screenie from my order sheet

It will. Much richer and smoother. Much more detailed. Less distortion at higher volume levels will be achieved!

Thank you :)

And Nokia in the older cars :(

And yes we do ship down under! Wish I had a planned trip to visit and I could deliver :(

I thought it was Logic7 :) Thanks for the "screenie"

More Detailed Info:

The big issues with the stock system (I'm going to refer to the Logic7 system since that's what most of you have) are as follows:

VERY "choppy," non-linear midrange response
The factory midrange drivers do not have a curvilinear cone surface and are aluminum cones. Furthermore, they are being run full-range from 150Hz or so and up, leading to VERY, non-linear frequency response, especially in the midrange frequency band. There's what's called a lot of breakup.

Our midrange drivers instead use a fiberglass cone and a curvilinear cone surface. This means that you get most of the rigidity advantages of aluminum (excellent transient response), but MUCH smoother, more linear frequency response in the upper midrange.

In addition, we run the midrange drivers using a low-pass crossover, insuring that they never operate in a frequency range that's not ideal. We can do this because our tweeter plays much lower than the factory tweeter can, again giving smoother, more natural sound (more on this later).

For those of you for whom the above sounds like gobbledy-gook, basically the gist is this: right now, if you listen to your music carefully, you'll notice there's a harshness and "choppiness" to the way it sounds, especially voices, guitars, anything that falls in the midrange band. This is because of the way the stock speakers are designed. Our new speakers "smooth out" all of those frequencies so that individual sounds and instruments are more defined and detailed at all volumes, and listening to the system at higher volumes isn't so tiring.

Our tweeters have a MUCH bigger frequency response range.
The factory tweeters are aluminum, too. BMW (or HK) set them up to play from about 4Khz and up, meaning that most midrange is coming from the midbass drivers and is terribly broken up by that point due to their poor design (not to mention there's a big overlap above that where the midranges are playing into the same range the tweeters are). And, because the tweeters are aluminum, you have the same "tinny" and harsh sound that you get with the midranges.

Furthermore, they only play up to about 12Khz, leaving a whole range from 12Khz to 16Khz of music more or less completely out of the picture. This makes the car sound sort of simultaneously harsh and muted. Very weird combination.

Anyway, with our tweeters, they'll play from around 2Khz and up (WITHOUT overlapping with the midrange drivers) and actually reach 16Hkz. This does a few key things:

- You get much better imaging. By "moving" the sound that was coming from the midranges up to where the tweeters are playing, you are effectively "raising" the soundstage to a higher plane. So if you close your eyes, the musician seems like he/she is at eye level instead of your waist. This creates a much more realistic listening experience.

- You get much smoother midrange response. Because we're not asking a driver that should ideally be producing some midbass and lower midrange frequencies to reproduce our most critical frequency response, upper midrange, and instead having our tweeter do it, we get a much more natural, linear frequency response.

- You can actually hear music from 12Khz to 16Khz! There's a lot going on up there that we're just flat out missing from the stock system. With our tweeters, because they can play much higher, you get to hear the subtle upper frequency parts of the recording. This leads to a "livelier" sound.

- You get much more realistic sound reproduction. Our tweeters just sound better. They're silk, not aluminum, giving them a warmer, richer sound. The difference is night and day, like listening to an acoustic guitar made of coke cans vs. one made of the finest wood.

Overall, the big advantages of our Stage 1 are MUCH, MUCH more smooth, accurate frequency response (even-ness of volume of all sounds), and a more natural, clean, warm sound.

Hope that helps answer your questions!

MMM .. that seems an old definition.. anyway it's a DSP system with 16 speakers... It does not I believe have any brand such as Harmon Kardon / Mark Levison (Lexus)..and as such is not Logic7 which is a HK label.

I thought logic7 was a Lexicon audio processor, hk just use it - like bmw

Yep you are right.. the E70 catalogues do not use Logic7 wording .. could well be Logic7.. pity about the speakers, I'll be getting the BSW upgrade when it comes out ..!

Could you please provide a breakdown of what the upgrade consists of? Such as 2 tweeters, 2 6" for rear, ...?

Thanks!

Sorry for hijacking the thread started by a BSW guy. I think replacing the drivers alone in the basic system wont solve all the issues if there is no proper amp installed.
For those who paid extra for the Logic7 option (or Premium hifi if you like), the replacement could deliver much better sound, as that system at least has amp and DSP vs basic audio. It is still beyond me why to use 16 speakers...? Maybe for listening to 5.1 surround while watching DVD.

Anyways, I just have thrown away all the crap that BMW has built in the car as for drivers (mine was basic audio) and had a Morel Elate 6" 3-way component system built in for the front stage. It is powered by a DLS Ultimate dual mono amp (nicely fits in the space that BMW saved for me by using the stupid run flats and giving no spare wheel). I had the installer to remove the rear door speakers not to mess up the sound.
This sound is "orchestrated" by a Rockford Fosgate 3sixty.2 DSP (settings beyond imagination - controlled from laptop or Palm). It is necessary as the head unit cannot be replaced for obvious reasons - to get acceptable sound for the amp and the speakers.
Some sound dampening material also added here and there.

Result? It is another world....

Unfortunately the subs are not placed in the best location under the seats and the space there allows no bigger subs than 6,5" - I still have some nice basses, yet my side mirror is not shaking.

All the system is stealth - one cant see it, just hear.

Highly recommended. It was cheaper (along with the installation), than the OEM Premium hifi. :thumbup:

i thought the stock system comes with a 205watt amp?? along w/14 speakers and two subs!!

205 was more than enough back in the days... it doesn't sound bad upgrading the speakers... just now sure if it will be a day vs night difference.. wish i could test them out!

$1850 for upgrading the system is alot... and so is the extra work you described just to save a few bucks!! i dont' really like the idea of people messing around with the wiring, dash, etc..

easier to swap speakers and leave everything else alone..

not sure what's stock in the US but in australia there's two extra options over stock sound - one is a 12-speaker AUD$1200 option which has a 205 watt amp (standard on V8 here) and a 16-speaker AUD$2700 option (logic 7) which has a 600 watt amp. I don't know how many watts the stock amp has or how many speakers you get
