I have a 2023 X5 with the Harman (688A) system.
Long story short... I was not happy with it.

I had the Match 10DSP installed.
I kept the stock speakers for starters.

The sounds is much, much better now.
Not perfect, but the loudness, the fullness, the bass is there.

Are there any X5/Harman owners with Match 10DSP installed?

Can you share your Match10DPS profile?
I would like to look at it, and see your settings.

Also, could you please comment if you are happy with it?

----

I ended up doing my own tune.

It took about 1,5 years... let me post my settings.
Hopefully it will be useful for someone.
Feel free to ask questions.

Sent you a PM.

Thank you very much.
I uploaded my tune file too, if anyone needs it or is interested.

Do we have any G05 with Harman / AlphaOne users here?
Can you guys share your tune file?

Never seen the Match amp before. Is it the same as the AlphaOne? I am going to go full AlphaOne soon. Would love to hear about anyones experiences with the amp or full monty over the stock harman system.

If I'm not mistaken, the OEM Harman Kardon can be replaced with the following plug-in option:

Match UP10DSP processor amplifier + incl. MEC ANALOG IN
Front speakers in the front doors MATCH UP C42BMW-FRT .3
Rear speakers in the rear doors MATCH UP C42BMW-FRT .3.
Midbass under seats MATCH UP W8BMW-S
Surround speakers in rear pillars MATCH UP X4BMW-FRT
Center channel in torpedo MATCH UP X4BMW-CTR.3
PP-adapter MATCH PP-BMW 1.9RAM-HK

As far as I know, the Bimmer-tech AlphaOne Amp is the same at the Match by Audiotec-Fischer. I think AF is the original manufacturer, who also makes the DSP Tool software.
Bimmer-tech probably rebrands it, plus provides support + files.

There is a steep learning curve to the Amp. It is not a simple plug-n-play device. But it can definitely improve the experience compared to the stock system.

I am very disappointed by the HK system. The stock system does not have a very good sound. I think it needs tuning. Plus the Subs are way underpowered. Not exactly sure why... at this price level the HK system should be much, much better.
02-20-2024
Thanks @ dombi
Will get the amp first and then tackle the speakers later.
I think the HK system is OK but agree it lacks real high end SQ.
We have a very high end home system and would like better sounds in our lovely X5.
I just loaded a 1TB thumb drive with several thousand ripped CD FLAC files which made a big difference over the music on my iPhone which is stored as ALAC files. Either through CarPlay or I-Drive usb.

Quick update: I had an appointment today to get the Subs upgraded.

I got the MATCH UP W8BMW-S Subs installed:
https://www.audiotec-fischer.de/en/match/speakers/up-w8bmw-s

The kit came with the pair of speakers needed to replace both Subs under the seats. The new subs are 2 Ohms, compared to the old one's 8 Ohm.

Sound levels were adjusted. Timings were set.
The system was also EQ-d using the PC DSP Tool.

Wow!

What a night and day difference. Everything sounds amazing.
Sounds are loud and clear. The whole system fills the cabin.

And I just listen to Spotify over CarPlay. Higher quality file probably sound even better.

This is what the system should have been like coming from BMW.
02-21-2024
I also have to say that I have an X5 with the HK system. The mids and highs are fair, but the bass is really lacking even with me fiddling with the equalizer and settings. I may look at the Match subs that you mentioned as a replacement.

I can only talk about my experience.

When I took delivery of the car, I was very disappointed in how the HK system sounded. Then, as days/weeks went by, it got used to the sound. Some song sounded better then others. But it just never sounded good.

For the Amp + Sub install I was there the whole time. I watched the whole process and I talked to the installer.

I am not sure why BMW went dow this route with the HK system. IMHO the stock system should not have been released like this.

Getting the Subs + Amp together really made a really big difference.

The HK's stock Amp is underpowered, and there is no way to tune the EQ on it. So even if you replace the Sub, the sound probably still won't be as clear.

In the Amp, with the individual speakers adjustments, with the EQ adjustments, I can finally hear the little details in the music, once again.
You can really tune the sounds to your liking (improve it a lot more for the rear passengers for example).
Now the sound really fills up the car.

AlphaOne is a rebranded Match amp. Bimmertech was very open about this with me.
It costs a bit more b/c they will tune it for you ahead of time and they build their own wiring harnesses to make it an easy at home install.
There's some weirdness about how the LCI checks the sound system and will brick the Driver Assist Pro if it notices an anomaly.
Bimmertech has built their wiring harness to work around this by working with one of our board members.

I am curious if Bimmertech uses Match subs as well.

Thanks for this. I have the Match10DSP from Bimmertech. The tune they sent me with the amp was definitely an improvement over the stock HK but had some shrill sibilance, which I was looking to fix.

I finally got a mic to do my own tuning but once I hooked up the laptop, it did a firmware update on the amp that appeared to erase the tune Bimmertech had put on there. I tried to download the stock G05 X5 tune from Audiotec-Fischer website but their tune download page is down, and thus turned to Google whereby I found this thread (I'm sure I could email Bimmertech and get a tune but this was here and now).

