I have been having big problems since I upgraded to larger powered monitors with the Emotiva Stealth 6. Because of room size and configuration, I went from using the Stealth 6 for my rear surround speakers to a pair of the Airmotiv 4s and both of those were too big and overpowering. Guess what? I'm back to using a pair of Min 21 for surround.
I need some small speakers for surround. Main speakers are Monitor Audio BX5 towers and BK Gemini2 sub. I have owned Minx Minx10 as rear speakers, but they sound too thin. Did you lose lot of information when going to smaller rear speakers? I think it would be optimal to put all speakers to small/80hz as THX recommends. I could buy Min22 for rear, but they don`t go lower than 120hz? There is lot of talk that you can benefit from larger rear speakers that go under 80hz easily. Opionions guys please!

I would be using 4.1 setup (phantom center, as my sweet spot is center and the distance between speakers arent that much. It really works good. I have owned center speakers, but now feels i don`t need one anymore. Smaller apartment also..)
Sure best bet would be using same manifacturers speakers, but... Monitor audio Radius 45 vs Minx Min22 would be the case. Price wise almost the same.. But i like the BMR element.

If you like the BMR, why don't you use either the Aero 2 or the Aero 3? Or, get rid of the Monitor Audio's and do a complete Aero or Aeromax system.

My situation with using the Min 21 as surround duty is only a temporary thing. I plan on larger surrounds when I can find time to wall mount them because I have little room on the floor and it looks bad. I really don't think you should mix and match speaker brands / models but many people do and are happy.

Hi Mr_Hifi,

What are you using for your pre/pro/receiver for decoding of surround sound? Can it set separate crossover frequencies for the fronts and surrounds?

Since you don't have a center channel, the front left and front right will make a phantom center. Aka, the stereo trick. This is very dependent on the speaker setup, room, Main Listening Position (MLP) and how well the down mixing is on your pre/pro/receiver so that no information is lost.

Generally the surrounds have about 20% of the multi-channel soundtrack, but must be able to reproduce the full frequency bandwidth of 20Hz to 20kHz. Good panning from front to back of the sound field during action sequences are a good test of this. Modern pre/pro/receivers have excellent bass management that will ensure the 20Hz to 20kHz frequency band is reproduced on the surrounds, depending on how the Room Equalization (REQ) determined the F3 value in your room as well as what the speaker manufacturer recommends as it's F3 value.

Since most modern receivers have REQ to help address room issues. Which one do you use?

The reason your previous setup was sounding 'thin' could be due for a number of reasons. Basic question on speaker setup - is it as per post number 2,030?

If so, have you carried out the sub crawl test to determine a few good places for the sub in the room? Generally a number of good places indicate that more than one sub can go in the room and for the majority of people multiple subs are better than a single sub. Your room modes will can make 30dB to 40dB swings in the lower frequencies. A frequency sweep measurement between 15Hz to 300Hz will show this. Multiple subs will help smooth this out so that:
  1. you'll get a wider sweet spot;
  2. more headroom for your amp;
  3. minimize sub localization; and
  4. with the ability to have a higher crossover frequency.

What are your room dimensions? Front to back, side to side and floor to ceiling dimensions please.
