The dreaded "base audio" upgrade...

e90 logic7 center -- better than stock, but not by a whole lot. bass is tiny bit better and it seems to play a little louder. not really worth it imo.

e90 individual audio center channel coaxial -- not amazing but better than stock base audio midrange. of course you would expect the treble to be improved since you are adding a tweeter..

next step is to try the individual audio separates up front i guess...

All door speakers in the e70 base system are that smaller e90 size (center channel and rear door/shelf speaker size)
I actually changed all my door speakers to that logic 7 speaker and added the smaller logic 7 tweeters to the blank door triangles. Did not do the rears even though I do have a set laying around as the issue with rear door tweeters are the base door cards do not have the cutout.
Hope that info helps

Just my 2 cents, if anyone thinking about upgrading a top hifi sound system in their E70 X5, don't do it. The components are not inferior. If you look inside a top hifi amplifier you will see discrete circuitry with Rubicon Blackgate caps. The amps are made by Lear Corporation. The speakers are carbon fiber and have small but powerful neodymium magnets, Siemens Polypropylene caps for the tweets, The Subs are made by ETON. If the sound is not good it is because the inside plastic panels need rubberized sound deadening. Do that and you will save yourself from destroying your car. Somehow Bavauto generaly says how cheap the BMW speakers are, mine are 8 years old and never had issues. The only issues I had were rattling panels when I cranked it up, that is all history now. Their is also a provision on top high fi amplifiers where you can add a cooling fan which can be had for 5 dollars at newegg.com. I will say, before 2006 BMW audio sucked. Base audio model need alot of help. Just my 2 cents.

I finally decided on MB Quart set for my X5... only question now is, how do I get the cheap 6.5" sub out of the plastic enclosure? Mine looks to be glued in place. Some other pictures show for screws/bolts at the corners...

@SchweetMunkie - Please keep us updated on your progress. I have the base audio in my 2011 X5 35i Sport Activity. Although, I don't think it sounds as bad as others say, I wouldn't mind some small upgrades. Maybe starting with putting tweeters in the empty covers! I will definitely subscribe to this thread and follow your progress. Thanks!

Whats up fellas!

A couple of weeks ago I placed my order with BavAuto, they are having a great deal something like 45% off plus an additional 10% off if you get there newsletter. Long story short, I have the PIECE OIF SHIT base audio setup, with NO tweeters and NO front mid speaker.

Done some extensive research and read plenty of reviews and the best deal out there without going really high end and blowing a grand is the BavAuto. The one disappointing fact is they have a 6 to 8 week delivery on the kits. I called in and the guy I spoke to was extremely helpful and it seemed like a decent upgrade.

Sitting tight and waiting for it to arrive, will post up a review once installed!

Happy Holidays everyone...

I ended up just finding a set of logic 7 speakers and it enables me to have tweaters in the OeM location no modifications and it sounds great

This is great to hear. Did you notice a significant improvement? This may be a dumb question, but are the speaker wires already run to the empty tweeter location? Sure don't want to get into the dash!

Also, what model number did you use? There are several different versions of the tweeters on Ebay.

Appreciate the input!

yes there was a great improvement.
the tweeters actually pig tail off the mid speakers.
they have 2 ports, 1 for the audio in, and 1 for tweeter out.
tweeters were very easy to install.
there are a bunch of different part numbers that are all the same logic 7 but out of different cars/ model years.

4x of this 6513 9143121-01 or 65139142512

tweeter part number 2x 65136964012

Bumping this oldie: Anyone recently do anything to improve base audio? I ahd the logic 7 HK system in my e90 and freaking loved it. The basic X5 system just doesnt hold a candle to it. I'm hunting around for a set of the front mid and tweeter L7 speakers, and I guess that'll be my attempt to improve the sound quality. I sure do miss those 9" subs under the front seats though....

New to me, 07 E70 with nav, top hifi. I upgraded front door speakers, and added aftermarket amp between OEM amp and these speakers plus the under seats. So remaining speakers are fed by original amp, not aftermarket one.
Now the PDC, and other chimes are crazy loud! Either due to more efficient speakers and/ or the new amp. Any way to code volume of chimes, or select which speakers the warning bells go to so as to avoid the front door speakers? My idrive unit CCC does not have a volume setting for “Tone” as some other posters have suggested.
