Really need some help with sub placement info, please see the attached photos for reference. If you look at my room diagram you can see that because of the 4 foot opening to the kitchen and family room I am dealing with a huge area 6500^3+ and then throw in WAF that wants the subs out of sight, plus there really isn't room to place one up front. I had ordered a set of Rythmik FV18 paper cone subs and after thinking about the fact the only location I have for placement is directly behind the sofa I canceled the order and here's why. I realized that only having a nearfield placement would be good for TR especially given the cu ft involved as the subs would be 2 inches from the back of the sofa. But I was informed by several members that having both FV18's behind the couch laying on their side practically touching, so as to not be seen thru the window behind(again WAF), that I would not be getting the help of having duals by placing them in opposite corners or at least a distance from each other. In effect I was just doing one big sub behind the couch at a cost of $3348. So I decided to cancel the 2 subs and go with a dual cabinet setup. Was going to go with the Rythmik FV25hp because of the extension but started researching around and saw the new TV3612 with its lower extension and of course its great midbass, laid on its side behind the sofa was going to be real tight because I only have 26" of space to the wall (again WAF). So I came up with the idea to take the mounting feet from the bottom and mount them on the front corners and make the first TV3612DF sub. I've been talking with Tom and he said its doable and was going to check this weekend about using the existing holes for the grille and mounting them there. But I know the guy is swamped with other projects so here is my question, finally. Looking at the picture could I stand the sub up in the left rear corner facing forward,backward or even sideways(open for suggestions) and still get all the TR I would get versus placing it behind the sofa. I should mention we are on a suspended wood floor which should help, but don't really have any other placement areas other than behind the sofa or left rear corner which you can see is right next to the sofa, sub would actually be slightly touching the rear corner of the sofa. I just ordered the TV3612 about an hour ago and told Tom not to bother trying to see if the feet will work in the grille hole spots, I can always get some 3" thick foam for the corners which was Toms plan B or I will tap the holes myself, but I'm really interested in seeing what members here think about just placing it in that rear corner spot. Really appreciate input from the members here, thanks in advance.
