Has Anyone Only Replaced The Speakers On The HK Stereo?

I have a pre March 05 Cooper S, with the HK stereo in it, I really do not like the tweeters they put in front of those little mids in the top of the doors, has anyone just replaced the mid+tweeter in the door with something else? As far as I know the factory amp drives each pair of mid/tweet with a dedicated amp channel, is this correct? Do you know what the cross over freq is? Thanks..

The factory speakers are 2-ohm setups, so you may be limited in your choice of aftermarket speakers unless you're willing to take a big power hit from replacing 2-ohm speakers with 4-ohm speakers.

I don't know if the each tweeter/mid combo is driven by a single amp channel, or if the tweeter and mid each have their own channel. As for the crossover frequency, the factory crossover is probably just a capacitor wired across the tweeter terminals - I can't see them springing the bucks for a more-sophisticated one. If you can find the capacitor, you can calculate the crossover frequency.

I was all ready to swap mine out when I first got the car.

Then I read that a badly adjust HK would sound terrible.

So I set it all flat and chose one of the spacial settings (Electronic) and turned on *Driver.

Odd really that badly adjusted appears to mean 'adjusted in any way away from that setting'

I have not adjusted it in two years, nor even felt as though I need to replace any aspect of the system in any way, despite being a music snob.

For reference I rode in an MCS with the HK system and aftermarket speakers - the owner have used Kenwood speakers and custom attenuation to restore the balance - I did have the model numbers on a scrap of paper somewhere, but cannot find it. It sounded OK, but considering that there was about $1000 invested in getting it 'right' it certainly did not sound that much better than 'unadjusted',

Don't worry, this is the audio-related section. You got it right the first time... after all, it's "Navigation & Audio", right?

Interesting... when I had my H/K, I always preferred the "mini h/k" DSP setting. I believe it's supposed to be the one tuned especially for the MINI, yet closest matches the original recording in how it sounds. Treble & Bass set to dead center, mini h/k mode, and driver mode OFF (because I wanted equity for my passengers!).

In any case, I'm happy that you found some settings that worked for you. In some ways, I am happy that there are are only two DSP settings for the DPSM - "off" and "on", because it means I won't have to wrestle with too many choices!

I must check it when I leave the office - I am pretty sure that is what it is set to - I rarely have a passenger and if I do the music tends to be fairly quiet so I did not worry about equality.

Doh! Silly me, I just copied the entire message from mini2, where I first posted :< ... Edit time...

Also, it does not seem to matter WHAT I set the settings to, the highs just always start to hurt after a while... but then again, I have always been somewhat sensitive to highs (actually was barely able to hear dog whistles when I was little, and burger alarms... nifty, eh?)

Ahh, 2ohm, that helps! Yes, I know there is/I seem to remember, there being a simple cap between the mid and tweet, but I mean on the crossover for the low side of that tiny mid.... so, 1 amp channel (with high pass active filter), driving the mid+tweet, with a cap to keep the tweet from pop'ing.... I am sure the mid mechanically rolls off, but all in all, not the best way to do things, I was hoping I could just swap out the mid+tweet for a tweet that can play low enough, like the Morel tweets, they go down to 1.4k!

Ok, went out to the car and switched it from "natural" to Mini HK, and it has allot more punch, appears that are bumping up the midbass, and using the front's and rears equal amounts of bass, but I did notice it appears to have "space" to the top end, maybe a little reverb? Well, it definately does not sound as flat, but I guess I should experiement... would love to try some different speakers still!

Yep...
  • DSP set to "mini h/k"
  • Treble and Bass set to dead center
  • Driver mode OFF
Worked great for me. I was very content with the system until I heard the DPSM.

Have you read this MINI Harman/Kardon review? A definite must read for every H/K owner.

Had the DPSM never come to the USA (or had I never heard it myself), I probably would have kept the H/K just as it is. It's a very good quality system, it just isn't particularly "loud" when you want it to be, that's all.

BTW, I merged the two posts you made in quick succession, back-to-back, for easier reading. Are you not familiar with multiquoting? It's a wonderful feature of vBulletin!

Ok, so mine is configured as yours at the moment... I'll use it for a while, see how it does.... Plenty loud enough for me.... DPSM?

Multi-quoting? Hmm... How do you quote two people like that? Just hit quote, copy the text, cancel, and go quote the other message, while pasting in the other quote?

LOL... don't get me started on DPSM. Unfortunately, unless you are absolutely crazy like me, it won't apply to you... Here, look at my thread on it - just read my first post (and look at the links I include in it) to get a general idea.

No, much easier than that. I gave you a link to my little tutorial on it in my last post. Here it is again --> Multiquoting.

Note that 'Driver' mode is only active when there are no passengers (sensed by the seatbelts, maybe?), at least per the documentation.

That's interesting, I've never heard that. Worth testing, and easy to do. Just have a passenger sit in the car with you, and see if turning Driver mode on and off seems to make any difference in how it sounds. If what you say (read) is true, it shouldn't!
