Upgrading HK speakers is great: Ok, but what are you listening to?
Been researching upgrades for the Harman Kardon system in my 2018 540i. The stock HK system is garbage, imo. ...that, or the system is really unfriendly to rock/metal.
It seems like I can get ok bass and ok highs but the mids are absolutely terrible, no matter what adjustments I make in the EQ. Muffled and tinny at the same time, somehow. In researching system upgrades (which, atm seems to be only speakers, as no one is making an amp replacement?) everyone says the Bimmertech and BAV speakers are much better. ...but I don't think that tells the whole story. If you're listening to pop, hip hop, etc (lots of bass but not much in that distorted lead guitar spectrum), the sound dynamics are wayyyyy different. So, can anyone who has done Bimmertech or BAV speaker replacements (or even the Ali Express Bowers & Wilkens knockoffs) AND listens to rock/metal chime in on their experiences? |

Metal listener here, and avid hifi nerd.
I can say, and I was surprised by this, that the weakest link to address first is the factory DSP amplifier. The factory sound profile does way more harm to the SQ than the speakers! |

I have a 2020 with the separate RAM for the underseat woofers. Using a technics PnP harness added a 4 channel amp power the underseat woofers and a subwoofer in the boot. There is a thread on adding subs. With the rear seats up the bass is damped but the system is much better with some eq tweaks and amp/sub. Not perfect and you have to turn it up, but it’s listenable now with bass and more midrange (the underseats are more mids than woofers). My wife’s Macan with Bose shits on it.
I listen to hard rock/metal. |

I'm going to code in the B&W option and see what that gets me. I just haven't bought Bimmercode yet. |

Also, I have HU_NBT_EVO, not HU_MGU. So, I don't have the B&W option. |

Gents,
IMHO (provided good quality recordings are played) the most important things in car stereo are the speakers. The second most important is the amp with DSP. Speakers is where the most distortion happens, hence they need to be good. DSP needs to be well tuned to compensate for different distance of individual speakers to the listening position plus compensate for the cars sound properties (upholstery, etc.). If you have this, even HU_NBT_EVO head unit plays fantastic. No need for HK (I can not compare to the BW as I have not listened to it) at all. |

I did a bimmertech alpha one speaker replacement and was happy with the results. Only thing I haven't done yet is the amp. I have alot of bass heavy music.

You can only get an amp if you have LCI/ID7. ...for now, anyway. Bimmertech is supposed going to have something for the pr-CLI/ID6 folks this fall.
From a Bimmertech YT video comment thread... @colbyscott9822 7 days ago Why has everyone skipped the ID6 g30 generation? @maciejstalmach2252 3 days ago If you have an ID6 HK G30 - we're going to have something for you once fall comes around. It's going to be uuuuuge as Orange man says. Shoes will fall off so hang tight. @colbyscott9822 3 days ago @maciejstalmach2252 is it something I can buy the Alpha One speakers for now, and add the new hotness (assuming it's an amp and/or DSP) later? @maciejstalmach2252 3 days ago @colbyscott9822 Couldn't have said it any better myself. This thing coming has been in the works for years. @colbyscott9822 3 days ago @maciejstalmach2252 the website says to use 2ohm subs with your amps. Assuming this will likely be true on the new one, I'll wait until it's released to make sure the speakers are matched to the amp. The current configurator for my car specs 7ohm subs, by default. Guessing that's because there is currently no amp option, and the HK system uses higher impedance subs. |

Correct, for pre ID7 you would want SDMI25 (or Mobridge DA), MATCH PP-BMW 1.9HK+SDMI and the UP 10DSP amp. Been available for quite some time now.

They are putting together the same thing, as a package. Cost will be very similar. The only way around needing a DA is to code down to 676 and do some rewiring.
