Crossover and Wiring Upgrade
@stillbuyingtoys Your Thread Title, leads onto an inquiry about internal wiring, and binding post? Of which Internal Wiring is used on two occasions.
I have made reference to Wire Types that are very worthwhile being considered for use within the Speaker Cabinets Interior and Exterior.
The suggestion was also made to consider not only a Improved Quality Connection at the Speaker but also on the Amp’.
The Cost of one wire type referred to, for use Internally does not need to be excessively expensive, as the Link will show.

If my Google Translate has not remained in English, a right click and select Translate will allow a little further reading on the properties known with the wire type.
The info shared in the Link pretty much shows why the Wire Type was wrote as it was when it was first referencedt.
As for the Connector at the Cabinet. The link has a broad range of designs and costs.

My own math at the moment suggests the exchange of a insitu wire to the referred to Wire Type and exchange of insitu Connectors on Two Cabinets, is achievable for $130ish if using Pure Copper but not getting too caught up with the Brand.
