Thanks, guys. I was specifically asking in reference to its application in a subwoofer and an open baffle sub at that. I thought maybe since Jay builds more of these than anybody else he might have listened to them with and without.
I have heard different sets of these, some with, some without no-rez but I've never had say a set of duals with and set without to do a direct a/b comparison.
I listened to a set of duals I through together for temp use with no no-rez..... had them in here for a bout 2 or 3 months and they sounded great. Had I ever gone and finished them (ended up using for another project) they'd have been treated with no-rez because I do believe there are improvements.
As mentioned, we use it for all our finished cabinets/speakers.... have done so ever since I first used it back with my Ob7 build.
It's money well spent.
