Just done upgrading my F10 speakers with FaitalPro 4FE32 for mid and Eminence SD28 for tweeter. Overall a nice upgrade over stock HK speakers. Comparing the quality of HK speakers to Hifi speakers, it seems that HK speakers is better build with rubberized cone. At lower volume, there is not much difference but once I turn up the volume more than 50%, I can hear the new speakers can play louder without distortion. Normally in my F10, I can't play too loud as the stock HK speakers will sound harsh. My next move is to replace my wife G01 with Scanspeak speakers but I need more time as the tweeter can't fit into the housing so I might need to cut and fabricate new mounting. My wife want to keep a stock look so another option is to swap out the existing Hifi speakers and replace with HK speakers I rip from F10.

Nice write up. What speakers did you show in your pic? It would be nice to have the standard HiFi vs HK vs your new speakers shown side by side.

[pierreye]

From left, Scanspeak D3004 tweeter and Scanspeak 10F/4424G00 mid, Eminence SD28 tweeter and FaitalPro 4FE32, BMW Top Hifi Tweeter and Mid.

Will do a comparison between Hifi speaker from G01 and Top Hifi F10 speaker. Stay tune.

[pierreye]

Here's Top Hifi speakers from F10 compare to Hifi from G01. You can see the different material use and tweeter is smaller for Hifi option.

Nice write up.
What turn me off is need to mod the plug, and the mounting frame as well??
So it is not true Plug and Play?

[lo_cheng]

I just look at Bimmer tech amp, seem like is same amp, but the spec is a touch differ.
DO you know does Bummertech amp also need to cut the connector?

I think it caught them out slightly BMW changing plug design on newer models, G01 was the first, pin layout was the same just a plastic tab in different position

It maybe they are now shipping with new plug? Although I suppose stocks would still exist with old plug, would be worth emailing Audiotec fisher to see, I did get them to confirm it was safe to use and they were very responsive

If you look at Bimmertech revenant amp detailed specs they are identical just the outer case is different and it comes pre-loaded with a sound file whereas Match7up you have to load a sound file once connected but the whole point is for it to be user customisable so that's no great problem

Not a really difficult mod but annoying none the less. Revenant amp problem is the preset tuning can't be change and I think that limit the potential of the unit.

I love what your install. I'm looking to do the exact same thing with my G01, i.e. change out factory amp for Match Up 7BMW and install a sub under the trunk floor mat only I'll be using a 10" Kicker Comp Sub with a Kicker CX 300.1 Amp. The sub and amp are not great but I have it left over from my old car and don't feel like spending more since the Match Up 7 is pricey.

Would you mind sharing the dimensions of your box? 0.75 ft3 is just right for the sub I plan on installing and since you had success, I figure I won't try to reinvent the wheel. Also, how exactly did you mount the sub amp? I see that you were able to hide it behind the panel and I would love to do the same. Feel free to share any other details you think may be helpful. Never done anything like this so I could use some help.

Many thanks!!!

[pierreye]

The box I build is around 0.75 ft3 so should be good fit. Can't remember the actual dimension but remember to measure the bottom of the trunk space as it is slightly slope to bigger opening at the top. The sub amp is mounted onto a thin aluminium plate. You can also use acrylic panel for mounting. One thing to watch out is make sure your amp is low profile as it might interfere with the cover. My cover barely fit as the amp after mounted is slightly protrude at the bottom. Also, need to drill a small hole at the lower trunk storage mold to feed the subwoofer speaker wire thru. Good luck!

I just got the Up7BMW installed this morning.
Just default SUV profile for now.

First 30min of listening, I am happy with it. Can't find the right word, I guess I feel it have more details and the sound feel "Fuller".

I do NOT plan to install additional amp and sub in the boot. Want to play with the tuning of the Up7BMW before I decide should I replace the under seat sub as next step,.

I do have some question for you about tuning, as it is first time I doing this.
I do NOT plan to tune it to focus on driver seat only, just want to start with some basic tune based on the SUV Profile.

1). Does your tuning based on turning the Treble and Bass in Head unit Flat?

2). For change the 4" speaker crossover from 125hz to 150hz with 24db/oct slope. So it is changing the High-pass to 150hz, correct?

3). Because the 4" crossover is 150hz, I think the factory underseat subwoofer should run between 150hz to 50hz?
So it would be High-Pass = 50hz and Low-Pass = 150Hz, 24db/oct slope? Am I correct?

4). Increase subwoofer gain by 6db


I those 3 item will be my first "adjustment" based on SUV profile and go from there.

