I am considering an ob subwoofer using a pair of gr drivers, as you might notice from my other posts and I found this video showcasing a pair of subwoofers using the GR drivers and Rythmik amp. It is as simple as it can get, back to back, placed on floor vertically -I guess they must have spacers between floor and driver frame- I put on my headphones to listen and it was impressive.
So, my questions are, has anyone seen and heard this, and is this implementation technically right? I realize that the driver pointing downward has a different load to Th one on top point up.... And that this might not be optimal, but I like the idea.
Thanks guys!
