I am familiar with the KEF brand and their audiophile speakers over 40 -50 years. I am thrilled by the fact that the Emira will be he first car model to feature this brand’s coaxial speakers in a car stereo system.

However, except for a brief demo of the Emira’s car stereo system at my Lotus dealer with preset music material (not of my choice, and of unknown bitrate and quality level), it did not enthuse me at all. I far prefer the Harman Kardon car stereos in my 2008 and 2013 BMW 3-series cars).

Anyhow, except for the KEF speakers, the rest of the system (the electronics) come from a more “generic” source, and it is unknown who did the overall “design coordination” of this audio system. The power amp is said to be branded Harman Kardon (DCY11), but the Harman Kardon brand itself has been sold off a few times, and the design of new products are farmed out to subcontractors, so there is no guarantee of a particular sound or quality, and possibly little consistency between individual products.

The subwoofer in the Emira is an Australian design called The Fresh Air Speaker, and the characteristic is that it does not have a dedicated enclosure to itself, but it is mounted internally into the Emira in a way that it uses the cavity of the Emira itself as the enclosure. This will definitely mean that it will sound and work differently depending on whether the side windows are open or closed. I would definitely prefer a subwoofer with a clearly defined enclosure, even though it has to be a small one, and that the bass frequencies will be limited by the size of the enclosure.

Soon a few friends in Japan will take delivery of their Emira V6 FE, and I may have more chance to listen and test. However, so far my overall impression from reading others impressions on this forum is that the sound quality of the Emira’s KEF audio is “so-so”, and that you have better focus on listening to the exhaust and supercharger (In the V6 FE), and that the Emira as sportscar has other attractions than audio quality.

After I get my own car, this is obviously an area that I will explore and work on. I may for example switch to another subwoofer. I have a particular German brand in mind. I do believe the KEF speakers themselves will work well, and I will look for ways to enhance the core of the audio system and the power supply to the system.
Thanks so much for the information! The HK system in my current 2019 BMW is very decent but still nothing compared to the B&O I had in my old 2008 Audi. I was hoping that the KEF would fit somewhere between the 2. Anyway you're right, I doubt a fantastically good speaker system is required as the engine would be the main source of aural joy when driving.

There was a thread dedicated to the KEF speakers but I can’t find it.

The Emira is way too loud for decent audio. You’ll be able to get something that sounds good when turned up loads but never as good when compared to other quieter cars at lower volumes.

I can appreciate the fabrication work to get the larger mids into the doors properly. Watching the video; i hadn't realized the KEF's were only 3" two ways. 6.5" would have been a better move. I could pass on replacing the mids in the rear as they only need to be there for fill. As for low end; 6x9? Really?

I'm not sure these installers knows what they are talking about even if their workmanship is top notch.

After looking into it some more, the Uni-Q driver looks to be similar to the one used in the KEF LS60 speaker system. It has a 0.75" tweeter and a 4" midrange driver. The driver is not 3" as claimed in the Youtube video. Now, driver size measurement is fuzzy at best. They can vary greatly depending on the manufacturer and how the measurement is made. Some manufacturers measure all the way to the edges of the basket and others measure to the edge of the surround. It's almost the case like TV size measurements where a 65" TV's actual size can vary within the range of an inch. But for certain KEF calls this driver a 4-inch 100mm unit.

In the LS60, the Uni-Q driver is crossed over to the woofers at 400Hz. I would assume a similar crossover point for the one used in the Emira. The mid-bass drivers being behind the user is not really an issue since frequencies below 400Hz do not contribute to fore-aft localization. Humans determine fore/aft location of a sound source based on how upper frequencies above 3kHz is shaped by the outer ear. As long as the mid-bass drivers are placed outside of the listener's position and can generate phase and loudness difference, their stereo effect will work just fine.

The subwoofer is indeed a joke.

Quite funny when he says these systems are not heavy are not even as heavy as a passenger.even if it was 2/3 the weight of a 75kg passenger I wouldn’t want to add that much weight.
I’d be surprised if they get many takers on this especially with all the posts regarding weight saving on here.
