List speakers thast can be put cloeto rear wall

Many folks out ther eI am sure would like to hear of speaker that can be used realtively close to the wall.How many time do we hear in reviews or from folks here in the forumn that 'Speaker really open up five ft. fro the rera wall"But this is very difficult and a WAF killer gripe.Any suggestions for those whoneed to live in a no dedicated room where LIVING needs to take place?
