speakers close to the back wall ?

My Focal 836v speakers sound great to me up against the wall. I like the increase in bass compared to what I heard in the store well away from the walls. The soundstage isn't quite the same, but I'm fairly locked in with possible locations. Mine are about a CD length from the wall so much closer than yours. I can't imagine anyone complaining about the bass in their current location. One is near a corner. The front and bottom ports seem to work well. Ironically, they are $3,000 retail price so almost exactly right.

That Salk Songtowers have a transmission line design, which allows them to be placed 1 foot from a wall with no boomy bass. For less than $3k you can get your own custom wood veneer and upgrade to the RAAL ribbon tweeter.

Go to North Creek Music and check out the Big Kat floorstanders. These and the mini-monitor Kitty Kat are the only remaining models in George Short's "near wall specific" series and are at the top of the line.

George has considered all the design factors that compromise a speaker's performance when it's placed near the wall and dealt with each one of them. With this placement, you won't get a better soundstage than the Kitties deliver and there is no boom. George's work with crossovers is outstanding. I'm gonna sound like a shill if I go on. Do check them out.

Audio Note speakers work well near walls and corners ... also transmission line Jordan jx92 based speakers from Carolina Audio, Konus Audio and AudioWood among others would work well also
