@g11657 - here's an example....
My previous listening room was 15 x 12 x 8(high)
My speakers are floor standers with a LARGE rear port
I also opted for the 1/3rd 1/5th or 1/7th rule, but at certain low frequencies the bass was very "boomy" and resonated with something in the room - probably the walls.
Some tracks had an extremely bloated bass, whilst most other tracks sounded OK
I've since moved to a new house and the listening room is much bigger 40 x 16 x 7.5 - so I now have approx 8ft behind my speakers (1/5th)
That bloated bass is no longer a problem and the music is sounding extremely detailed and rich
Low frequency standing waves of this nature are extremely difficult to deal with - I had placed baffles inside the port, which made the effect less noticeable, but it was still there on a couple of albums.
You might find, like I did, a partial solution, but a complete solution can cost a lot and detract from the room aesthetics
You migt find a front vented port is better, but low frequency standing waves are difficult to remedy
Regards....
