect the impedance curve of the drivers might be masking some subtle resonances. Maybe we could compare notes on how the room’s modes interact with the speaker’s impedance profile?

Sounds like a good puzzle. If the speaker’s impedance dips at a room mode frequency, the driver will feel like it’s struggling, masking the room’s resonance. Try measuring the impedance while the speaker sits in the room, then overlay that curve with the room’s modal spectrum. Where they overlap, you’ll see the driver’s “masking” effect. Keep the speakers at a fixed distance from the walls and make sure you’re not standing too close—seat placement can throw off the numbers a lot. Then you can isolate whether it’s the driver’s impedance or the room that’s hiding those subtle peaks.

I’ll set up a sweep to capture the impedance in situ, then map it against the room’s modal peaks. That should let us see whether the driver’s low‑frequency dips are hiding the resonances or if the room itself is dampening them. I'll keep the speaker’s position fixed and maintain a consistent distance from the walls. We’ll compare the curves and isolate the culprit.

Nice plan, sounds solid. Just make sure you capture the full low‑frequency range—those dips are usually near 50‑80 Hz. And keep an eye on the crossover point, too. Once you have both curves, we’ll see if the impedance dips are masking room modes or if the room’s damping is doing the heavy lifting. Good luck!

Got it, I’ll make sure to include the 50‑80 Hz band and watch the crossover. I’ll keep the data clean and see what’s really hiding those room modes. Thanks for the guidance—let’s see which factor dominates.

Good luck—watch that low‑frequency band and keep the data tidy. If the impedance curve dips right where the room modes sit, it’s probably masking them; otherwise, the room’s damping will show the real culprit. Let me know what you find.
Gordon Gordon
Understood, I’ll monitor that 50‑80 Hz band closely, keep the data neat, and let you know once I see whether the impedance dips are masking the room modes or if the room’s damping is the real issue.

Sounds like a plan—just keep an eye on the 50‑80 Hz window and the crossover. Once you’ve got the curves, we can see if the impedance is swallowing the room modes or if the room is doing the dampening. Keep me posted.
