Bang & Olufsen Beoplay A9 MK 1 Disassembly process and Repair guide

#danishdesign #repair #service #soundsystem #speaker #hifi
The distinctive shape of the Beosound A9 is meant to be flaunted. It's a minimalist masterpiece from a distance. Close up, the details shine. Like your best pieces of furniture, they are the focal point of any space. It also elevates the level if you would rather have it on the wall. Whether you choose to hit play or not, take in the beauty from every viewpoint.
The Beoplay A9 uses acoustically adjusted coverings to convey your music while standing firmly on natural oak legs. The design is an unending cycle of engineering and art, underpinned by premium polymers and framed with precisely machined metal.
All parts will be taken apart one by one and can be founded in our website.

Love the big peerless sub, the beosound theater uses the same woofer but a 6.5inch version instead of the 8inch

[@KoseTrading]

I did't know thatBang & Olufsen had integrated the Beoplay A9's, peerless sub driver, into the brand-new Beosound theater.

[@speakerblowupmanlee5921]

Nah those 6.5 inch subs used to be on parts express for like $50. Sad they're out of stock now.

@@speakerblowupmanlee5921 So it was not used in the Beosound Theater?

[@speakerblowupmanlee5921]

@@KoseTrading it probably was. Could be the reason it is out of stock.

Hey, I have a MK2 that over time lowers the volume. I've read that this could be a overheating protection, however the speaker is not any warmer than normal. I've read the service manual for the 3rd gen, and that specifies a NTC module which I assume is resposible for measuring the temperature, and regulating the power output. Are this also present in the first generation?

[@KoseTrading]

That's a very common problem with the MK1 and MK2 version for Beoplay A9. You can try to clean out the amplifier and see if that helps.

[@jacobtc]

@@KoseTrading Okay, I've read that a new mainboard might be needed, but reading the service manual, I see several NTC's, one on each driver, and again some on the mainboard connected to the MCU. Do you have any experience fixing boards?

[@KoseTrading]

@@jacobtc Yes, we can try to fix the problem on the mainboard and also the amplifier board. Send us a e-mail to [e-mail]

I have the same problem with my MK2. Looking for a way to fix it.

My daughter have a A9 MKII and it has frequent "crack" sound sometimes during play, and more often when the unit has been used and "cooling down". Do you have any advice? I read somewhere one solution is to lightly unscrew the screws on front to release tension. Any advise?

[@KoseTrading]

Thank you for your comment. Yes, I also heard about the "crack" sound coming from the chassis. Lightly unscrews can help, what I had experienced in disassembly process for Beoplay A9 that the screws a very tight. It can maybe help with the problem.

Great video! I have an a9 that developed a burning smell, it’s 12 years old. Any ideas what that could be? There are no error lights and it still plays, but I left it unplugged in a room corner for 12 months

[@KoseTrading]

@@Markymark1408 The burning smell can come from the Power supply board or from the drivers.

[@Markymark1408]

@@KoseTrading great thank you, in either scenario is that an expensive fix? Time to get a new model?

[@KoseTrading]

@@Markymark1408 I will try to fix the beoplay A9 if you have the time.
