: Does anyone know how many speakers the DSP system has? I own a '97 first production ('96) and have heard that my car has 14 speakers and then BMW switched to 12 speakers in later models. Is this true? Also, what size are the bass speakers (woofers)? A post earlier said 12"!!!!! I can't believe that a 12" sub only puts out that little bass.

You have 12 speakers. The 7 series has 14 (4 subwoofers inside the package shelf). Early advertising for the E39 sometimes used info taken from the "Top Hi-Fi" option for the 7 series - this confused lots of people.


Here is the info about numbers of speakers, etc.

There are 3 audio systems.

1. Stereo (6 speakers) this is the base system - not marketed in North America

2. HiFi (10 speakers) - this is the standard system in NA.

3. Top HiFi with DSP. (12 speakers as follows)

Front doors: (total 6 speakers)
- 5" woofer (this is upgraded from system 2 to 3)
- midrange - beside the vent
- tweeter - in triangle by the mirror.

Rear doors: (total 2 speakers
- midrange

Rear Package shelf (total 2 speakers)
- 5" woofer (same speaker as the front door but in a different enclosure)

Subwoofer.
This has 2 5" or 6" subwoofer speakers mounted on either side inside the subwoofer enclosure. I have looked at them but not measured them exactly
Each speaker is bi-directional and is powered in each direction therefore powered by 4 channels.

The sound comes out of 2 reound ports on the top of the subwoofer enclosure that is directly below 2 round openings on the bottom of the metal base for the package shelf. The sound then comes up through the package shelf chamber and out those long vents at the back window (those vents also allow air to escape from the cabin where it is vented out the car on the lower outside fenders)

Soooo - your DSP system has 12 speakers, driven by 440 watts in 14 channels ( I do not know what power each channel is).
I also do not know what power standard is used for that wattage - but I suspect it s not RMS (like my 600 watt McIntosh home amp is).
