Placement for Soliloquy speakers

Mine are 3 feet from back wall, 6-7 feet apart with a 15 degree toe in or so in a 19 x 12 room with 9 foot ceiling for now ( moving this month). Carpet but some reflective surfaces with miniblinds and foyer tile floor ( small area). No complaints about the sound here. Sounds great.

How is this formula affected by lets open french doors in a study to a larger space or a door opening into a hallway. I am interested in your comments regarding lowest frequency that a room can accomodate. I hadn't consisdered that before but at the extremes at small and big it seems a quite apparent truism-- just not sure how an 11x 10 room with doors open versus an 11x 10 room with a door closed would vary with regards to calculation of lowest frequency would accomodate considerations...

Please teach me on this... I am all ears....

Fascinating. In a house, would a room's ability to handle bass as alluded to above be changed by whether a door was open or closed? Standard door.

If so better or less able?

I've got the point there are a zillion variables. This is just in a house with a room that can be enclosed but can also be quite open versus just moving speakers to a larger room. No problem experimenting a bit just wondering what you think.

How bout startin with a Yes or No to the first question for all of us simpletons out there.
