@ricevs I’ve been thinking about your detailed suggestion for rewiring the Nenuphars and wonder why you wouldn’t just procure enough of the wire you are using internally to go from voice coil to amp, skipping "speaker cable" altogether?

The internal speaker wire is short and you can use a high quality one to replace it. For external wire, if you are content with the internal wire and never plan to experiment, you can always extend the internal ones externally as well but remember than the external wires are usually long (unless you are using monoblocks close to the speaker) and will need extra attention to shield and all. If you plan to experiment with speaker cables then its a pain to desolder/solder every time to change it.


Sure,,,,no probem.....but then you do not get to tune your system with different flavors of speaker wire. And, as debjit said....experimenting with wire is made very hard.  If you have mono blocks then absolutely you can mount them right behind the speaker and use the wire coming out and hook it right to your amp posts...using the wire tinned (no spade/banana....all connectors suck)..  


Most speaker wires are not shielded.

Direct wiring does have benefits, I’ve tried. Ricevs, let us know if you start that OB thread.
