I just got my PCF 905AS. First surprise: they are not heavy (my back will be grateful). Second surprise: although not broken in yet, they have a huge dynamic range so I guess the sound ought to get very good after some hours of operation...

I'm back with a new post...

After a few hours one speaker produces AC noise at 50 Hz.

So I'll go back to the dealer to contact RCF's after sale service...

I'm back again: I just got the third speaker and it's a BIG DISAPPOINTMENT because the problem is worse than on the second speaker!

The 50Hz noise is actually louder and an additional hum can be heard. It's very strange for a subwoofer, isn't it?

I'll go back to the dealer.

I'm starting to lose my faith in RCF's quality control.

To be continued...

It's me again:

I called the RCF representative and I was positively impressed by his commitment.

Congratulations.

He proposed me a solution right away.

I have an appointment on Friday, HATS OFF!

I'm confident they will find the defect on this HMX series...

The HLX series works great...

See ya!
