Hmm that certainly has my interest, hopefully they will have a remote available as well?

Full disclosure, I'm one of their beta testers and listed consultants.

Thnx. Will have a look at it

No remote but they are working through volume depended loudness on bass as an option.

In their release notes for one of the software versions it mentions a couple of prototypes. If released this would be BMWs individual audio system on steroids which is an active setup to each speaker..

But with the DSP does support the factory equaliser/ bass / treble over the top as well digitally if any of those need tweaking to bring bass up at lower levels.

Bill had a great graph that shows the perception of bass at different volume levels.

Yes sorry, forgot that it was full audio spectrum.

Don’t get the iPhone app called spectrum BTW if you see it, looks ideal, but hasn’t kept up with Apple phones mics as the new models have come through. The other thing to note is the apple mic on my iPhone 13 doesn’t give any detail below 40hz and Bass region isn’t that accurate.

It's wonderful to have those features (I'm a very big fan of variable equalization according to loudness), but I'm really looking for remote level control of a trunk subwoofer. Different genres of music can use a bit of a "tweak" of this level (I listen to all kinds of music), plus when my kids are in the back seat, they appreciate when I take the trunk sub level down.

Audiotec has a wonderful Director remote control, and many car audio amp manufacturers offer at least a potentiometer level control of their amp. The 100 Hz eq control on the iDrive tone EQ settings is woefully inadequate for subwoofer level control, I feel like I'm using a chainsaw instead of a mitre saw to cut trim moulding, not enough frequency resolution.

Mobridge checks almost all the boxes with their K2 8.1.1 MOST dsp amp, but not having a remote of any kind is a glaring omission on their part. I inquired of their tech support email, but so far, when pressed for an answer...crickets.

I do know that Studio Six Digital does a sampling of built-in iPhone mics to get a representative compensation curve which is reasonably accurate for measurement purposes, but also offers an external type 2 level mic that is calibrated for use with the software that is rather affordable. I use both in my daily work because they conveniently fit in my pocket/briefcase, along side over $40K of other audio/acoustic test gear that I use in work that justifies a higher level of reliability.

Sure, used to have a controller on previous DSP.

But you can also achice a sub boost via factory eq. Just that alone it is quite effective to go between a Harman style and Whiteridge style house curve. Or to get sub bass only boost base and do a eq cut at 200 and 100 hz.

I simply have two dsp maps loaded though which is toggled by the the idrive assignable buttons. One for passenger and one for me. I Just press button 7 on my idrive to flip it.

Not exactly what I'm looking for, but I certainly can accomplish part of what I want with two presets that I can toggle between. Seems like the iDrive bass control is a bass shelf that affects the entire output, and the 100 Hz frequency control hits it a band that is too high for a trunk subwoofer.

If only mObridge would provide a proper GPI or remote port on their amp...

Bass does run to 300hz but a quick cut at 200 and 100 hz and it’s hitting harder in the sub bass region only. I have eq assigned to button 6 for quick access, not as quick as a bass knob , but quick enough. But remember, the ethos of the Mobridge is full OEM integration. I don’t miss running a controller.

Are you saying there will be a 10+ channel amp fome Mobridge coming soon?

I will be in the market soon to upgrade my 2018 f36 H/K system and want something that will power all drivers plus a 10" sub.

[NealfromNZ]

Below was announced in October 2023 and the 16 channel amp prototype appears in amp software release notes from a few months ago. The configuration software for my amp also has provisions for up to 32 dsp channels so it looks like universal code has been developed when I go into the config files for my amp. But also remember that they supply automotive OEM solutions for the automotive industry and pro audio, not just aftermarket car audio.

Mobridge were showing a 16 channel prototype at the SEMA show last year.

They have also partnered with Morel so have some combine products coming soon.

That's for an AVB based amplifier, which is a different audio transport than the MOST bus used in previous generation BMW HK systems. Maybe this new AVB amp shows promise for new generation BMW systems?

It seems to me that while the MOST bus offered a lot of advantages for car audio, it's adoption by car manufacturers was limited only to the highest end audio system options in a limited timespan, hence the few choices for interfacing directly to the fiber optic bus for audio. None of the new generation BMW's use the MOST fiber bus for audio. I'm grateful that mObridge came out with the K2 8.1.1, however any manufacturer of aftermarket enhancements needs to look at market potential and where the car manufacturers are going with their audio systems, I suspect that choices that work directly with the MOST bus will continue to be very limited if they are going to make a return on their R&D investment.

