Hello, In my experience the panel speakers from this era did sounds great when wall mounted because the drivers could be mounted at the right height for the best stereo image. I had a set of P45s which lost some of their clarity when stood on the floor. Regarding the 'quiet' sound I would be concerned about seized drivers. My first pair of P45s had this very problem - the woofers wouldn't move at all. It was like they had set rock hard. I acquired a second set which had perfectly agile woofers and which sounded nice and clear and as expected. Could be a similar thing with these. See if the seller can take the front baffles off and show you the woofers flexing by hand. Julian  

Thank you Pepps.

Excuse me but after thinking it twice, I'd like to be sure I've understood well: Are you saying the rendering is more affected by the height of the driver than the wall making some kind of reflector or resonator that compensante the box thinness? Is that right ?

Hello, The effect of wall mounting to improve the sound is in principal very similar to any non-rear-ported speaker enclosure. On a solid wall they'll sound stronger than on a stud wall or on brackets. Similar thinking to placing a rear-ported speaker on a nice solid stand. The writing from B&O on the topic does suggest something magical will happen, but it's just good sense to use a solid foundation on which to position the speakers. Get the tweeters at ear level and you'll achieve a lovely stereo image. Hang them higher and you'll get a more bass-heavy and floaty effect, depending on the amount of soft furnishings or reflective surfaces in your listening room. Julian

Thank you again Julian.

Hi Alls, Got the P50! First of all, they're big and heavy. Despite being very thin, they make My S45-2 look like a portable speaker! Second, of course and as expected the 4 woofer are seized. I extract the two woofers from speaker 1 and was able to remove the magnet quite easily. Now the battle is to stick him back with the right alignment. What I'm the most afraid is to damage the coil in my attempts. One of them already has the coil wire flying out of the base cylinder that only begs to be cut! I'm currently studying the Beoworld II forum about the better process to fix this. Stay tuned.

Hi, Still thinking on the better way to fix the magnet. In the meantime I'd like advices on something: the frets. They're in a coarse and stiff fabric glued on a thin panel made of wood and plastic for the wedge. the fret is fixed to the speaker with weird velcro strips, some in the groove in the edge of the speaker, and more wide bands in the flat surfaces of the front panel (those looks like added afterwards, not originals). The fabric is folded to follow the beveled shape of the wedge and not deformed like in the S45 or C30 I've seen. I'd like to know if this fabric is original or not. It is actually in not so good shape and the speaker will benefit of changing it all (once the drivers are fixed!) but if they are original, I'd rather try to rescue them. I've noticed P45, which seems to be technically identical have everything needed to clip their frets, like holes in the front panel which P50 don't have. So the two question I have are:

• Are those frets original (fabric and structure)?
• How where they originally fixed to the enclosure?

Hi, The two last days where tense. After glueing and testing the first woofer it did work well. Full on confidence and arrogance I went to the other one and I was punished for my pride. The coil wire broke, and it was a nightmare to manage to relink it. The tool for centering the magnet broke too and I had to take some distance before coming back (24h) and start it all over again. Fortunately, the second woofer is drying right now, the contact show continuity and read close to 7 ohms of impedance. It will be mount tomorrow in the evening I hope and I hopefully will be able to listen to one speaker. Regarding the previous question about the fret, I've found pictures on the net that confirm the the fabric is original. I don't know what to do with it right now because as original I want to keep those speakers, I can't see a way of attaching the frets without them vibrating. I'll see when I'll be there. A new question arises: the Phase Link driver, it looks like stuck too, no movement at all. I wonder if it's by design (I hope so because on my S45, it's not moving too). And also, why is that thing sticky? Cheers.
