Trying to finish off my 5.1. Have KEF Q300 L/R and Q600C. Viewing area is 13x15x8. Need to use in-ceiling for rear surrounds. Using the philosophy of not needing much out of the rear surrounds, and with a limited budget, I've looked through the Monoprice offerings, but the occasional terrible review scares me off (plus, a lot of the glowing 5 star reviews seem a tad too perfect and succinct, i.e. made-up by the marketing dept). Also, I can't really tell the difference between the different speakers or other manufacturer's speakers (besides price and wattage). Can anyone vouch for their in-ceilings? A specific model? Can anyone recommend other in-ceilings? Would like to get this wrapped up and installed! Thanks!
