Well, I am about finished with my SRS upgrades. All has gone well and the SQ improvement is truly astounding. I will report in much more detail once the job is complete and I've had an opportunity to do some good critical listening. Well, yesterday the last item was to change the large 16mH inductor as reported on by DarqueKnight. When I first powered them up with the new NorthCreeks I could immediately hear a significant difference in the bass response which was more tactile and very clean. I also think I get at least another 1/2 octave out of the PR than before. BUT, my soundstage has shrunk dramatically . On one track in particular where there should be music at almost 90 degrees to my listening position it has moved almost all the way back to the speakers. Most musical content is now confined between the 2 speakers ? not very SDA like . I have used aluminum hardware to mount these on the brace that separates the dimensional from the stereo drivers (brace runs down the middle of the cabinet from the top almost down to the XO?r) midway between the front and back of the cabinet. My thought was to mount it as much as possible in ?no mans land?. This inductor is heavy and needs a significant mount, which doens't leave a lot of options. Either these need to burn in A LOT, or I need to move them somewhere. I?ve even thought about drilling a couple of holes and mounting it external. If I can?t find a fix I?ll go back to the stock inductors and I?ll have pretty cool looking pair of very heavy and expensive paper weights. Any ideas would be appreciated.
