Problems replacing electrolytic capacitors on my Eosone rsf-600 dipole speakers.

I played Gila Monster by KGLW and I noticed  the mid to highs sounded horrible. I was ready to give up on them until I discovered the problem with electrolytic capacitors drying up. I replaced the 16uf & 100uf electrolytics, both in the high pass due to dipole, rear tweeters, with dayton polypropylene capacitors. The sound came back alive in my speakers. Now, the issue I face is when I turn the speakers to a high volume, there’s some dampening and distortion going on in the high frequencies. In order to fit the 100uf & 16uf poly caps, I had to cut about 5" of 16 gauge ofc so I could sticky mount them to the side of the cabinet. I’m good at soldering so that’s not the issue here. I really love these speakers and will do anything to fix them. Any help or advice would be gladly appreciated. The original electrolytic caps were made by tecate, 85°C, 50 v, 10± 100uf & 16uf. 

Arnie Nudell & Paul Mcgowan really knocked it out of the park with the Eosones. These speakers have become meaningful to me due to the history behind them. Long story short, they loved music, specifically operas, and hoped to enrich America’s flailing art and culture scene.
