Love Of Sound

Exceptional Audio Fidelity

We took your factory speakers and re-engineered our upgrade for one thing: clarity. So you can simply swap your original speakers for ours without changing anything else in your audio system, and the result is smooth, natural, yet unbelievably detailed reproduction of your favorite music.

Easy OEM Swap

Same Dimensions, Higher Quality Throughout.

We engineer our speakers with the same unique size, shape, connectors, impedance, and efficiency as your factory speakers. That means installation is as simple as unbolting your factory speakers and bolting ours in, and it's totally reversible, too. No one will ever know you've upgraded your audio system except you. Unless, of course, they hear it.

Music As Intended

Enjoy music as the artist intended.

We engineered speakers to produce higher quality sound: a wider range and more balanced reproduction of the bass and treble you are currently missing. That's because, unlike your car's factory speakers, we use proven audio technology: woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters.

BMW M3 and M4 Speaker Upgrade: What Works, What Doesn't, and Why It Matters More in an M Car

The M badge gets you a tuned suspension, a more powerful engine, and larger brakes. The speakers are whatever the factory installs in the trim level you chose.

Here's what that means and how Stage One closes the gap.

Generally when I am unable to contact someone telephonically and speak to them I fear customer service is questioned. I sent an e-mail and within less that 12 hours I received a reply that was concise, professional and informative. I was prepared to purchase and amplifier and you stated that one was not needed so it was not about the money. Your positive communication was a large part of my purchase and your product sounds amazing.

I ordered the ghost underseat subwoofers for my bmw and I was having issues with the product. The customer service team was over the top helpful with solving my issue. Great product and great service!

Front door speakers and rear deck speakers connect by sliding wires into a connector. There is no actual connector. It just sits in there and you hope for the best.

Also the wire colors don't match the OE wire harness, so you just kind of have to guess what wire goes in what hole.

So ... room to improve.
I honestly can't tell any difference between the bav sound speakers vs the OEM HK speakers.

Mini F56 - Stage One Speaker + Ghost Subwoofers

The Bavsound kit has tremendously improved the quality of the sound on my standard (non-HK) Mini F56. The sound is much crisper especially at high volumes. With the Ghost Subwoofers, the bass is much more powerful now...
The support team of Bavsound were also very helpful in walking me through the installation and answering my questions.
I definitely recommend this upgrade for F56s with standard speakers.

Good sound system now

Except for the installation of the rear side speaker that request some modifications to the seating.

Finally satisfied with the audio on my F80 M3

The OEM Harman/Kardon on the F80/30s system is quite a let down for my ears, lacking resolution especially in the low- and mid-bass frequencies. I have to say that after installing Bavsound's midrange speakers and ghost subwoofers, the difference in depth and fidelity is night and day, and is noticeable even to the untrained ear.
In my opinion the most improvement on this car is to be gained by replacing the subwoofers, and for anyone hesitant to buy both the Stage 1 and the Ghost Subwoofers, I would recommend starting with the Ghost Subwoofers alone, because the subs on the BMW go up to as much as 320 Hz, I think, and this where most gains in sound quality can be achieved. It is not even the mere volume that the Ghost subs deliver (the stock subs are pretty good in that aspect), but rather bass clarity, which for me was the weakest point of the original system.
Oh, and let me just say that the service I received during my purchases at Bavsound was top notch. They respond super quickly and handle all issues professionally.
