5-10 inches is really close to the front wall. Not many speakers are designed for this; I doubt this is optimal placement for the Salks, for example. I used to have North Creeks in my main system, which are designed for this, and are lovely -- definitely worth researching. Audio notes go close to walls, but I understand the require corners, which is not always possible If the speakers are not designed for near wall, I'd be inclined to stay away -- crowding can have really unhappy effects on the sound.
Add in the "wide sweet spot" and you've a really limited search. My Montana EPS2s fare well on this (though you need to be a ways from the speakers), and can be placed surprisingly close to walls for big boxes (18"-30"), but come in a bit above your price point; you might consider others in the line -- there are often good used prices.
In the end, I'd be tempted to drop the "near wall" constraint; in a 12x18 room I'd think you'd be able to find a decor, or negotiate one with interested parties, that would allow placement a bit further into the room, and would leave you with a lot of nice options, new and used, at your price point).
Good luck,
John
