Hi everyone, hope you are well….having recently taken delivery of my Z4 I was wondering if anyone else has had any issues with their speakers on their HK system? I’ve noticed that there seems to be a vibration or distorted sound when playing certain songs. I’ve played around with the settings together with the equaliser and I only have the base increased by two clicks. Any advice or suggestions would be appreciated. Thank you!
 
Hi I have the same Hk set up and haven’t had any problems with regards to distortion or vibration when listening to a queen album at 80% , I did read on another forum about the wires in the door cards vibrating
 
Many thanks for your reply Timdon. Out of interest, were you listening via a wired connection or wireless CarPlay? I’ve reduced the 500hq on the equaliser and it’s still sound’s distorted even at modest volume.
 
This was a topic on another forum and this is more or less the suggested setup to get the best out of it. It improved the sound in my car. There are certain songs mentioned to test a setup too such as Massive Attack's Unfinished Sympathy. Give both a go.

The HK speakers are very poor quality, i swapped mine out for an upgrade kit from audison, new dsp and an additional hertz subwoofer, night and day difference.

The doors and back wall need a lot of isolation to remove vibrations. I also added some soundproofing in to the bottom of the soft top box. And added some sound dampening on the trunk side ski hatch door. I still get some vibration sounds at high volume but a lot less than before :)
 
Looks like I'm not the only person who was underwhelmed by the HK system. It's not got the same depth as the one in my Mini convertible, and distortion creeps in sooner as well.

Might need to rethink my plans.
 
same here , wife just got an M40i , came from a 2014 TT which had Bose. the Bose absolutely smokes the H&K , we are both pretty disappointed in how it sounds played with eq etc and its better , but still poor . so will defo be doing some upgrades , it really lacks sub bass .
 
I found a second Z4 with a HK and it had exactly the same issues. Even at very low volumes the bass would distort, unless you dropped it right down on the EQ, so I ended up buying another Mini (JCW Convertible) instead. I’d have liked a Z4 but didn’t want to spend £40k on a car that needed stereo upgrades.
