Hi all I measured the room from my listening position with test tones and a SPL metre.

Using the main speakers only I get the following results using a 90db SPL setting :

30hz 0
40hz -3
50hz -6
60hz -2
70hz 1
80hz -1

I tried the sub in several position, in the front corner, alongside a speaker, but the position with by far the flattest result was on the side wall mid-point between the sofa and speakers.

30hz -1
40hz 0
50hz 1
60hz 2
70hz 2
80hz 3

So I wonder whether I should cross over a little higher maybe around 50 and lower the volume slightly. Once the sub is properly broken in (only 10 hours so far) I will do some critical listening tests.