Unless mObridge specifically mentions a MOST based amplifier with more channels or capability, I'd assume that any future announcements will support newer generation interfaces, not older ones that are unfortunately no longer being used in newer vehicles. That is not to say that maybe mObridge has something coming to complement the K2 8.1.1.

Their collaboration with Morel looks to be a very promising development, I was very impressed with the Hybrid 402's that I installed in my F30, hopefully when the weather gets warmer, I'll be installing them in my F36.

I think that if you want that kind of audio system upgrade, you'll be looking at a component level system with separate MOST converter, DSP, and a multichannel audio system, not an all in one DSP amplifier like the K2. A fun project nonetheless.

[NealfromNZ]

I personally think if there is market demand it could be built.

They cover OEM & retail solutions for MOST 25 -150 solutions and a2b already in their dsp and 8.1.1 product sets. No doubt Ethernet based solutions opens up a wider market but conversely adding a 16 channel option Most and A2B front ends would make sense.

16 channels would nicely cover BMW E & F series speaker configurations with the ability to run every tweeter, mid bass & woofer active like B&O did for 9 speaker positions . Likey to suit other 2005 - 2018 euros as well as many used Most 25 / 50 /150 infotainment digital media bus.

Anyway , speculation on my behalf.

Pitty I can’t demo my system to anyone on here ( unless anyone is visiting New Zealand ) Sound quality and results achieved with DSP and OEM integration is second to none.

Nice front image that sits above the dash with excellent width backed up by excellent sub bass on tap that the OEM system just can’t do.

Is the match up 10DSP best for a H/k system in a 2018 f36?

The 10DSP from Match is a fantastic DSP amp, but you would need a MOST interface/adapter to convert audio from the BMW head unit to a signal that the 10DSP will accept. At that point you wonder if it might be better to get a Helix DSP/Amp combo that would offer more flexibility with a multichannel MOST adapter?

The mObridge K2 8.1.1 is a very attractive option for HK systems because it integrates this all in one box!

Well, it depends on how you define "all drivers"....
The HK speaker system wired from the factory uses passive crossovers between woofers and tweeters, so essentially in a F36 HK system, you have the following output channels from the factory amp:
1 Front Left (LF & HF with passive crossover)
2 Front Right (LF & HF with passive crossover)
3 Front Center (LF & HF with passive crossover)
4 Underseat Woofer Left
5 Underseat Woofer Right
6 Rear Left (LF & HF with passive crossover)
7 Rear Right (LF & HF with passive crossover)

So if you want to actively crossover any of the 2 way door speakers, not only do you need two more amplifier channels with related processing, you will also need to pull the wiring into the door for the extra speaker connections.

The Match UP 10DSP has 10 amplifier channels, making it very feasible to have the 3 front speaker systems with separate processing/active crossovers for the LF & HF if you pull the extra custom wiring. I've given this some serious thought for my system...is it worth the extra effort? I'm still undecided. I'm sure my Morel Hybrid 402's would work rather well with active crossovers! Then I have to consider how I convert the MOST signal to get an input into the MATCH UP 10DSP, there are plenty of converters out there. Hope you find this helpful.

With Mobridge for augmented HK system you can do the following

Run all HK speakers passive

Or

Drop either centre channel or rear door speakers and run a trunk sub.

Or what I’ve done.

Note , I’m quite oldschool with music so prefer the sound infront, No centre speaker and minimal sound from rear.

Active front door speakers (75 rms / 150 watts )
Underseat woofers ( 150rms / 300 watts )
Passive rear doors ( 75rms / 150 watts
Trunk sub ( 400 rms / 800 watt )

I’ve set the dsp up in the following manner.

DSP map 1 ( surround setting ON on Idrive ) map for all passenger

DSP map 2 ( surround setting OFF on Idrive ) drives seat tune , front speaker bias

Audio routing

Music sinks ( stereo on BMW ) , all speakers

Voice calls sinks , Front speakers

Nav / voice commands / chime sinks Drivers side speakers

PDC sinks , factory surround

Factory control of fader and HK eq functions
