Default JBL in my WagonR

Its a simple no frills setup though. No amp/sub.
Had highlighted my requirements here:
http://www.team-bhp.com/forum/1120658-post82.html
I went to Elegent today with the following configuration in mind:

Front: JBL GTO 437
Rear: JBL GTO 937
HU: Pioneer 3050UB/4050UB/5050UB.

Had a budget of about 10k.

However, i was told by the dealer that JBL 437 is not available with them, so he recommended GT5-S204, the other 4 incher. Frankly i myself don't know how good or bad it is, only time will tell.

For the rear, he said that GTO 937 was replaced by GTO 938, so had to settle for it.

HU is Pioneer 4050UB, with USB cable in the golve box (as suggested by backseatdriver):

This is the final configuration:

Front: JBL GT5-S204
Rear: JBL GTO 938
HU: Pioneer 4050UB

Total cost = Rs. 11300
Less = 1800 for old Sony HU

So far the difference between Sony and Pio+JBL is pretty evident. However, i feel the treble needs to be adjusted as its a bit high. Will work out the settings in due course of time.

the increased treble may be due to the slightly bright nature of JBL speakers. there is a small switch on the tweeter in the JBL 938 that needs to be pressed/depressed in order to tone the treble down;
also, what EQ settings has the installer dialled in????? is the EQ on flat or has it been altered. post some pictures of the settings if you are not well versed with them. everyone here will help you out!

Actually i am yet to see myself what the settings are. Was too excited to explore anything. Will do so tommorow and post pictures as well. Yes there is a switch on the speakers. I was wondering about the same. Does depressing the switch increase or decrease the treble?

Right,just checked the settings and the EQ was indeed set to Flat. I have changed to preset "Powerful"
The settings are as under:
FAD R2
BAL 0
EQ1:
L=+4 M=+1 H=+4
EQ2:
HI 10kHz Q1W
LOW 80Hz Q1W
MID 1KHZ Q1N
(I have no clue what Q1W/N etc mean)
Loudness: MID
HPF: 50Hz
Bass Boost: +3
Tweeter switch unpressed (0db).

Now this certainly sounds much improved.

THIS IS WHAT I WOULD DO first, and then start tinkering with each setting one by one till I reach what I like!
I have changed to preset "FLAT"
The settings are as under:
FAD R0
BAL 0
EQ1:
L=+0 M=+0 H=+0
EQ2:
HI 10kHz Q1W
LOW 80Hz Q1W
MID 1KHZ Q1N

Loudness: Off
HPF: Off then 63Hz since its the GT5-204's or else 80Hz
Bass Boost: 0
Tweeter switch pressed (-3db).


If this were my setup, I would keep it this way. My 2 cents only. Depends on your listening style!

try setting it to flat first and tuning everything else correctly, esp equalizer

good if you like your sound from behind.else I'd set it to 0 or F1
Quote:
Loudness: MID
again, turn this off, we can check if we need this later
Quote:
HPF: 50Hz
unless you have a sub, leave it at off. You'll end up with less deeper bass because of this
Quote:
Bass Boost: +3
lets turn this off for now , and lets use the EQ insted to compensate
Quote:

you forgot the Sound retriever DSP. Its not in the audio menu. Its in the other setup menu. set it at OFF initially .
Now you're ready to tune the EQ
Quote:
BAL 0
EQ1:
L=+4 M=+1 H=+4
dont push all of them too high. make sure that you normalize the EQ ( ie bring the least of them to 0, and the others correspondingly) for ex, instead of 4-1-4, 3-0-3 should do. tune it such that your system sounds balanced ( remember we are going to be activating the bass boost etc later)
EQ2:
Quote:
HI 10kHz Q1W
LOW 80Hz Q1W
MID 1KHZ Q1N
(I have no clue what Q1W/N etc mean)
Looks fine. Q stands for the sharpness of the eq curve. Q1W,Q2W,Q1N,Q2N, with Q1W being the least sharp, and Q2N being the sharpest. try putting the mid EQ to Q1W as well ( wont make a difference after you've set the eq to 3-0-3, since mids will be boosted by 0 = not at all)



Now that we have tuned the speakers correctly, NOW you can play around with the bass boost, loudness and the Sound retreiver to get the right combo. I'd suggest you keep loudness off unless you use the setup at very low volumes mostly. sound retriever should take care of the highs , and bass boost should take care of the lows

How can you listen to music when evrything is switched off from your HU?? it will just sound like a loud radio no seperation or depth in music.Real test comes when you switch on modes/operations to get it more louder without any jarring and tearing

Good buy mate.
1- How much did the 4050 cost?
2- How much did 938 cost?

You should try the -3db setting on your speakers. Imo sounds better

Great! Will try out as you and Frank Mehta suggested.
By the way, how does Sound Retriever and HPF functions affect the sound. ?

Didnt quite get you. You mean turning on Loudness/Bass boost etc. ? I think as GH and FM said, first let me switch off these and configure the EQ, then tinker with Loudness/Sound retreiver/Bass boost etc. according to my taste, that will be a better approach.

4050UB (Grey) - 5.9k
GTO 938 - 4k
GTO GT5-S204 - 1.5k

In GTO 938, i was told there are two versions- One local for about 2.7k, and original for 4k.

the sound retriever and Bass boost are both DSP's which enhance the sound by adding harmonics. tweaking the EQ with these enabled can be a bit tricky. what works for one song may not work for the other.

HPF = high pass filter. it removes all content below that frequency. the two scenarios where you will have to use it
1. if there is a sub, in which case to re route the bass
2. if the front speakers cant handle the bass, - which I dont think will be a prob with the JBL's

even for # 2, you want to have induvidual HPF's for front and rear ( dont think the 4050 has that) since by HPFing , your 6x9's in the rears are also losing out on a lot of bass

@Decite:Try these options.

FAD R0
BAL 0
EQ1:
L=+1 M=+3H=+2
EQ2:
HI 8kHz Q2W
LOW 40Hz Q2W
MID 500KHZ Q1W (Try playing with 200/500/1/2 which suits you with noticible difference)

Loudness OFF
SLA 0
BASS 1
Soud Retriver OFF

After setting this play your fav track.

Switch Sound retriver ON (1 or 2) noticible difference in SQ
Turn Loud (LOW/MID/HIGH) set on which you feel best
SLA (0/1/2) CD level volume (set on which you feel best)

This will help

Good Googly Moogly!
First of all,its not amp'd. So, the HPF wouldn't help much for the lower freq. of the speaker with just 18W RMS
2) The smaller the speaker, the higher the HPF is. Otherwise, you're derfinitely gonna blow it.
With a 4 incher, I'd say 125Hz max. (this still needs an amp in the equation)

PS: I'll ask the hermit to give you some long lasting lessons.
