I am very close to get two rythmik FV15 HPs to replace my current rythmik F15 in my basement. I currently have the F15 next to the couch( left ) . The only other place where I can keep the second sub is "behind the left speaker". I keep hearing the the two subs are best placed on opposite sides of the room - like front right and rear left, front left and rear right.

Wondering if it is bad to have the subs one each on both front left and rear left? I can try it myself but trying to avoid doing the heavy lifting if there are any clear guidelines for the location of subs.

With some innovative thinking and sacrificing some real estate I could make some room to place the second sub "behind he right speaker" but Wondering if this is definitely a recommended location.

Thanks
