Mapleshade's claims are/were based on the specific design of their cables (I have discussed this with Pierre @ Mapleshade).
To make use of longer lengths the cables can be ordered untwisted (@ least they could be 3 years ago) and in this application the (+/-) on each speaker is separated from one another along the length of the run by approx. 6". The left/right runs should also be separated from one another (6" - 8"). However, there was still a recommeded maximun length with this configuration.
Have not read any recent info @ their site, but when I looked into it the length guidelines pertained to "their" cables and were not a general rule of thumb.
I passed as I could not easily come up with a 24" wide channel in which to run the cables (my cables @ that time ran through wooden boxes installed in the sub floor).