I took your tune and then just applied the RTA function in the DSP PC-Tool software for each output, which seemed to do the trick. I probably should have checked to see that you had the outputs set up properly, so uh... please let me know if you later found out that you didn't... but now it seems to be improved overall. So, thanks!

Wow. You found an old post from me.
I am not sure which tune file is shared here.
But it is definitely an old one.

A lot has happened since then ...

Not sure which software the Amp is using.
FYI, Audiotec Fischer is working on a new PC Tool, version 6.x.
It is out, and available for download, but do not update to it yet.
It is still buggy.

I am not sure which version you got from Bimmertech. It is probably version 5.x. I would definitely stick to that, and stay away from the 6.x for now.

Yes, when you do a firmware update/upgrade on the DSP, it will erase your previous settings. Always make sure that you have a local copy of the save. I have a separate folder on my PC, where I keep my tunes.

But again, try to stick to the PC Tool software version that you have. Which version do you have?

I tried to use PC Tool's built in RTA, but for me it was a bit confusing.
But many people use it with success. There are YouTube videos on it.

Socket has a great YouTube channel, with lot of tuning videos.
https://www.youtube.com/@socketsocket2763/videos

Take a look at them. There is a video series where he goes from the beginning, step-by-step, and does a complete tuning.... you can try to follow him.

What speakers do you have? Factory HK or did you upgrade them?

I just got the PC Tool from the Audiotec Fischer website (version 5.x). I thought the RTA tool was fairly simple... or perhaps I just didn't mess with it much beyond the initial measurement.

I never had a tune file to begin with, other than what Bimmertech had preloaded on the amp. So I nothing to backup from, although I'm sure they would be willing to share a copy.

I've just got the factory HK speakers. Don't know if I'll make any other upgrades. I've got the 50e so there is no spare wheel well for a subwoofer.

Great! I think that the Match UP Amp/DSP should be the first step for anybody that is looking to improve the sound.

If you are happy with what you hear, then it is great.
If not, i am sure that it could be improved.

You can do a lot with a Measuring Mic (Umik-1 or Umik-2):
- time alignment is the speakers (with PC Tool's built in Auto Time Alignment)
- EQ of the speakers

These would improve the sound. Then it gets a little more complicated.
Aligning the Woofers. Adding a Sub.

By the way, the Audison Sub I have, comes in it's own enclosure box. Which is quite sturdy. You can even place things on top of it, it needed. You can move it around the trunk, or even remove when you need the space...

I have experience about Bimmertech's base tune for a G05, and of their remote tunning, I got the Match UP10 DSP, from them, so the Alpha One in their language, as well as their full speakers package including all drivers and both subs, it was upwards of $3.5 K Dollars. Had them professionaly installed and...

They have a base tune that does not even address input signal analysis, so it sounds not good at all. And when you ask for their so called remote tune, you get a guy on the phone, you have to hook up your lapton and a remote PC connection to the DSP/AMP, but there is no tuning microphone or way for them to check the tune. Then he asks:
- What do want to change?
- Well it sounds really harsh, makes my ears hurt after a while, high frequency sounds are percing.
The guy just does a basic high shelf filter and asks:
- How's this?
- Uhhhh, it sounds almost the same as before.

Then you realize this process would get nowhere, it'd just be a waste of time becauese you need a Proffesional tunning mic for a remote tune. The solution could only be a full tune where frequency response peaks (or cabin gains) are addressed and leveled.

As far as their speakers quality, I would only recommend their underseat Subs at 2 omhs, the rest of the drivers seem to me as quite similar to the H.K.'s. But at $650 for the subs, it may be best to get the Match or Audison, plug and play´s for BMWs.

For a lot of our customers, the slightly modified base tune is enough for what they are looking for. We do occasionally do a full tuning session with a microphone for those more demanding customers, so we do encourage you to get in touch with us again to schedule one to make sure you are fully satisfied with your purchase. If you do not have a microphone, we are also able to lend one out to you.

All of our tunes are signal analyzed to specific headunits and sound systems. They also all have time alignment set for the driver. Some more common chassis, like your G05, also have their own tunes.

With just the Match UP 10 DSP, and keeping the factory speakers, the system can sound really good. If tuned.

Once you know the steps, tuning is actually not that difficult.
But there are quite a few steps. And they have to be "more or less" correct, otherwise they might ruin the sound to some level.

You can make a hip hop song sound good-ish... but have really bad overall sound for rock music.

So I agree with Joey. To make a good tune, you need a Mic.
You have to measure your system. You need to see what you are working with, what the system can do.
Then you have to make corrections, adjustments. There are quite a few tricks... but it is really not that difficult.

And if you want to make it sound really good, then you need to measure impulse and phase too.

That remote tune with a mic was not an option before, nor do I see it in the BimmerTech website, nor was offered to me when I reached out for a tune, but now it's good to know about it. Thank´s for the offering, but I do not need it anymore, I am quite happy with my own custom tune.

Thanks for the info. Might you be able to share the tune file after you installed the Match subs? I just installed the amp and subs so pretty much same set up.
