Answer to why hifi system sounds bad!

So I spent a few hours yesterday replacing all the hifi speakers (2ohm) with the logic 7 speakers (4ohm). What I found was the hifi tweeters are 4ohm. I kept the Hifi tweeters in and just replaced the woofers. Now the output of the tweeters is matching the woofers.

I put in the aluminum dome logic 7 tweeters for a short while but i found them a bit harsh and tinny. Put the textile domes back in.

Prior to the woofer replacement, the system sounded really dull and highs were lacking output.

But now it really sings.

... and if you replace all the HiFi speakers -except the HiFi OEM woofers- with the Individual Audio component and coaxial OEM speakers while keeping the HiFi OEM amp then it will sound even better.

The HiFi OEM amp is quite decent for a standard OEM amp. The HiFi speakers are a disgrace, though.

Logic 7 mids are great
HIFI tweeters suck
Logic 7 tweeters suck too

Ideally you want logic 7 mids with aftermarket tweeters

I think aftermarket tweeters are the next upgrade. Which ones do you recommend. Also, i have the L7 mids crossed @ 170hz do you think that is good?

I'm in a minority when it comes to crossover point
I believe Technic/vp etc all say around 150-175
I didn't like that at all (back when I had the logic 7 speakers)
Problem with 150-170 is the mids sound good, but the I can tell the mid bass is coming from underneath me since the subs have to produce sound up to the same crossover point
I had mine set to 90hz between mids and sws-8
But I'd you're giving the speakers, they can't handle such a low crossover point
I was only giving them about 50 watts each

This is where the MS-8 is great
Being able to try different crossover points without getting out of the drivers seat is cool

As for tweeters recommendations, not sure
I was using very old school tweeters that were made in the 80s or 90s
Can't get them anymore

i was just playing with the xover point on the L7s and they sure do sound good. The Hifi would distort under 200hz. The L7s play down to 100hz well. They actually put out some decent midbass, but i am afraid of there power handling with 70w rms. So i put them at 160hz for now.

Hey Technic, quick question. Can I remove the front tweeter pods in the sails without removing the door panels?

The way the pods are attached does not allow removal with the door panels in place. If you force them something may break.

Okay thanks. I was looking for an easy way out.

LOL---I must be deaf. I think my Individual Audio sounds pretty good! CD's sound muddy ( i def hear that), but when the ipod is connected via USB, it sounds pretty damn good.

I didn't. I believe you are correct 2ohms. I was mistaken by the slightly less sensitive L7 mid.

I just want to check. L7 mid is 2ohms? If I use a 4 ohm amp with it, does that mean a cooked amp?

When you say HIFI is that the same as the Enhanced Premium sound that cost $2000? I heard that EPS was the same as the individual sound system and rocks

Technic, sounds like if you have the EPS system / Logic 7, if you just change the Tweeters up front to something else it would greatly improve the sound. If so, which Tweeters do you recommend that would be plug and play? I could be inclined to do this if I don't have to get too technical and can just plop in new ones DIY.

Thoughts?

No. Just make sure the amp is 2ohm capable. Most are.

Hifi is no the same as eps. Hifi is the base m3 system.

I used to have EPS in my old 2008 M3. Now it is HiFi in my 2012 M3.

I posted two threads on my HiFi upgrades...

So all you basically did was replace the hifi speakers and woofers to L7s? And it sounded alot better? I did know they were a direct fit?
