    My HT room is about 7x11x25 I have one small opening in the back of the room about 4 feet wide that leads into a hallway would this opening effect my room gain.

    Any opening affects the way your system sounds. The area beyond the opening is simply more space to "fill" with sound, requiring higher volume settings and consequently additional amplifier power.
    In most cases this is not a big deal for the main channels (as most receivers have ample power for average sized rooms at less than ear-bleeding SPL levels), but the most critical and affected area is the sub region. Openings have an effect on room modes (for better or worse). Filling the additional space will require a larger, more powerful sub (read expensive) than would otherwise be needed, because the larger a listening area is, the more difficult it is to achieve the lowest frequencies, espcially at high SPL levels.
    Hope this helps.
