How to differentiate the different stereo options?

[tranquility]

In Canada, we have the choice of the:
1. std HiFi 11-speaker sound system, incl 2 subwoofers; or
2. optional LOGIC7 HiFi Sound System, incl 2 subwoofers.

I'm not sure if these configurations are same in other countries.

I have #2 and just like to confirm the speakers' locations/function:
-1 tweeter near side mirror
-1 mid in door
-1 mid beside seat
-1 mid beside feet
(x2, so 8 speakers here)
-2 subwoofers, 1 each behind seat
-1 mid behind/between seats
-1 mid on center of dashboard
=12 speakers total

Is this correct? If so, I guess that #1 and #2 configurations are the same except there is 1 less speaker for #1: what speaker is that?

Btw, I noticed a long time ago 'Blaupunkt' used to have its name on BMW stereos, but now it's gone. I assume that these systems are still made by Blaupunkt and just curious why the name's gone?

Thx, I saw that thread but it doesn't exactly answer my question.

The base sound system that comes standard sounds like crap.
The optional sound system is nice, but is overpriced.

These are personal opinions. Everyone's opinions will vary.

i don't know why this has to be so dificult...

could someone with a good camera take pics of the 14 speakers, someone with 11 (tranquility) and someone just highlight the 6 from the base system?

So what is the 14-speaker system called? I guess that is a better one not available in Canada?

This one has only 13, I guess it's not the same thing.

Any Canucks here w/ the LOGIC7 HiFi Sound System, incl 2 subwoofers that can verify the location and # of speakers? Thx.

In the brochure:http://crm.bmw.ca/com/en/newvehicles...ml?currPage=26, is written the system has 14 speakers.
I guess the European system is identical and is called HIFI system professional.

The speaker setup is as follows:
Doors: 2 mid range speakers + 2 tweeters.
Foot well: 2 low-mid speakers.
Center console: front 1 mid range.
Rear: 2 mid range speakers + 2 tweeters.
Center rear: 1 mid range.
Behind seats: 2 sub woofers.

The sound system has a digital audio connection with the D-Class amplifier in the trunk.

That link was for the sedans. I had an E90 and I had 13speakers.

So I do have 14 speakers instead of 12? I guess the speaker grill beside the seat actually has 2 speakers inside (I thought it only had 1).

EDIT: according to your link, the std system only has 245W while the upgrade has 650, so that's over 2.5x the power. No wonder ppl are complaining about the std stereo!

[Memphis1]

that's why I posted my link, because theres no system with 12.

The link you posted was not clear re description of the 14 speakers.

[Memphis1]

^^ so if I wouldve said there's two subwoofers on each door you would have gone crazy looking for them???

I don't understand. Anyway, all I'm saying was that your link was not clear, unlike the above poster.

Many complain about the standard system, 6 speakers and 4x50watt. The 245 watt is the HIFI speaker system with 11 speakers.

Does that mean it's 50W max or 200W?

[teagueAMX]

The way to calculate total system wattage is to specify how many watts per channel and then multiply that by the number of channels. For instance:

50w per channel x 4 channels = 200 watts total

Of course, you can have more than one speaker per channel, so they don't rate the total system max output in watts per speaker, but watts per channel.

Dont forget to differentiate between Peak, RMS and PMPO power.
Plenty of audio manufacturers try to boost their image by quoting peak or PMPO power instead of the true RMS.

I dont know but I would hope BMW sticks with the honest numbers of RMS.

And before I get asked:
RMS = Root mean square - roughly 70% of the peak power, the true average power of a sine wave output.
Peak = the maximum amplitude of the sine wave power output
PMPO = peak to peak measurement, basically twice the Peak value.

You're welcome. I'm curious, did you get a window sticker with your car? I ask because that would list your options or you should be able to get a complete lists of vehicle options from your dealer. It would be good to get the actual codes.

Now you're making go back to my old audiophile days.

As a guess, I'd say BMW will publish peak output rather than RMS.

Wrong numbers for the standard 6 speaker system, should be 4x25watt .

From the Dutch catalogue.

663 Radio BMW Professional, 4x25W vermogen,
676 HiFi actief luidsprekersysteem, 245W vermogen, 11 luidsprekers
677 HiFi System Professional luidsprekersysteem 650W, 14 luidsprekers

I assume the number is the total maximum power of the amplifier.
