I would suggest you stick to the golden ratio room size to reduce the peak and nulls in a room. Sepmeyer's room size ratio is one of the best to follow. As per him, the best 3 room sizes are:
Room1 : Width = 1.14C and Length = 1.39C
Room2 : Width = 1.28C and Length = 1.54C
Room3 : Width = 1.60C and Length = 2.33C
*C = Height of the room
Assuming your room ht = 9' (recalculate accordingly)
The recommended sizes would be:
Room1 : Width = 10.26' Length = 12.51'
Room2 : Width = 11.52' Length = 13.86'
Room3 : Width = 14.4' Length = 20.97'
So your best option would be Room1 and if you want to retain the 21' length, the recommended width would be 14.4'.This calculation is based on an empty room. You need to consider the possible refelctive \ hard objects which will change the room dimensions (eg big almirah).
I would say 10x13 will be a very small room for HT. If you prefer the 10x13 room size, instead of a permanent brick wall, make a strong sliding false wall\doors at 13' (some thing like http://www.irepairhome.com/wp-content/uploads/2013/03/75-sliding-door-room-divider.jpg). This will help you in avoiding the windows in the 13' area and can use the 21' as a single space for normal use and for HT use, close the doors. If required, you can have the acoustics in these doors too.
In any room, seating location based on the 30:70 or 70:30 ratio rule will reduce the nulls and peaks (3.9' from the back wall wrt 13').
Also, if it is a dedicated HT room, avoid any windows (mainly to reduce the sound leaking). For better results, acoustic treatment is a must (atleast bass traps and first reflection absorption panels).
