Due to requirement for over 200 amps current carrying, the main wiring is 2/0 (four gauges thicker than 2 above). There can be additional concerns for lengths over 50 ft and of course only some wires are rated to safely/legally run through walls, such as the one you linked to.

Etsy’s 100% renewable electricity commitment includes the electricity used by the data centres that host Etsy. An important consideration is that the wire gauge is suitable for the impedance of speakers and the wire length. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.Personalised advertising may be considered a “sale” or “sharing” of information under California and other state privacy laws, and you may have a right to opt out.

Get the best possible sound from all audio components in everyday applications and home theater systems with Sewell's Silverback speaker wire.Both cables will also exhibit some series inductive reactance, which increases with frequency and length. The gauge isn’t the only consideration when looking into high quality speaker wire, better wire will have higher quality metals and increase conductivity. This removes one of the sources of mistakes (using the wrong probes for high current and voltage measurements) and makes it much faster to test multiple items. I am an electrician so losing strands is far more critical in my field than with speaker wire , but the concept and proper procedure are the same .
