You, Sir, are one informed buyer. You have your preferences sorted.
Pls do audition the Lintons. Make sure you audition with all genres of music that you listen to. As mentioned earlier, because of the lower dynamic range, certain genres may not sound their best.
With just 12" of space behind the speakers, you might suffer a slight boominess and definitely, the soundstage depth would suffer. If you plan to have a TV in between, the centre imaging might not be as sharp either. There must be other side effects that may not be audible unless you have trained ears, and also, I cannot list them because I don't know enough!
If you do not want to take these risks, pls insist on a home audition or explore front-ported or sealed speakers. A close cousin would be Evo 4.4. They are, however, floor standards, and are more 'audiophile' in characteristics, something you may not like if you loved Linton sound. The boominess would get tamed but earlier mentioned issues with soundstage, imaging etc. might persist.
Tangential options could be to explore those speakers which thrive closer to the wall or are meant for near field listening. The former is an expensive proposition and the latter might not be suited for general living room listening, so forget you ever read this last part!
All the best, and do let us all know what you finally buy and your observations of the same.
