Not sure if it would work, but what are you trying to achieve with the extra speakers anyway?  If you want extra channels then why not just buy a Passive and power the Beovox 4500s from that?

I thought about that option, but this is quite difficult due to the needed wiring. 

This is the result

Hi Bieele,

That looks superb!

You just need to be careful not to overload the amplifiers, ie. don't turn them up too loud.  Maybe someone has the spec for these amps, so that we can identify if they can cope with a nominal 4 Ohm load at higher volumes?

Kind regards, Steve.

Thanks for the reply.

Next to the looks, I am also happy with the sound; I tested them for the last days and did not experience any problems. Seems to work, but it would be great if someone has the spec for these amps to verify.

Regards,

Dennis

I must say this looks very nice! If you can get your hands on another pair with different color cloths, you could try comibining different colors!

The service manual for Beolab 3000/4500/5000 (on site, available elsewhere too) has specs for 3000 and 5000 and it says:

Beolab 3000 (Type 6711, 6712, 6713, 6714, 6715) Power Amplifier: Long-term maximum output power: 90 watts.

How’s this working?  Still ok 4 years later?
