S752A EPS/Individual Audio System Subwoofers

The subwoofers on my 2011 E92 M3 equipped with EPS (S752A) recently blew. After countless hours of searching through forums, it seems many (outdated) threads suggest replacing them with Bavsound's Ghost V2 subwoofers (8ohms). I contacted their SA and found they no longer sell this product for the EPS systems due to "disproportionate amount of blown subs...even after matching the impedance."

So a couple of questions:
1) Any long term owners with the OEM EPS amp + Bavsound Ghost V2 subwoofers (8ohms) who can confirm if this is really a common failure? These still seem like the best, easy option.
2) Are there any other plug-and-play subs to replace the OEM 8ohm subs, compatible with the OEM EPS amp? Looking for options where I don't need to do any wire splicing, soldering etc.
3) Where can I buy new OEM EPS subwoofers (8ohms)? I'm having trouble finding them.

Thanks in advance.

I have the BSW 8ohm subs and have had them for probably four years. They are still going strong. I wouldn't consider them an upgrade though. I actually preferred the sound from the stock subs better. I would have kept the stock ones but sold them when I got the BSW subs.

thats good to know! so many people talked so highly of the BSW.

I guess I'll continue my search for the stock subs.

It really is too bad no one is making 8 ohm subwoofers. The EPS system subs are 7 ohm but I guess 8 is close enough.

There's people on some other threads using 4 ohm subwoofers with EPS. There are a lot of aftermarket 4 ohm stock replacement subs. I guess you can turn the subwoofer volume down and it should be ok?

It really is a shame... In any case, I found a way to fix my original subs by soldering on some new wires where it broke. Speakers work fine now.

I thought those using the 4ohms subs were also using alternative aftermarket amps (like JBL)?

Eton B150 underseat subwoofer is a direct plug & play replacement for Individual Sound sub. I've had mine for 5 years / 50k kms no issues. They provide much better low end which is missing from the Individual system.

Aren't these Eton B150 subwoofers 4ohm? The EPS subwoofers are 8...

These are some of the people using the 4 ohm ones with EPS. I don't know anything about car audio but I guess it can be done?

No clue. One of my subs died (water damage) and the shop familiar with BMW sound systems recommended these as PnP replacements. They've been in my car 5+ years now and are great.

Has anyone tried the new Bimmer Tech 7 OHM underseat subwoofer replacement yet?

https://www.bimmer-tech.net/speakers...lifier-for-bmw

I think they're the only ones out there that are actually matched to the factory impedance spec. They're a little too expensive for me to take one for the team but curious if anyone is running them.

Wow! these look pretty new. Nice find! Looks like a good option for individual audio sub replacement.

The pricing is the same as the BAVsound subwoofers when they sold them.
