I built my Super 7 monitors a couple of years ago. I made two changes today. When I first wired them up I used push on speaker clips in case I made any mistakes. Today I finally got around to solder the wires properly. My crossovers have a sonicap on the tweeter. I added 0.1uF Miflex KFPM-01 copper caps as bypass. The resolution on these things is unreal. I started with some Dave Brubeck and immediately noticed brushes slide, diddle, and bang on the snare which also sounded more real. I've heard this music hundreds of times but the brushes on the snare never drew my attention like they do now. It's like a focus knob got turned up. The sound is also less anchored to the speakers. It's a small change and yet remarkable for roughly $20 and a little soldering work.
