DSP absolutely does SUCK!!!  My tiny factory subs with DSP removed and  
aftermarket amp TOTALLY BLOWS AWAY the M-Audio subs in the M5 with a stock  
system. 
 Entire range from lows to highs.  Again, ACTUAL side by side  comparison - 
my car next to an M5.  The owner of the M5 was  pissed.  He hates it when my 
car does something better than his (very  rare)!  Of course since his pockets 
are deeper, he spent enough money in  his audio upgrade knowing that I can't 
afford too.  Baby...   Also my upgrade was free.  Friend is an audio installer 
and happened  to have an amp lying around.  I was also able to sell my factory 
DSP amp to  someone who's amp had crapped out.  $$$  Efficiency in engineering  
exists in audio too!
 
My buddy who is a service writer at the dealer regularly asks me to come by  
and show my car for a listen to preferred customers before they drop a butt 
load  on an audio upgrade that would be limited by the factory DSP.  Even Rob  
Levinson with the 750 6 speed was pissed off by the factory DSP.  He didn't  
know that a relatively simple solution existed that would make his upgrade 
sound 
 WAY better until I told him about it.  Like I said, anyone in the Chicago  
area is welcome to listen.  I was going the route of a custom box etc.  until 
my audio buddy researched in detail for my car.
 
This is true of any audio system.  Before any of you guys blow a ton  of 
money on subs and new speakers, upgrade the amp first to get a purer  signal.  
Th
en you go from there.  It's amazing what you can do with  relatively simple 
upgrades AND decent stock speakers and factory sub.  Use  the same approach as 
you would for modifying your car's powertrain.  
 
Read upgrade on E38.org.  
 
_DSP  analyzed..._ (http://www.geocities.com/jyl087/dsp-analyzed.htm)   
 
There are better details somewhere on the web but I'm too lazy to look for  
you guys.  You know how to Google!
 
Like I said, I didn't have to go very far to be satisfied in the audio  
department.  Leaves more money for things like more HP!  I became  frustrated 
with 
my audio system when the Chevy Cobalt I rented in Vegas with the  factory sub 
and satellite radio made my car sound like a Yugo.  Now if a  cobalt does 
something better than your car, something is wrong!

DSP is  not all that bad. It is not bandwidth limited in the low frequencies,
the  limited factor is the tiny woofers used. The cool trick for E39's with
DSP  is to add the M-Audio subwoofers (used in the M5).  These dual 10"  subs
(with dual voice coils) replace the dual 5" Nokia subs in the bandpass  box
suspended from the rear deck.  Simple swap.  If they will fit  in the rear
deck of the E38, I would go that  route.
