I keep buying many retrofit parts so one seller gifted me 5 L7 mids (with front tweeters) when I bought a few items from him, so basically I got them for free in the lot.

I had no plan to get them but since I got them (again, for free) so I installed them in my E60. My E60 has retrofitted CIC which is coded to output HiFi. I have made my own harness which goes from the HU to the boot and into PDX-5. PDX drives all 4 speakers plus 4 ohm SWS-8 (mono, both side in parallel making it 2ohm). Now since I have put these speakers replacing old speakers (front with tweeters and rear without tweeters, nothing else) I find sound too bright, almost harsh. I don't find it soothing in anyway. I can't say its bad but not sure if this can be called good. Its too loud on higher end.

Staging is better though and music clean. Its just the high end I am bit concerned about. I can't really say its "bad" but its not soothing sound which you can listen for longer. Why is so and what is cure?

Also for this setup what should I set in the gain and lpf/hpf freq. for channel 1/2, 3/4 and 5? Any proved recommendation given my circumstances please.

You need a processor of some type to flatten out the head unit output
and or adjust the frequency response . Read the Audio upgrade start here
sticky about the system descriptions in particular the base system .
If you don't have that one you need to tell us which system you have.

The base system comes with no tweeters and the high end is boosted to the front speakers to compensate. (please identify what you started with)
one solution is a Jl Audio cleansweep which only flattens the output some of the other solutions have processors that allow you to tailor the sound .
I have heard the base L7 speaker are OK but I don't think there is no crossover or only a pair of inline caps to adjust the frequency split.

I mentioned in the original post that I have retrofitted CIC coded to HiFi which gives 4 full range low level signals. Its no longer base speakers system.

I had Alpine PXE-H660 before, that perhaps would have helped here. Biggest trouble with H660 was its complete disregard for rear channel input. My rear PDC was muted due to that, so I had to let it go.

Now I am eyeing on JBL MS-8 but it is not going to happen immediately, looking for some easy fix until I get my hands on MS-8.

No need here.

What is needed is either a treble adjustment or a new set of tweeters from BSW.

Or some tweeters with a Technic style pigtail!

I got an impression from reading various posts across the forums that L7 tweeters are quite good. Why it happens everytime with me that whatever I install becomes "not so good" once installed. Same happened with SWS-8, it was highly rated product with virtually no alternate available a few years ago and now I have been told they are only for <80hz bass and very poor above it. Effectively leaving a big hole in mid freq range.

No worries L7 tweeters are fine

[taibanl]

Its just hard to say if they are the cause of your problem. Youay have a personal preference of a soft dome tweeter

Anything can be quite good if you like it.

In this particular case you do not like the OEM Logic7 tweeters. So either you adjust the treble, get an adjustable passive crossover or simply get another set/type of tweeters to your liking.

I will use it for coming days and see how it goes. If I happen to open my door card I will put back Alpine DDT30 (or whatever it is called which I had before) to see if they make a difference.

Technic, does the L7 AMP have its own eq curve or is it flat? Perhaps there is eq in the amp that attenuated hf?

Yes, it does.

Perhaps thats the reason stock components go well with stock parts. I am extremely tempted to retrofit L7. All I am after is better imaging and clean sound, I am no loud bass audiophile.

If you really want L7 find a cheap ms-8

I wish I could find MS-8 cheap, I will buy it in a blink. Morel front mids and MS-8 is my dream setup. I doubt I can afford them.

Anyone selling MS-8 cheaply :-P delivered to the UK, I will pay for tax/duty and shipping.

[afsar]

Slightly off topic but related, if MS-8 has 8 channels total how do people manage to get extra channel for the tweeters? Do they sacrifice L7 to achieve this?

[taibanl]

The advantage of MS-8 is flexibility...up to a point (8 channel limit). I don't run tweeters on their own channel. They are combined (for me) on the same channel with the mid range, except that they are passively crossed in the trunk.
