Is it plausible that dual JTR Cap 2400s with the extra 2k watts would bump me into distortion free listening that I like it regardless of my room challenges?
Here's my room again. It's small and the front corners are my only options.
Opening a door can have the effect of tuning the room somewhat, similar to what the port on a subwoofer does. So, it could cause you to have more SPL at a particular frequency, or for a relatively small range of frequencies, but I don't believe it would help to resolve the null at 50Hz.
I may have made this suggestion in an earlier post, but I think if you were willing to rearrange things a little, you could get one of your subs in the back left corner. That would give you a front right corner, and a back left corner, placement. That diagonal subwoofer placement can be effective in some cases.
What I would do is to move your equipment console, behind the sofa, as far toward the door as I could. You would have to rearrange things on the top of that console so that you could still access the light switches. Then, I would move the workstation as close to the console as possible, creating space for the PB16 in the back left corner. It will be tight, but just looking at your photos, it may be possible. I would exhaust that possibility before stacking the subs.
On the other hand, if that just won't work, or if you want to try stacking the subs anyway, I would just be sure to put something between them to avoid marring the finish. Trying the subs stacked in the right front corner may help to simulate what a single Cap 4000ULF would do in your room, so if the left rear corner really can't happen, that might be worth a try.
