High Qms bass driver

[Ap]

How much is too much, from my understanding hgih Qms driver have less mechanical damping resulting in high impedance at Fs.
They are also better at producing bass compared with low Qms drivers (better at midrange).
Is there any downside or negative to having a driver with a very high Qms, say plus 10? (Considering it is only to be used for bass duties)

I don't have much of an answer, but a long time ago I posted this thread, and got some answers. I'm not sure if there was a concensus

Hope it helps a little.

Qms affects impedance. It is perhaps important if your amplifier is impedance sensitive, as a rise in impedance would then cause a rise in response..

As far as transient response is concerned, Qts is the important factor, as damping is a combination of Qes and Qms. For all but a few drivers, Qes is by far the most dominant in determining Qts.

Turn off your amp, tap the woofer cone. Turn the amp on and tap the cone That's electrical damping at work.

The simple answer is Qms cannot be too high.

You only have to worry about it if you use current drive.
