The M60 does have a x-over on the woofer because we need to have the x-over point quite low to blend with the 5 1/4" mid-bass woofer. As much as possible we try to design woofers to have natural response characteristics that are an integral part of the overall system response. Beyond this we use x-over design to achieve the desired final result.