Please let me know am I correct about those cross over setting.
Thanks

1). Does your tuning based on turning the Treble and Bass in Head unit Flat?
everything flat in head unit
you set 1)your time delay, 2)cut off low pass hi pass for subs, front speakers rear and center channel, 3)adjust frequency responce to your liking and once done you fine tune head unit equalizer depending on volume your listening your music at. usually at high volume i tend to diminish highs so wont sound to harsh


2). For change the 4" speaker crossover from 125hz to 150hz with 24db/oct slope. So it is changing the High-pass to 150hz, correct?
yes, however better high pass at 125. 150 would be too high

3). Because the 4" crossover is 150hz, I think the factory underseat subwoofer should run between 150hz to 50hz?
So it would be High-Pass = 50hz and Low-Pass = 150Hz, 24db/oct slope? Am I correct?
low pass 40 to 50 and high pass 125. the less broader the better for the subs to work since it wont need to go all over the place and focus on the low end

4). Increase subwoofer gain by 6db
depending on your subs and how you set your frequency response. usually freq response shoud be +3/5 db from 40 to 400. then decrease between 400 to 600/800 otherwise would sound muddy.

If you do not wish to add a trunk sub and want deeper bass, I would suggest getting Bimmertech Alpha underseat sub. You can get the 2 ohm version for higher output.

Always set your head unit to neutral settings (means no treble, bass or fader adjustment) as we'll use the delay, level and EQ in the amp. You need a measuring mic if you want to do your own EQ.

If your tuning is not driver focus, you can set your mic between driver and passenger seat for delay and level measurement.

For 4" speaker, the lowest I would go is 125hz. For sub, you can try 40 hz to 125hz. If you feel the sub is strain, try 50hz. I use 24db/oct slope LR. As for the subwoofer gain, I'm using JBL target curve.

Just based on my observation, the BMW Hifi speakers does sound harsh on higher volume especially the high compare to my F10 custom speakers using Faital Pro 4FE32 and Eminence SD28 with 2nd order crossover.

Thanks..for your input

What I find is very difficult to adjust EQ, as it is not like adjust each feq on the head unit. Have to adjust, load, listen. and repeat.

[lo_cheng]

I just got my "Base" ready to load tomorrow (When I find time).
Basically this is my setting as starting point. It is based on Standard SUV profile.

1). Front L/R High-pass = 125. Distance = 70CM, Gain = 1DB (It was 0 in SUV Profile)
2). Rear L/R High-Pass = 125, Distance = 80CM, Gain = -4DB (It was -5.5 in SUV Profile)
3). Center High-Pass = 125, Distance = 60CM, Gain = 2.25
4). Sub Low-Pass = 135 (for some transition) , High-Pass = 40. Distance = 40CM, Gain = +4DB
5). Line Out is mute

didn't touch any EQ at all. Will load this as base and see what happen first.

Without a mic, it might be more of a guess work. It's easier when using a mic, mute all channels except the one your want to measure, play the white noise and measure. It's not that tough.

I never have Logic 7 or HK before.
So you saying with Hi-Fi + UP7BMW DSP only already sound better then HK ?

I finished my day with this adjustment based on standard SUV Profile.

1). Front L/R High-pass = 125. Distance = 60CM, Gain = +1
2). Rear L/R High-Pass = 125, Distance = 80CM, Gain = -4db
3). Center High-Pass = 125, Distance = 70CM
4). Sub Low-Pass = 125, High-Pass = 40. Gain = +4db
5). Line Out is mute


BTW, I notice the EQ setting in Limousine profile is very differ to SUV one, but they are same speakers
I want to try apply the same setting above but based on Limousine profile and see how it compare

[pierreye]

Personally I feel Hi-Fi speakers + UP7BMW > stock Logic 7 system. But I'm comparing system from X3 (Hi-Fi) to 5 Series F10 (HK Logic 7). But once I upgraded my speakers in my F10, I feel it sound better than my X3 except bass as I add a 12" trunk sub. I'm going to upgrade my X3 speakers soon with Scanspeak speakers.

For distance, did you measure with measuring tape to ear level?

For Measurement, I think I did it wrong, will do it again.

But I think it is just "relative"?

e.g. Front L/R vs Center.
Front 0, Center 20cm, would be same as Front 50, Center 70. because what matter is how much DIFFER .

Am I right?

[lo_cheng]

Ok, Done my adjustment today. Mainly fix the wrong measurement I done before.
Again, I haven't touch the EQ, because I don't have MIC to do it.
and it is not like adjust EQ in head unit that I can just sit there and adjust. So I leave the EQ as standard SUV profile.

1). Front L/R High-pass = 125. Distance = 80CM, Gain = +1
2). Rear L/R High-Pass = 125, Distance = 80CM, Gain = -4db
3). Center High-Pass = 125, Distance = 95CM, Gain = +2.25db (unchange from standard SUV Profile)
4). Sub Low-Pass = 125, High-Pass = 40. Gain = +3db
5). Line Out is mute

Overall, I am very happy with it. Much more details, better separation, sound is much FULLER.

I think this is it, next improvement will need to come from replace the under seat sub.
Which I saw some you-tube video the under seat sub is Glue on, not screw on, which make it more difficult.

That's true it's relative. But it doesn't matter, just use the actual distance to make it easier. The system will automatically calculate the relative relay to each speakers. If you got it right, you will hear the sound stage is wider.

I did it again today and i notice the sound stage is wider.
