Bookshelf speakers close to rear wall... Bass issue

Yes there could be a bass issue but which it - too much or too little? And which design are your speakers - front or rear ported or sealed box?

I'm assuming standard issue. Speakers close to wall cause excessive/booming bass. Forum prescribes sealed box design to remedy the complaint, or at least try front ported speakers.

If the thread progresses we may even discuss plugging the port with the supplied bungs, or improvising with socks or something else to regulate the bass.
