The basic rule is the flatter the response the better, or better yet the flatter the response in the most possible directions the better. This being said the design goal behind the M80 is to maintain the flat response of all of our speaker models while increasing the overall achievable SPL without distortion. Turning up the volume will achieve this goal up to the point where you reach the maximum SPL attainable by the loudspeaker without distortion. This threshold is raised in the M80 design. Since the roll off in the M80s is not as steep as in the M40s the actual bass performance you will hear in your room will appear deeper with the M80s.

Agreed, the end design goal is paramount but if this can be achieved completely through driver design then a minimal x-over can be used. If the end design goal cannot be achieved completely through driver design then the use of x-over design to force the drivers to the end goal should be also employed. The M3 uses a high pass x-over on the tweeter. The exceptional performance of the M3 is achieved through the design goals themselves and it was possible to achieve these goals through the driver design with minimal x-over components in this model.

I get started at some fairly ridiculous hours of the morning; some claim it is still part of the evening before.
