Subwoofer dropping off too early

Yep - woodern follor big windows leather sofas and little soft furnishings in the whole room. In my experience though I think this helps a little giving the bass frequences space and reflection to be able to develop (It is quite a large room) In my experience its small carpeted rooms with soft furnashings where sub woofer fail to bring across any kind of depth

Moved the Subwoofer again and cannot tell you what an improvment there is ! it is now clear that where the placment before was making the subwoofer boom at around 50hz and the lower frequencies were not able to develop. I have now moved the subwoofer to the centre right between the speakers and directly under my centre speaker (wall mounted) it looks a bit odd after years of the subwoofer being off central but its the sound that counts!

It's amazing the difference it makes isn't it.
