How safe are mains converters?

Why would there be a problem?
Transformers are used all over the place without incident.

EDIT: Nice speakers by the way, I have a set and they are pretty decent.
 
Thanks for the info :) And yes, what she said, about it being cheaper.

My only concern is where to put the sub, as it has to be at least 60cm away from other electronics and the control unit has only got a 2 metre cable.

Yeah should be safe. 230 to 110 isnt too stressful. Look at your phone charger, that 230 to 12 ;)

Completely different scenario, completely different method, completely different outcome. The 12v will be DC not AC.

However, it is perfectly safe to convert 230v to 110v.

They're safe otherwise they wouldn't be allowed to sell them. If it's really 505W I'd use a 2000VA converter at least...

2000VA converter :eek: Sledgehammer and nut spring to mind!! lol (Also a 2000VA 110 step-down transformer will cost about £170:eek: where as the more suited 500VA one can be bought for £55-£60)

Those speakers will need 3A @ 110/120v 60Hz
A 500VA converter can supply 4.1Amps @ 110/120v so it's safe to say that a 2000VA converter is miles too big for this!!

Is that because logitech still don't insulate their speakers?

I've got the X-530 set and whenever someone switches a light on, I get a pop in the speakers :|
 
Not sure what you mean by insulate or about how subwoofers normally operate, but apparently this one has two very large magnets inside and thus can cause damage to electronics (mainly hard drives).

lol
Pretty much all speakers have magnets in them, thats how they work.
However if I was paying that sort of money for a set of speakers I would expect them to be shielded so that they can be placed close to other electronic devices without effecting them.

Well I figure unless the amp is class D then it will have efficiency of around 50%.

500W out = 1000W in, but I figure it's better to have some headroom...

Anyway, really I doubt you'd really need the full 500W, and people don't really listen to sine waves (at ear splitting volumes), plus I'm not really sure how the 505W rating was actually measured (could be 1khz with 10%THD), so I guess a 500VA would probably work...

It may be worth picking up one of those power meter things to see how much juice these speakers use, personally I'd go for the UK or euro version even if they are a little more expensive....

EDIT: If these speakers only need around 330W (110v @ 3 amps) in then it's safe to say the 505W rating is BS. ;) Many 500W PA amps will blow fuses in kettle leads if they have a 3A fuse, and this is 240v....

Ah okay I see what you mean ;)

I guess my sub isn't as powerful, my 'lextrix are all working fine with it nearby :)
