I have added a couple of pictures, one of my stands with spikes and the other a close-up of a machined disc spike protector.
The question I have is what effect will altering the height of the speakers using spikes change resolution and imaging of the speakers?
In the XPL manual it states using stands to help improve the overall sound by lifting the speakers off the ground as well as tilting the speakers back a few degrees towards to the listener.
I have noticed that since adding the spikes, I seemed to have lost some resolution and imaging. I have measured spike clearances on both speakers and all have increased the height of the speakers by 2cm or 20mm all round.
Is there a set rule or has JBL released any literature as to how much spikes should be rasing the stands or speakers off the ground by?
The only solution I have come up with is that the spikes have increased the listenig height to that of above the listening position normally set by using stands only.
If I have increased the height of the stands at the front by 20mm, should I be adjusting the spike at the rear of the stand so as to tilt the speaker more towards (forward) the listener? This is the only change I can think of performing that will fix my resolution and imaging problem.
Any thoughts?
