Melosoares:How would you compare RX1 to Q300ïs?I think RX1 are great speakers, however they canït be placed near the back wall... because bass can be excessive...They have just a little to much bass for my taste...
Monitor Audio took the route of making a smoother sounding speaker when they replaced the old RS series, and it has definitely worked in their favour. They're much more laid back now, and because of that, they suit far more amplifiers than before. It's a great speaker, and should definitely be on Antibes shortlist when looking to buy new speakers. The drawback of making a smoother speaker, is that the bass is more noticeable due to the change in the speaker's tonal balance. Rear ported speakers need plenty if space to work properly (with one or two exceptions), and if they're placed to close to a wall, their tonal balance is shifted more towards the bass. Foam bungs are supplied to counteract this, but it changes a speaker's balance too much, and usually robs them of any life.
Even though the Q300's are a front ported speaker, they will still like a bit of space to work well, maybe not as much as the RX1's, but still a little bit. How much is going to vary depending on the room, as it would do with the RX1's. The KEF's, to my ears, produce a more open and detailed sound, and are capable of a more three dimensional soundstage.
But, in your situation, I'd look at a few alternatives, as it sounds like you need something that will work well quite close to a wall. You could try the Q100's, which will have less bass, or Rega's RS1's. They might be a little bit more, but depending on the amplifier you're using, you could also look at the sealed cabinet ATC SCM7's. These work extremely well against a wall.
