Sunfire subs

It seems that whenever someone asks about a recommendation for a sub it's always Velodyne, Rel, HSU, Rythmic, etc. Sunfire is never mentioned. Some years back, when the TS-EQ12 came on the scene I read an article in TAS that paired it with the Mag 3.6's and called it the proverbial "match made in heaven". I had 3.6's at that time paired with an M&K sub. I bought the Sunfire and it was like night and day. I now have it paired with my Mag 3.7's. I was wondering if there's something wrong with the Sunfires. I've never had a problem.(knock wood) Why do they never get any attention?
