14/4 wire for speakers- good idea? Bad idea?

Is it Canare 'star quad'?

That stuff always worked well for big bar installs. Used to buy it by the roll....

High end manufacturers don’t use this configuration, AFIK. (talking about starquad and equivalents)

It’s just that it is excellent and right in the correct area of design and requirements for big clubs or house systems, or concert performances, traveling road shows, etc.

Pro does not equal ’good’ or ’best’ ....It merely equals the requirements for pro use in ways that work and don’t fail. Functionality and not failing, the two big points. Performance quality is third or lower on the list.

If anyone asked my opinion on this for high end set ups, I'd say no, don't. For a few dollars more or spent differently, far better audio quality can be found. Star quad and equivalents are for ripping your face off with long term all day +1kw peaks on bass bins, flying monitors, 50-100 ft runs, and so on.
