What is Logic7?

Logic7 is BMW's optional professional HiFi stereo system which is an enormous upgrade to the standard stereo. Logic7 is a special digital audio signal processing mode for two-channel stereo signals and multi-channel multimedia signals. The objective of Logic7 is to create an experience in sound as true to the original as possible for all listeners within the car. The Logic7 system is comprised of four tweeters in the mirror triangles and in the parcel shelf, one 100 mm conical subwoofer serving as the central loudspeaker in the middle of the instrument cluster, four 100 mm conical subwoofers in the doors, two 100 mm conical subwooders in the parcel shelf, and two 210 mm central base loudspeakers beneath the front seats. A total of 13 speakers.

It's the best sound system I've ever had in a car!

I'm curious how it is compared to a Mark Levinson audiosystem in a Lexus. I heard that once and it sounded awesome. I was very impressed. My hope is that the logic7 in my new car will sound something like that!

100mm=about 4 inches. These are the mid-range speakers.

Found some info:

Very interesting find and nice write up!

Additional information on how Logic7 works can be found in the BMW Technology Guide.

Look here ... :wow:

Perhaps this was already extensively discussed, and if so I'm sorry. I didn't get a good hit in search. Is it possible to add Logic 7 after delivery? The simple answer is probably no, but are there ways of swapping the stereo out?

I do not have Nav. I do have Sirius and it sounds awesome. :winkcool:

Regret for not getting the Logic7. ARGGHH! :angry:

Is the Logic7 that much better? Is it worth $1800 bucks??? What I absolutely hate is the placement of the changer - deep inside the glove box. You CAN'T swap it/load it or do anything from the driver's side. You pretty much have to be out of the car or contort yourself on the passenger side to insert the cassette. Why can't it be on the dash like on the 7er?

Also, a car is about one of the worst listening environments there are with the road noise and all the other "noise generators" in a driving environment. Why would one buy a surround sound system that costs that much and put it in a car?

How about after-market systems - is that a viable option? Is there something comparable - with the cassette elsewhere - that can be retrofitted? I know, a cassette in the trunk is inaccessible from the driver's side, but....

Can someone convince me that the Logic7 is the way to go? I mean, it's the ONLY option other than the standard stereo and the one-disk-at-a-time load on the dash. Is the standard stereo that bad? Is it bad at all? Is it acceptable?

Thanks!

Santiago.

Many of your questions do not yield clear, "yes or no" answers since discussing sound systems is a subjective topic that relies heavily on individual opinions.

Rudy, I appreciate the links. I'll think about it. Hopefully I'll be able to test drive a car with it. You're right, I'll either like it or not care to pay that much for it. It's all subjective and I see most of you out there love it - but $1800 for a CD changer??? What else does it do?

About the pictures of your car. White is beautiful and it only cements the notion in my head that a light colored E60 shows off so much better than a dark one. There are many posts about color choices and as I commented one day, I was almost all set in ordering a blue (of some kind) or black until I saw two E60s, parked one behind the other on the street and I could see both from the side. One was black and the other silver - don't know which silver - and the silver showed so much more detail and contrast. The black one was beautiful as well, but it appeared as a single, fat, black mass without much definition. The silver on the other hand was so defined - the windows, the wheels/tires, the shark antenna, the satin trim (which is totally lost on the the dark-colored cars), etc. The silver car also looked longer and lower. The E60 looks fat in a dark color. I just have to see what interior/trim colors are "allowed" with silver so I can make up my mind.

I think I'll get one of the silver colors when the 550i comes out. I'm holding out for the 6 speed and here in Germany I can order all kinds of goodies right off the showroom.

Anyway, I'll seriously consider the Logic7, but is there an after-market alternative?

Regards,

S.

Thanks for the kind words about my car and color choice. Obviously, I agree! ;)

In a couple of the links I gave you earlier, there were some posts from people who did a custom audio install on their cars. Merzbow is one member who did something custom but I can't remember the names of other members who took the plunge.

Hopefully, someone else can chime in to remind us who did an aftermarket install (or you could search the forum database, etc.).

Good luck!

You have to experience it yourself!

There is a good oportunity in September: IAA.
We have a little E60.net meet & greet and go to the Ring afterwards for a couple laps. You will be able to see all different options and the performance of the different engines... ;)

ICEMAN, tell me about the meet and greet at the IAA. I've been patiently waiting since 2003 for this year's show. I'm VERY interested about seeing all the different cars and options and stuff as you mention. Keep me up on it please. It's just around the corner in September. I may take a day off and go during the week as the weekends are a zoo.

