Speakers

[Seravee]

I'm trying to extend the cables of the rear-speakers of my Z-5500 set.

The user manual seems clear about the cables at first sight, "standard speaker wire, 18 gauge or better", the problem is wires at the store here aren't measured in gauge (AWG), but in cross-sectional area: mm^2. If I use a conversion table (link)

The standard wires here are either 0.75 mm^2 (the cable also mentions, max 50 watt speakers) or 1.5 mm^2 (the cable also mentions, max 80 watt speakers) .

Now if I would convert 18 gauge I would get 0.8 mm^2, which cuts it close to 0.75 mm^2. However, according to the user manual the speaks are 61 watt.

So, which cable should I use?

(I already have 0.75 mm^2 cable at home, I would need to buy the 1.5 mm^2)

Generally, the thicker the guage the better.

Hello Seravee:

Thank you for posting your issue to the Logitech Community Forums.

In your post you stated "Now if I would convert 18 gauge I would get 0.8 mm^2, which cuts it close to 0.75 mm^2".   If you took a look at this link you will see that 18 guage equates to 0.75 mm2.

but would it be a problem with the current load? Since the cable package says max 50 watt speakers, and the according to the user manual the speakers are 61 watt.

I guess it might just be for setting a standard, but I just want to be sure before I'm going to build the cables into the ceiling.

The front and rear satellites are actually 62 watts RMS, and the center 69 watts RMS.

Anyway, here's some info on speaker wire:
