Here you go.

Issue: Center channel speaker used by BMW is dull, muddy sounding and lifeless.

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>
Center channel is critical to a great sounding system as vocals and other midrange tones come out of center channel.


So the project is to replace the center channel speaker with something better.

<o:p></o:p>
I decided to use FOCAL 100CA1 4” Coaxial speaker.
This is a great sounding speaker and it fits perfect.

<o:p></o:p>
Search on line or in eBay for the best deal.


This is an easy job. Takes about 1 hour tops.


Please see attached DIY step by step procedures.


Sorry it took so long. 'Been very busy at work and at home.


Enjoy.


Dan

Thanks for the kind complements folks.

My own personal opinion: Logic 7 system sounds really good.
Compared to what BMW installed on my E39 M5 (M-Audio) - Logic 7 is a big improvement.

If you have no plans on sharing the output of your stock stereo system with the rest of cars around you within a 2 mile range - Logic 7 is good enough. Of course there's always something better out there depending on how much you want to spend.

Anyway, LOGIC 7: Amp is adequately powered, the subs are great, speaker drivers however could use improvement especially the center channel and the tweeters.

The tweeters are harsh sounding when driven hard. That's why I already replaced mine.
See here. Much better now.

Next was center channel speaker.
To recap, center driver is muddy sounding as BMW used a single cone driver with no tweeter for the center channel.
Replacing mine with the Focal 100CA1 made a huge difference in sound quality and imaging.

I'm very happy with mine now. Maybe replace the rest of the speakers later with Focal's but for now, it is a much better sounding system compared to stock.

Again, this center speaker replace is an easy mod, and I highly recommend it if you plan on keeping your stereo system mostly stock.

Hi, thank you for this write up. I'm going to attempt to replace the center speaker first. How long did it take you to change out the tweeters?

About two hours to replace the tweets.

I recommend you disconnect the battery before starting work and hopefully, disconnecting the air bag connectors wont throw a fault on the computer.

I bought mine from Crutchfield. I do find them in eBay from time to time.

Note: I have no affiliation to this vendor and I dont know how good they are infulfilling orders.
My vote is to order from a good company like Crutchfield.

Here's the best deal I can find:
Focal 100 CA1 (100ca1) 4" Speakers Car Speakers Car Audio Car Audio, Video, & GPS Navigation - Sonic Electronix

Or just buy them from Crutchfield.

Is the DIY same as M5?
Sorry, I dont own an E60 M5 so I wouldnt know.

Hello Dan,

I have read your posts regarding the upgrades, very nice write-ups. I am going to upgrade the center to the Focal you also used, if you still have the extra let me know and how much.

Also, I am going to upgrade the door speakers - do you recommend the same mode Focals for that? I do not know much about that speaker besides the reputation for superior sound! Or should I use a mid-range driver since the tweeter is separate in the door?

Lastly, I have some 1" Kicker brand tweeters from a previous install, don't know if you know anything about these. If not I may go with your recommendation of the Polk Audio tweeters.

Thanks in advance for your help.

Mark.

Hi Mark.

Glad to hear you liked my DIY write up and I hope it helps you when you do yours.

1) Center channel is very easy to upgrade. Just follow my step by step instructions.

2) The door speakers are not easy to do. There is a nice write up here on how to replace the door speakers.
Kindly do a search.

I decided not to replace the door speakers as I just dont want to do some cutting and hacking yet on my M6.
My vote for speakers and tweeters are Focal. Simply sweet sounding speakers for a good price.

For stand alone tweets, I love Polk Audio DB1000. Silky smooth highs.
I've heard of Kicker, but I am not a fan of them. To my ears, they are a little harsh sounding when driven hard.

3) My other Focal coax speaker is already sold to another member here.
I even cut the extra tabs for him already so that it will be plug and play for him.

Good luck to you and let me know if I can be of help.

Dan

Thanks Dan!

The center is straight forward, I have done complete installs on a half dozen cars over the years, including my previous Porsche. So I am comfortable pulling apart dashes, yanking off door panels, etc. I did see a post in my searches where another member had replaced the door speakers and used some epoxy. I didn't dive that far into the door research and it sounds a bit more difficult, but not horribly complicated. Regardless, that person used a different Focal speaker - the one that you are using for the center is pretty economical so I thought perhaps I get a matching set into the door.

My weakness is not execution, it is on the best speaker for the application. In my last car I was lucky that some folks had ironed out that the MB Quarts were not the best speakers because of the interior acoustic dynamics. Turns out that JL Audio (or Focal for those that wanted to spend the money!) worked for that car. Anyway, I will start with the Focal center and the Polk tweeters and see how much I like that improvement.

The Logic 7 is real nice, but as has been noticed, it lacks for all types of music. The system I installed myself in the Porsche could handle every genre and sound great. I had JL Audio mid/high with A/D/S 6" drivers in the door handling low/mid. The last piece was a JL Audio 8" subwoofer with custom fiberglass enclosure. The JL sub did not require any port hole and is designed for a smaller, low air volume enclosure. The sub was driven by a Sony MTX amp while the rest were driven by a 6 channel A/D/S powerplate amp. Very clean sound, I miss it now that the car is gone.

I have some speaker shopping to get on with now...

Hey Dan,

Revival of an oldie but goodie thread here! I had advised another 6 owner that the Focal is a great upgrade since I have been so happy with my center channel. He noted that the factory speaker is 2 ohm and that the Focal is 4 ohm, he questioned me that it would halve the power to the speaker? I am not enough of an expert to properly answer that question, I am better at installing than knowing the electrical engineering part...

Thanks in advance,

Mark.

Hi Mark, sorry for the late reply.

I was in the hospital for a couple of days and was just released today.

Yes, BMW OE speakers are 2 ohms and the Focal are 4 ohms.
The OE BMW amp is powerful enough to drive a 4 ohm speaker without any problem and there is no noticeable mismatch on speaker output either.

So in summary yes, the Focal is a very good replacement for the stock center channel speaker and the BMW amp has enough power to drive it.

Anyone wanna go half on a pair of the Focals that Dan suggested? We only need one each for our centers. I have exclusively used Focal in my Cars over the years and I can honestly say they are one of the best speakers out there.
