Door Speaker size question
 

Will 6.5 inch round speakers fit as replacements for our current door speakers (E53 no premium sound)? I know BSW is offering stage1 replacement speakers but I'd like to explore other options as well. Thanks

.
 

6.5" will fit on both front and rear doors, i have the ALPINE-SPX-F177R (pushing 90 RMS each door) on my rears and the DLS UR6i's on my fronts (pushing 280 RMS each door).

Thanks Hiten50. Alpine was one of choices. Was there a big improvement in sound?

Massive, I powering the Aplines with a Genesis Stereo 100
and the front DLS UR6i's are powered by a Genesis 4 Channel (Bridged)

And you will see a big difference just changing the speakers and leaving the factory amp.

BSW's systems are great for those that don't feel comfortable doing this themselves and need some guidance, but if you have any experience doing car audio, the speaker swap is an easy DIY.

I swapped out my fronts with MB Quart components (same ones BSW used to use) and it made a world of difference. The big difference was I paid about $90 for the speakers!!

X5Dawg,
I wish I had experience in installing speakers. But Nada. So its really a first. But then again so is the steering wheel install, angel eyes, etc. I just can't stand the inferior sound of the stock X speakers:confused:

What model of MB Quart speakers did you use?

Discus, 5.25"

Just curious but don't you have to replace the mid range to with the 2.5 BSW, to get the same system as BSW

280RMS.... ouch how's your hearing?...... in my car i have ~75 RMS to 4 corners and 12" Kicker CVR in the trunk sealed getting about 150RMS and if i listen to it more than 60% volume i get lots of ringing in my ears afterwards

Do a search....only certain 6.5's will fit without modification.

This confuses me. A speaker with a round mount flange of 6.5" diameter, will that fit?

What is the spacing of the mount holes of the original BMW speakers?

The OEM woofer is mounted inside a plastic tube. The inside diameter of that tube is around 163 mm. A 6.5" (165 mm) will not fit without modification.

Not sure about the spacing of the mounting holes.

I was referring to the door speakers - the mids, not the tweeters. Anyone help with the actual size of these?

I don't have the OEM sub box.

Planning to upgrade the front door speakers of my E53. In as much as I would love to have the BSW plug and play Stage 1, it'll cost me an arm and a leg (and probably everything else) to have it shipped here. Sorry bsw :(

So, I decided to scout around the aftermarket shops since the recommendation of the folks here are to get a 6.5" speakers. Went to one shop who had MB Quart ESA 216 6". And another with Infinity Kappa 60.7CS 6.5".

What do you guys think? Will any of these work without too much installation hassle?

Is your X DSP or non-DSP?

The Discus will require an adapter ring for the the install. The speakers in those cars are approx 6.25" round midbass drivers. Many 6.5" speakers will slide down into the housing with a little bit of wiggling and a bit of shaving is sometimes necessary.

If you are amping them then you don't really need to worry about the midrange. It ends up being easier to tune the system running a 2 way system. We are working on a plug and play amplifier(stage 2) for our stage 1 customers! Will be ready very soon!
