Hi,
I just got my E89 with HiFi Professional DSP. I have had this system in a lot of BMWs earlier and just love the sound. Now I got this 2009 E89 and Im really disapointed. There way to much bass and some tones sounds like the bass is wrenged (dont know a better word for it in english:-)). I sounds like I have turned on the bass to the max and turned on super loudness. I have reset all settings in the car with no result. I have also turned down the bass and the low frequences in the equalizer, and it gets better but its still to much.

Is this the way theres cars are or is there anyting wrong with my system? The problem is there with FM radio, CD and Iphone interface..
 
Very odd.

Have you got any diagnostic software?

If so, you could drive each speaker channel, sub, mid, etc, to make sure they are all working?
 
Before I bought the car I went to a BMW worshop that scanned the car and there was no errors.

Is there a software I can buy to test each speaker individualy?

To be honest. It almost sounds like one or two of the sub's is out of phase.

I really hope that theres something wrong here thatcsn be fixed. DSP should sound better.
 
Hmm..
Im not getting any closer to a solution here. Is there anyone here that has the E89 with HiFi Proff? How does youre car sound like? I have allways been a fan of the HiFi proff in BMW, but now Im really disapointed. The spound is hard and the base is out of controll. There some kind of resonanse aswell thats really anoying. Lower base tunes sounds like they are breaking the car apart..

My BMW dealer hasnt got any solution either..
 
Anyone near you with the same setup, you could compare theirs with yours? It might actually be working 'properly' (even if you don't like it) in which case you're into an aftermarket upgrade.
 
A1GSS: Yeah, probably a dealer in the area has got a similar car. I this small tiny country there not a lot of these cars, but I could give it a try..
 
Cant find a similar car.. After playing a lot of songs, this is what I notice:

- its in a guite small range the subs in the back really are too load.
- the new song "Black widow" is the optimal to make my car sound like crap
- I belive that I can hear a noice from the subs at low volume aswell
- The subs appear to be out of faze. Could someone mixed +/-? Perhaps a resonance can make it appear as out of faze?

Any thoughts?
 
I have now investigated this some more. It seems like when I pull the fader all the way to the rear, the bass sounds greit. With the fader in the middle or in the front the crappy sound appears.
Once again, it seems like its out of face. Even at really low volumes..
 
Puh! Finaly i solved this problem. After 7 hours in the garage:-)

This is what I did:

- opend up the interior and got the subs out.
- covered every inch of metal, where the subs fit, with asphalt damping.
- added dampingwool under the subs
- last but not least, I got an older Y cable from BMW (that one for the old Iphone plug), added an adapter to Iphone 5+ and the sound in now prefect.

Theres a totaly different sound and feel in the car! Even outside theres now noises what so ever.

Im really really pleased.

Now I just need to sell the Earthquake SWS 8Xi speakers witch are 2 OHM and factory is 8 OHM..

Thanks for all help! I got a lot of pictures during the job, so just PM me for any questions.
