@navyachts The ML Balanced Force speakers are great, but they are even larger and more expensive. I think the KEFs will do the job, fit in better and cost about 1/2 as much. Warning, one sub is never a good solution. You are better off without any.
If you do a lot of listening from one listening position just keep the microphone at the listening position for all measurements. If you tend to listen more as background music then use the 5 locations as per instructions. Now, you have level controls for bass and midbass. Run the program then turn the midbass down just a little and the bass up as far as it will go. Then start decreasing the bass a little at a time until things sound right to you. I am not sure if this will work, but give it a try. It costs you nothing. A thing to remember is a balanced sound at lower levels with have too much bass and treble when you turn it up. I recommend balancing the system at the loudest levels you listen. When you turn it down the bass and treble will seem a little low unless you have a loudness control.
