Hi just wondering if anyone has the schematic for the Jamo concert 7 ?
The 1989 version with two 8" internal bass drivers.
Thanks 🙂

Not sure if "89 verison but if someone wants, can make it to regular schematic.
Idk if the 4.7uF mcap is correct.
At this age bipolar could be easily out of spec.

An externally hosted image should be here but it was not working when we last tested it.

Please help me out
Hi I just stumbled over this thread
and yes 4,7µF is correct as far as I can tell by some of my pictures.
I am actually just looking for a crossover schematic. Please help me
The Tweeters come from SEAS: H400 25 TAC/G and can be replaced since some newer generations are still available on the market.
Thank you

Have no schematic for it but if you wish can draw from image to schematic as there is rear and front image mirrored.
I lately replaced all caps in filter with new mcap as midranges were sounding slightly different but actually only bipolar caps were out of spec badly. Those 4x 72uF bipolars probably were not made to last 25+ years. Other caps poly type were all in spec.
I have tweeters replaced using H0883-06 27TAFC/G H0883-06 27TAFC/G
Not sure if it correct replacement if crossover not altered but if H400 25 TAC/G is original model then can compare specs.
Tweeter can find some replacement and midrange looks visually same as concert 5 but if woofers fail it may be compelx to replace.

The original Tweeters are from SEAS:
H0400 25TAC/G

the right replacement would have been the
H0417 25TAC/GW
http://www.seas.no/images/stories/vintage/pdfdataheet/h0417_25tacgw.pdf
I was thinking about yours aswell for my next tweeters >> those are the current gen. replacements for the H0400 the specs fit except the powerrating which seems now better for the Concert VII
H0883-06 27TAF/G
http://www.seas.no/images/stories/prestige/pdfdatasheet/h0883_27tafc_g_datasheet.pdf
As far as I know the Midranged one (W-20482) is the same on the Concert V
Woofers(W-22168) are wired in parallel but one woofer is obviously connected with interchanged + -
H0400 25TAC/G

Made schematic from the board image , it may contain some mistakes.
Also no correct values for inductors.

Change the crossover Jamo 707?
I have a problem! A friend of mine came with a Jamo 53508 crossover. He would like to change the output from bass+mid, tweeter to bass, mid+tweeter.
Is this possible? When I look in the schematic they have to many components in common. Isn't it easier to build a new crossover?

I have the speakers... refurbishing (refoam basses) atm.
Happy to take detailed pics/measurements- would that help any?
-smiles from Norway 😛
I think since all the previous images have gone.
If you could take lotsa pics and post them here via the diya servers, that would be an awesome resource for all 🙂

OK, I'll be happy to share. How do I upload to diy servers?

Hi! I'm about to restore my old Concert 7´s, and I´m very interested in the crossover schematics. If you could upload them, or PM them to me, I would be very happy. Thank you🙂
