In terms of output and ability to blend with your system in the space you have the W6 is probably your best bet. The Illusion won't have the output of the W6.I was interested in taking a look at the Audiofrog option, but it says this comes in a dual 2 ohm configuration which means it has to be either ran at 1 ohm or 4 ohm, and given my limited space and using a 5 channel amp I don't think it will be an option here. thanks
