No loss, except needing a larger cabinet for 2 drivers, and the cost of 2 over one.

Gain:
-more vertical directivity lobing in a vertical MTM.
-same sensitivity as one driver.
-more power handling over one driver, including halved Xmax for each the pair at the same output.
-easier impedance for a lot more amps, and easier to keep system impedance stable.

If you can afford it- what's not to like?

Wolf

Imp is the issue here as a 2 ohm is hard to drive indeed .

So there is no dampening losses ??

Your Qes damping will change, but it really is not a bad thing as a whole.

'Speed' is not a real seaker parameter, and no it does not.
Qes is the amount of electrical damping in the driver.
As long as the Bl curve, Qts, and Mms are corresponding to a well controlled driver, it's of no concern.
