Have you heard the base system? I just drove an emira with the base system on this thursday. The base system is absolutely rubbish and I am by no means an audiophile…
More details for KEF Audio

So true. I had a HK system in my BMW and used Bimmercode to change the audio system processing and it indeed made a noticeable difference in sound quality. I think it would be easy for a software update to change the sound of the KEF system. Night and day, probably not, but noticeable improvement, I would say yes.
Do you have some kind of software release version of that fix? I would like to ask my Lotus dealer if my car already is up to date or if there‘s room for improvement on my KEF system.
Thank you!

confirm it still occasionally 'pops' when opening door
Don't know if true but it seems it happens more often if there is a large temp difference between when you shut off the car and when you next start it. like if you come home on a warmer day and then start it the next morning when the temp have dropped quite a bit in the garage.
I tried it today with the windows down, it definitely increased the bass level when I opened the windows and sounded surprisingly good.Have you tried using the stereo with the windows down? That's when it shows its true colors (brown).
I just got my car back today, and while I didn't specifically receive an Audio update (only ECU, TCU, and emissions recall updates), my audio quality did sound noticeably improved on the drive home.
Less distortion in the upper-midrange and lower treble area, and bass feels a bit more solid as well. It used to sound really flabby/loose, especially with the windows down, but it's a lot tighter now.

No specific update number but the internal EQ definitely have been changed. The treble have more of a presence and have more detail. the peak in the high/med range that was in the older frequency response curve ( which makes some instrument sound a bit harsh) posted in the forum have been smoothed out. The bass is a bit puncher/tighter where it can get a bit mushy/muddy before.

I reckon mine has gone backwards again since the big improvement made by the audio update. I opened the windows today as the sun was out for the first time in what seems like 2 months in the UK here and the bass sh@t itself again.
Is there something weird in the software where it re-learns / defaults to cr@pness again.
It is SO SO weird. I have reached out to KEF and have said to both them and Lotus that I am happy for them to have my car to use as a guinea pig but no response.
do I need to go in for an audtio update like every time I use the bl@@dy car??!
Getting a bit hacked off now.

Will this software update to the audio even affect an aftermarket system?
I had everything ripped out and replaced with a full Audison system which was then properly tuned and setup.
Since this latest software update was carried out, it seems to have messed it up slightly - one of the speakers now pops and it doesn’t sound quite the same - can Lotus’ latest update mess with an aftermarket system? If they changed the crossover settings, would that ripple through even though mine has Audison amp etc?

I just got a 2026 Emira with the KEF system, and it sounds surprisingly good. I had tempered my expectations based on the reviews here, but it's a really solid system for car audio. I'm guessing the 2026 model year already come pre-configured with the audio software update or else they did some fine tuning.
I'm still waiting on my 2026 Emira, but from what I've read, they finally added tweeters to the A-pillars and they also bumped up the amp power.
Yep, if your Audison system was tuned to match the EQ of the previous KEF system output, and the software update changes the EQ/timing/phase of the speakers, then your Audison system needs to be recalibrated to learn the new system configuration. Otherwise it's applying processing and corrections that are no longer valid.
Has this made any increase in volume level??? I've put a bluetooth booster on my mobile n that increase the volume output.....
maybe a little bit but it's minor and it also maybe that the i4 is quieter so I don't have to run the volume at the same level.

I just picked my car up from getting its first annual service. All software updates were performed, and I can tell you that there's quite a bit of improvement to the KEF system. Having said that, it's still a bad system overall, but it does sound better than before the update for what it's worth.
