Angled rings should work great although you might have to clear the dash since the pods are so close to it already.
Sorry, it's hard to capture the actual angle the ring is providing, but the XR3 is definitely pointing a lot less toward the dash. When I sit in the driver's seat, the XR3 from the passenger pod is almost facing directly towards me. There's still a small angle down to the dash, but I couldn't angle it any further up because the back of the XR3 is butting up against the pod with the angle.
Question I have is whether you (or others) know if there are any adverse effects with the angled portion toward the inside? Is there some negative sideffects that you know off with the speaker being in sort of a "tunnel" for about half an inch to an inch, especially towards the upper part? Not sure if that makes sense, so please let me know if it's unclear. Thanks in advance...
