It's not just wire size. Even the way you connect the wires (cables) matters a lot. Every fraction of an ohm due to poor contacts means several watts of wasted power.
That made this topic even more interesting. These will teach the readers how good engineering, solid foundation, and attention to details, can overcome difficult engineering problems.
In addition to power loses due to ohmic drop, another amplifier system parameters that will suffer when wire resistance comes into play is the Damping Factor. How this affect the sonic quality may spark another heated debate, and if it does, lets do it in separate thread para di magulo itong main topic .One appealing application that comes to mind when toying with amplifiers driving low impedance load is speaker box where the amplifier is housed right inside the speaker box. Powered speaker ba ang tawag duon? Short wire runs, soldered joints, and elimination of connectors solves some of the problem raised my master tintop.
^right on sir.. this amp should be used as near to the speaker as possible to avoid losses while maintaining a reasonable amount of DF.. it also calls for tons of NFB to have an equivalent internal impedance as low as possible..hmm, how about using a "sense lead" (ala laboratory power supplies)? it might cause instabilities at high frequencies, but if there is a way to apply it to low frequencies only, where DF really matters, then it could help.. some integrated amps have a feature like this, kenwood is one iirc, but i have not seen one in action.
no one is preventing you to use more pairs, this is diy, and there is no accountant looking behind our backs to slap our hands if we go over budget.....
Right... no accountant pero nan dyan naman si Mrs... Sobra pa sa accountant.
