Re: Grundig speaker drivers

Thanks for the info Massimo. I'm curious, did grundig manufacture speaker drivers for other companies in that period?[/quote]
Seems like in that period of time grundig r&d was huge.

Re: Schema originale crossover Box 850-850a

That was my suspicion too.
Luckily I found a set of crossover locally and inductor labels matches the schematic.

Re: Schema originale crossover Box 850-850a

My speakers are box 850. It has no fancy flanges or marks on front baffle. Both crossovers are the same. I have several Grundig speakers; box 550,650,850,306,sl1000a. I have suspicions about this 850, because somehow bass is stronger in 550 and 650, but 850 bass response is poor. I checked Dr1 again...

Re: Schema originale crossover Box 850-850a

I have a box 850 and its crossover is marked as 19310-455A. Inductor labels are different than the crossover schematic in this thread. According to schematic; DR1 016.01 DR2 014.01 DR3 020.01 DR4 014.01 My 850 crossover inductors labelled as; DR1 007.01 DR2 014.01 DR3 013.01 DR4 013.01 Any idea why?...

Re: Grundig V7200

I mean; bottom pcb traces are destroyed. Service manual has bad scan quality, traces are not clearly visible. So I need something to compare. A photo of undamaged pcb traces for an example. If this is not possible, I have to trace schematic.

Grundig Box 306A

Hello, Last week I added this box to my lovely speaker collection. But I couldn't find any info about it. There is no information on Grundig catalogs. I found compact box 306 but this one is totally different. Anyone have any info about these? https://www.audiovintage.fr/leforum/download/file.php?id...

Re: Reverse Phase Drivers?

Thanks for the replies. Ambrosini, is this a general rule for three and four way speakers? I saw the box 850 crossover schematic and tweeters definitely reverse phase connected. Do you have other box schematics? 550,600 or 650? Why I'm asking this; because every Grundig speaker that I acquire has so...
