I bought a pair of philips 22RH427 and one of the midrange is dead..
I am looking to buy one or a pair

I have a bunch of AD5060, none in the midrange sub-enclosure and all but 1 are 8 ohm. The 4 ohm one has a concave dust cap.

can you send me a photo to a private message from the 4 ohm? I am also interesting to buy a pair at 8 ohms
Does this come from the specifications or the sticker on the back of the unit - these do not adhere particularly well so if it has peeled off you would measure the resistance of the one in the working speaker.
This model of speaker was quite prominent in the bass region. The bass units are paired 8066W8 wired in parallel - the 4 ohm impedance would make these more sensitive than the other drivers if these were 8 ohm units.
There are 5060SQ8's on offer on ebay - some pretty shabby examples and for silly money. There are specialists in speaker repair who could replace a voice coil for less money.
I have a vague feeling 5060W's are pretty much the same speaker minus the sub - enclosure.
Hi mjona,
I'm pretty sure that I have one NOS AD5060 in my storage.
I can check tomorrow if you are interested.
Edit: The coated midrange version.

From the service manual I found that midrange and tweeter are 4 ohms and two woofers in parallel 8 ohms each one.
The midrange in the back of the sub-enclosure has a sticker AD5060/SQ4, I think inside has a AD5060/W4
I will also check for sure inside the elclosure tomorrow
I found a lot of AD5060/W8 on ebay but non AD5060/W4
Presumably you have done a test for continuity between the solder lugs at the back of the sub enclosure to eliminate the possibility of a fault with the series capacitor or solder joints on the crossover board.
You could check if there is continuity to the voice coil inside the sub enclosure with a meter and a visual inspection of solder joints etc. You might find something adrift that you can remedy yourself. If not my inclination would be to have the voice coil replaced by a speaker service specialist.

Sorry, my mistake.
I intended to address alexanderfa. But since I have the 8 Ohm version I guess it's a no go.
Alexanderfa,
Thanks for the deal. I hope your mid range speaker will arrive soon (package left Sweden Wednesday).
Clio measurements prior to shipping,
Impedance:
Frequency response:
Quick FR measurement (little time and cramped measurement space). Distance 0.5m and no baffle (explains LF drop off). Distortion raised 30dB.

Hi Roger,
Strange that impedance picture is gone. Probably a glitch during forum upgrade.
I should have impedance plot but it may take a few days to retreive it. I'll get bet back.

I have found some data but they do not match with my AD5060/W8. I think they are for AD5060/SQ8. Seems to be a few versions of the AD5060. Some have Fs = 50 Hz, others 65 or 200 Hz.
