Subject: RE : # OF HARMON KARDON SPEAKERS comment

In the BMW fast facts book 1996/1997 in reference to new HARMAN KARDON audio system. (optional 318i/328i Sedans, 318is/328is Coupes& M3) BMW is offering a new Harman Kardon amplifier/speaker system in the 4-door Sedan and 2-door Coupe models.

The Harman Kardon system employs the same new in-dash unit as the standard system; its 10 speakers are all upgraded from the standard ones and include-

  14-mm soft dome tweeter in each front door
  65-mm midrange in each front door, with Harman Kardon logo
  140-mm woofer, with dual voice coils for phone use, in each front side
         panel(ahead of door, under the dash)

  Two 65-mm midrange/tweeters in the rear shelf.
  Two 160 x 230-mm (approx. 6 x 9-in) woofers in the rear shelf.

Amplification is eight channels at 40 watts each, for a total of 320 watts of audio power - which should satisfy the audiophiles among our customers! Other premium features include:
Parametric equalizer bands and individual high- or low- pass filters for each channel
Split-band auto distortion limiting
Spatial- enhancement circuitry
Full protection against adverse condition including thermal, over-voltage or short circuit

I think the system sounds nice. Maybe its because I'm driving it with a SONY model CDX-C610 CD head unit. For example; MADONAS Imaculate Collection CD, which has excessive bass, sounds extremely clean to me.

Eight channels = Bi-amped front & rear, left and right, lows & highs.
