Think a decent mic is more important than an app.

I can get one if there is any recommendation. My Samsung has the classic mic/headphone jack so it should not be a hard burden.

Any idea which mic to get?

Your OEM system plays the woofers in stereo.

Yes, you are literally repeating exactly what I wrote when I corrected your incorrect first statement where you claimed that higher BL needed a larger enclosure. Not sure what your point was there, since we'd already established that you were wrong.

You misread - I said it increased damping. Higher electrical damping corresponds to a lower Qes number.

I would recommend individual calibrated Umik-1 USB microphone from Cross Spectrum. It is calibrated down to 10hz. I have compare both correction file from MiniDSP and Cross Spectrum and it's not even close especially for below 100hz. Another advantage you get both 0 degree and 90 degree calibration file.

I never said higher BL needed a larger enclosure.

Damping has nothing to do with this discussion.
If you want to learn something ask. If you want to argue I'm not going to waste my time.

You were quoted above. I guess there must be two Billfitz's, my apologies.

Wow, that's a generous offer, I'll keep that in mind. I work in engineering management for a large audio products manufacturer, and have been in the industry for nearly 30 years. The next time I need someone on my team who is confidently incorrect and highly sensitive to being corrected, I'll have HR reach out.

Good for you, newbie. I may have designed speakers for the company you work for. I've done so for better than 20 manufacturers since 1972.

pierrye, they are sold out until later April/May. I will order one as soon as they have it back in stock.

Meanwhile, I may try to do a comparative test with whatever I have in hand as soon as the weather warms up a bit.

That mic is pretty much the same as this:

It's also back-ordered, probably a C-19 thing.
