I’ve been planning these for a while, and finally they are done.

Each are fitted with a ICEpower 50asx2 inside. The crossover is split, so each crossover is fed with a dedicated channel. I mounted an aux input on each, so that each speaker only receives one channel.

Then I have mounted a chrome cast on each, and grouped them. So now they are truly wireless and multiroom capable.

Just waiting for new surrounds for the midranges.

Outstanding! A very cool update to a classic. I take it you're using one channel of the amp for the woofers and the other for the tweeters and midranges? Kind of what audiophiles call vertical biamping with passive xovers.

I think B&O should take a lesson from you, considering their speakers are all active, why should you need a TV or Audiomaster to connect them to, I think the market for stand alone stereo speakers like this would exist.

Leos that’s really cool! Did you put the amps inside the cabinets?

Is there no problem with heat generated by them?

Amps are inside the cabinet. Just below the bass reflex. Heat goes upward, so I think there is no problem. But for safety there is a fire extinguisher two meters away for now.

Do you have a thermal sensor you could run through the port and attach to the board/heatsinks temporarily to see? It's fortunate that Class D amps don't produce the same amount of heat as AB or even worse, class A space heaters.

I don't have a thermal sensor.

The amplifier is mounted vertically inside, and there is quite much space above it. I can atleast not feel the speaker getting warm in any way on the outside or in the bass reflex tube. If there was any heating problems I should feel the tube getting hot.i only have a few pictures, I'll post them from my iPad soon.

Otherwise I have been using them for a few days now, and they are working perfectly.

Total cost of the project was 160euros.

Well, being it's a bass reflex speaker, the harder you work the speakers the more airflow over the amps!

Bravo leogoeswild - I'm waiting for pictures. _________________________

I did a second rebuild today. Here are pictures of placement of the 50asx2, wiring, and input.

Took some video footage, so will put a video of it up soon if the footage is sufficient.
