Ok yeh that dip on the HP5's 100 to 200hz drop off how to cure it . had them on way and now on stands . IS it playing with movement ?

but, here is the real question sub/s I have a SVS2000Pro and if I move my head about 18" forward and 12 inches higher it is perfect.
but I cannot move closer to tv and build a platform 12 inch to put chair on.

Is this also a matter of subwooofer crawling ? right now it is front wall ft off and about 1/3 to the right off centre. if I move it 6 " itsa noticeable drop off

It's a matter of subwoofer crawling.

With regard to the M5, what are you hearing that doesn't sound right?

I really really got to get into proof reading before I post

Its not so much what I am hearing and not hearing. When I did the measurements my graph shows big dips at 100 to 200hz
if I could post a pic here I would.
as for the sub, well I guess I could do that. just if I sit straight up and stick my neck 1.5 ft forward, Id have the perfect bass. nice n tight
