WTB Philips AD5060 midrange


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.

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.

Hi mjona,

I found the AD 5060 SQ8 (8 Ohm version).
PM me if you are interested.

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.
