Ken,
nice to hear that you had the possibility to listen to DD15s and still settled for the Meridian
Sounds like it goes pretty low, too. If you find the time, the graph would be interesting to look at. Maybe it's not inside the -3dB threshold below 20Hz, but if it still has any punch to, say, 15Hz, that would be great, I for one am very interested in these new subs!
John, would you be able to post a graph, too, showing solely the subs in action (single and dual)? Would be very interesting to see, I've understood that your room should be pretty well treated, right?
As a related matter, does anyone know of any source showing how low passages do different movies and music albums have? I have been wondering for long time how low is actually necessary, if one aims for covering, say, 99% of the source material. 8/
Wbr, Tatu
