Hey all,

This is my 2nd post today about my system. I recently added some rainbow SLC 210 components to the front of my e92. I'm driving these with an xd600/6. Underseat, I have the sws-8 2ohm subs.

I notice that the sound up front is not full. It's missing "body". Pardon me, I'm not an audiophile. When I fade to the back, the sound is full, when I fade to the front, the sound is weak and shitty - almost tinny, almost empty feeling.

Any thoughts, or advice? If you need more info, please let me know.

Thanks
partypat

What is your gain and crossovers set at?

[partypat]

crossover is passive. I had input gain on the xd600 set at minimum for channel 1&2.

Earthquakes might be the reason why.

There's plenty of posts here why the SWS aren't exactly ideal underseats.

More than likely, you're missing a truck ton of music from the ~100-~300hz range.


But yes, the point at where your sound is crossed over might be a big help.

Please post amp crossover settings, and where are you getting the input signal?

THIS,

plus possibility that your tweet+mid are reversed coming out of the xover.

[partypat]

Can you clarify what you need for 'where are you getting the input signal?' question?

I have a technic harness that routes into my xd600/6. Also, the xd600 has input gain, a hp/lp setting but no crossover setting.

thanks

Crossover frequency knob is on the right of the HP/LP switch.

With the XD600/6 settings at min gain for front and rear channels, 9 o'clock gain for underseat woofers (7 o'clock is minimum), HP at 135Hz for front and rear speakers (that is 27 clicks on the frequency knobs) and LP at 174Hz for underseat woofers (30 clicks)

Read the xd 600/6 manual
These settings are not for the speakers you have but are in the ballpark.

HE HE, I got it now I am not an audiophile, I'm a guy with a computer and a car. HA! Both Ch 1&2 and Ch 3&4 are at HP 174Hz. Thoughts?

I saw filter frequency, that didn't mean the same thing as crossover in my mind.

Thanks!

[Wongway]

Am I reading that right? You're letting anything from 174hz through to your tweeters and mids?
I mean, this isn't the reason, but wouldn't you want the mids to be highpassed around 300hz? tweeters highpassed around 4000hz? That just looks like risking your tweeters and mids getting blown...

The thought I think everyone might be driving at, is are you sure that you don't have that switch setting to Low Pass by accident? Thereby only sending low frequencies to the tweeters and mids (that they can't play?)

I'm sure the swtich is at HP.

I don't know what channels are going where....but:

Ensure your Front Mids & Tweets are HP
Underseat are LP
Rears are HP

Technic can comment on the input channel mode for whichever harness version he sold you.

and again, make sure your passive crossovers are wired correctly.

My channels are correct, 1&2 front, 3&4 rear, 5&6 summed for underseats. I've double checked my component set up with the tweeter/mid/xover in the doors. So it looks like, I may have too much gain in the front right now ( at that gain, the front sounds WAY better ), but is it too much, or is it a 'salt to taste' sort of thing?

Thanks

[taibanl]

Hmm, everything sounds ok by your description...

Try a straight 200hz HP/LP on everything. Ok to have some extra gain up front. check your switches to make sure they are properly seated in the HP/LP as appropriate.

[Wongway]

Just to be sure...

In Ctuna's pic, I see the proper wires leading out of channels 1-6...

In partypat's pic, I see no wires leading out of those spots. Did you disconnect everything before taking that picture?

[ctuna]

How are your door components set up?
Did you get and install the passive crossover that comes
with most all component sets. They usually have a jumper
to balance the gain between the tweeters and 4 inchers
and as a rule they need to be set to the neutral or negative
position. Mine are set to -3db.
The front door speakers should be able to take some gain .
Also with the fronts I would set the crossover on the amp higher
I would try around 200 hz to start with .

Just curious. Why is there a gap between your LP frequency and your HP frequencies? Shouldn't the HP pick up at least as low as the frequency where the LP left off? I understand that might not be the case for the rear channels if they aren't getting a full range signal.

[partypat]

thank you.. my crossovers are fully sealed no jumpers.

pat,

This really does sound like a cross-over problem to me. Do you have the "round" passive x/o's with those Rainbow components? The reason I ask is because I believe those can be bi-amped, meaning that it is easy to hook them up incorrectly. Also, I thought those did have multiple variable attenuation settings for the tweeter on them.

If you have no jumpers then I suspect your problem is Very likely in the install or the lack of the right crossovers.

They do. There's a lot of flexibility in them.
