Ok, So now I am completely stumped. Mission tell me to set M7ds rears and M7c1 to large as not a problem. However, in passing, a mate states is that this is unwise as a large dynamic shift could damage the speakers. He advises set to small and get a sub. However, puzzled by this, I sought advice and Bob007 (fellow poster) told me that should not damage units as any frequency below the missions 'BOTTOM' limit (70hz) simpy will not be heard. ok?? Fine, so maybe best option is to set rears and centre to small and redirect LFE to fronts as presently do not have a sub (saving up). However, I am now at my wits end and want to cry as I am thinking the following - 1. If rears, even when set to large to not drop below 70hz then I might as well set to large and forget the rear bass. or 2. Set to small, cross over at 70hz (ish) and still not get the bass at rear, sent to fronts in the interim. or 3. Set to small, sell body to get sub, still set x/o to 70 hz (ish) and hopefully get it right at last. or 4. Sell the lot as really frustrating me at present and revert to religion and go cold turkey over home cinema bug. or 5. Revert to the original plan and by some 'all small' pascal units to punish myself for getting wound up about it all..!!! I know that the much vaunted advice here is listen, as only the owner of the gear in questioncan decide but I really need steering here as I cannot really tell much difference, although to the trained ear it probably will be noticable. I have come to realise that there are many M7ds owners here. Well, thats it. To paraphrase Princess leia, 'help me, you are my only hope' Thanks in advance, Captain Benefit.
