I will send them a reminder email let's see what that brings. Apart from the problem; don't underestimate the "gain" you will have from adding a DSW. I have DSP7200SE (left, center and right) at the front which, i thought, should have enough "ump" to have a solid bass during mainly movies. But adding a DSW.2 (and later a 2nd DSW.2 to solve the isssue this thread is created for) makes a major difference, not only for movies using LFE channel but also for music. You're right about timing issues when mixing an analog sub into the mix. If you don't have a processor which is capable of handling that i wouldn't go that route..
On my setup with the trinnov Alt32 i was able to almost completely prevent the DSW.2 problem from happening. Only in some very complex movies (like oppenheimer) i hear the DSW's popping a bit. In music it never happens, even with very deep basslines. Does not alter the fact that i want to have this solved by Meridian as it is clearly a problem in the DSW family.