I'm in Darmstadt, where are you? You can PM me if you wish. I am dealing with Pentagon Car Sales for my car's order.

Thanks!

As everyone says - the choice is subjecive - but I have test driven a 5 with the Logic7 and does sound fantastic.
I turned it way up to the point where you couldn't really listen any more and there was no distortion. Just pure sound. Not that I generally have it at such volumes, but it's nice to see how a system copes at high sound levels. The degree of clarity there is a good indicator as to the quality of the setup and with Logic7 it is still crystal clear.
The bass is also very well judged. I hate massive, thumping, unsubtle bass, Logic7 seemed just right.
I'm sure it can be set to head banging levels, but I didn't have time to get into that level of detail. Besides, I was having too much fun driving the car (fully loaded 535d).

I have always upgraded the stereo in my cars - not to silly levels - just putting in some decent Alpine stuff usually. But Logic7 blows all those out of the water, although it does cost about 3x what I normally spend.

I reckon it's worth it though, in a car of this quality.

I have also listened (less extensively) to the "normal" hi-fi upgrade (in an M5). Not bad at all, but not in the same league as Logic7 imho.

Standard setup, for a similarly short time, was OK. If you didn't know any better it would be fine, but......I'd already been seduced, and I'm a sucker for good sounds :)

Just my 2cw

how do i know if a car has logic 7? I am looking in to a 530i individual and its a 2005 May production, does it say anywhere its logic 7?

It should be noted that owners of the LCI (facelift) models who owned (or heard) pre-LCI cars with Logic 7 have reported a vast degredation in sound quality in the Logic 7 of facelift models. One forum member has fitted new door and parcel shelf speakers, noting an improvement. In some markets (such as the UK), BMW now offer the "BMW Individual Audio" option which is more expensive than the Logic 7 and replaces it as the best audio option for the car. I am sure this FAQ will be updated at some point to include further information, but thought this may be useful for people browsing the FAQs...

Have to experience it, and then your going to want it. Highly reccommended as a factory fitted.

Logic 7 + iPOD + Original Theme music for Superman movie .

This will help you decide .

:cool:

I'd have to give a :thumbsup: on the logic 7 system, I just wish BMW chose XM vs sirius.
Btw..where does an ipod plug in??

depends on if you like listening to your music with full on surround sound. I know I sure do!

I find it illogical that i did not get the L7... (corny but true)

I went from a 2004 e46 normal stock sound system (okay but not great), to a 2006 lexus is250 (Don't know what I was thinking!) WITH Mark Levison upgrade which was the best sound system I've ever experienced till.....I'm back in a BMW, 545i with Logic 7 and I have to say it's a small price to pay for the upgrade in sound system and it's very compariable with the Mark Levison in the Lexus which is...I hate to say it but considered often as a baseline for comparing stock car audio systems.

BTW in Australia the Logic 7 upgrade is $1800 for BMW, but for Lexus the Mark Levison upgrade is $5500!!!

In summary, my opinion is get the logic 7 upgrade as it's far better than stock, unless you're going for an aftermarket setup.

Its what our government doesn't have.

My 07 550i has the L7. Holy crap is all I can say. I have never heard a factory system sound so clean and LOUD at the same time. It's amazing.

I would not have paid the $1800 for it, but the original owner did and I am sure glad about that.

Some guys listen to music in their cars. I listen to my wife complain about my driving (we carpool every day). :lol:

+1 Don't know that I would have paid for it as well, if I were the original owner, but I am damn glad I have it. Clean and crisp with choice of concert hall and theatre for surround settings.

hi...just purchased a 08 550..how do i tell what sound system i have?....i didn't ask the dealer

It was a must have option for me.

I wanna know how you can tell if you have the logic7 my music sounds insane for a stock system but would like to know which system I have ? Like to see my options

have your dealer or a dealer look up your vehicle via VIN...they can print out a list of all your options...

I believe the option code is 677- premium hi-fi system

Or you can just look in the iDrive under settings, audio, if you have an equalizer and the surround sound settings, you have L7. If not, you have HiFi system.

Or look at the rear doors. Logic7 has one speaker in each rear door for a total of 13.

how can I tell which system I have in an 2004 525i? I have a aux plug and 6 disk changer in the glove box if that makes any difference whatsoever lol

Plug your VIN into a decoder such as this: BMW VIN Decoder - By Mitsuhiko Kanekatsu and it should tell you. Also count your speakers. There are 11 with the Logic7 system.
