How do you chose speakers based on room size?

What about an L shaped 12Wx19Lx8 ft ceilings with an ajoining dining room WP 7s 8s or could you sqeeze Maxx 2s in there? I do have 1 pair 16"x 48" tube traps to use.

Thanks, Halcro. There can be other reasons for the perceived tonal balance to change with level, but I think differing thermal compression characteristics among drivers is usually the main one.

Heykay, even though your 12 by 19 foot room would probably be considered "medium sized", the fact that it's open into another large room means that it's in effect a "large" room as far as the bass region goes. My opinion would be, either go with speakers "voiced" for a large room or consider using a sub with the intention of adding a little bit more energy across the bass region (rather than merely filling in below the main speakers, which is the more common usage for a sub). In many cases an opening into an adjoining room acts as a huge bass trap and can actually be beneficial, provided you can get the bass level up enough to offset the loss of bass energy.

Duke, That explains alot and makes a good case for a midrange driver that covers as much frequency range as possible.

I forgot to mention that I do have a Rel Studio III and I was using it with Sophia 1s which I just sold and was going to upgrade to the 7s or 8s but was curius about room size and Maxx 2s the height looks like it might be an issue with eight foot ceilings in room. And also on my rear right behind seating there is a long hallway that opens to bedrooms.

Duke ;

Like the others ...your explanation has cleared up a lot of things that I have noticed along the way ! Thank you .

What I was trying to get at concerning the 'guidelines' were things to look for that were specific to the size of room that the speakers are to be used in , not an all in one approach .
What design characteristics would be favorable for speakers in a small room that would not be favorable for speakers that were to be used in a large room and visa/versa ?

Thank you .
