How does crazy Tyson spend a free Saturday? I'm glad you asked! He spends it doing crazy upgrades like this
Backstory. After taking the top part of my Super 7's to pretty much the limits of what can be upgraded, it occurred to me that the bottom/bass section had been neglected. And I also realized that the bass section plays up high enough for it to benefit from some love.
One thing that has always bothered me about the Super 7's is that, as fast as the bass is, it's never "quite" as fast as the blazing fast mids/highs. I just assumed it was a result of bass waves being larger and thus slower and I just wouldn't be able to fight physics. Right about that time I found some pure silver speaker wire in my storage closet. It dawned on me that silver has always sounded very "fast" vs copper wire every time I tried it, but always too bright.
Wait, thought, what if I use it on just the subs? Would they sound faster? Well, only one way to find out. So I whipped up the wire to some SpeakOn connectors and put it into the system between the amps and the subs. Oh wow. Very nice, definitely improved the perceived speed of the bass.
Next I take a trip to Danny's to upgrade my Klipsch Forte speakers and I bring along my new silver bass wire for him to try out. I get there, tell him about it and he says he can't use it in his system because there is about 4 feet of copper wire in the subwoofer amp itself and he just pulls it out and uses it, directly connected from the board to the back of the subs. DANGIT!!!! Oh well.
So when I get back home, what do I think to myself? I think "Hmmm, I wonder if I could just clip out all that internal copper speaker wire in the amp and just hook my silver wire directly to the board itself?" Yeah, that's not crazy at all!!!
Of course that's exactly what I did. I took some pics to document the process, but I strongly advise you - DO NOT DO THIS as it voids your warranty big time. I'm waaaaaaaayyyyyyyyy past my warrantee period and I'm also quite comfortable with a soldering gun and these types of mods. If you are not, DO NOT DO THIS.
For everyone else....

How does it sound and was it worth it? Sound is much, much better. The other thing I did at the same time is start to use a pure silver interconnect between my preamp and my sub amp. These 2 changes together have really elevated the Super 7's performance. Definitely STILL NOT at the level of the Lineforce, but close the gap by maybe 50%.
The best improvement, IMO is the integration between the lower mids and the upper bass. Before I've said on record that the one area of weakness for the Super 7's was the lower midrange power. Not anymore. I'm listening to Johnny Cash right now and DAMN his voice sounds INCREDIBLE now. The sheer heft and power when he goes low is just incredible. As good as the Lineforce? Again, not quite. But MUCH closer.
