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.

I write this review with love for Bavsound and in the hope that someone will read it and take action for improvement. I believe Bavsound makes a exceptional sound system however they need their customer service support systems to match the quality of their equipment. I count myself as a loyal customer in the fact that I had purchased a Stage One speaker system, Ghost subwoofers and revenant amp for my BMW M240i about seven years ago and was very happy with the system. I drove a 911 for the past five years but recently sold it and bought a BMW Z4 M40i with a manual transmission and so wanted to get the same system installed. Unfortunately I found out they no longer made the revenant amp but I went ahead and purchased the Stage One system and Ghost subwoofers. I decided to install just the door and center speakers at first because the insulation into the rear panel of the Z4 is very complicated and I wanted to ensure there were no rattles from the factory. I had the installation of the door and center speakers done at a professional audio shop and it went fine. When I finally decided to install the Ghost subwoofers and midspeakers into the rear panel, I chose to do it at the BMW dealership to ensure the highest level of quality for the disassembly and reassembly.

I cannot share the full level of details of what transpired over the next week due to the 5000 character limitation. The short story is I dropped my car off on Thursday morning at BMW expecting it to be complete that day. I got a call from the BMW technician saying that the midspeakers did not fit and I needed to come down to the dealership. I went down and saw that the speakers obviously would not fit the OEM bracket and took pictures. I had tried to contact Bavsound on the way to dealership and found out there is no customer service number. I sent an email with the pictures and got a response saying to watch an installation video because they had verified that the speakers were correct. I asked if anyone has looked at the pictures I sent and got no response. After a number of different emails I finally got them to look at the pictures and acknowledged that I had the wrong speakers. By this time it was Monday and my car was still sitting disassemble that BMW. I explained I was going out of town on a trip for a week and needed the speakers sent overnight. Instead they said they were going through a warehouse transition and sent the speakers UPS ground. I got the speakers the following Friday afternoon but I was leaving on Saturday morning for my trip so I had to wait until I got back to take it back to the BMW dealership and have everything reassembled. This is by far the short version of the story and does not at all represent the amount of time and stress I experienced trying to get Bavsound to support me. In all my car sat disassembled for two weeks, I had to send dozens of emails of which only a few got responded to, and had to make several trips to the BMW dealership. I even called some distributors in Suffolk California trying to see if I could get some support and was told they had the same issue with Bavsound being slow to respond. The good news is once the system wasn't installed it again sounded very good. As I said in the beginning, I hope that this review will be read with the intent of improving their overall customer service experience and have it match the quality of their sound systems.

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.
