Query on JBL

Vivekphadnis · 30th August 2005, 23:39

I bought JBL coaxials since it is difficult to accomodate components in an Alto. For the front, it is the 426e (4 inch) and 936e (6x9) for the rear. 936 is Rs. 4750 and 426 is Rs. 2500.
The sound is decent. Surely, component speakers would sound better but I was on a very limited budget.
About the HU, it is difficult to tell for sure whether a given set is genuine or fake. It needs a keen eye to observe the soldering and PCB quality, the components inside the head unit. The labels can be duplicated easily.

Thank you for ur reply Vivek.
Even I am on almost same budget as u were, I love the sound quality and tweaking options in pioneer 5750, even if its a fake.
speakers I won't get JBL's in chandigarh and don't hv time to drive down to delhi , so I will settle for blaupunkt or pioneer one's.
anyways thank you, happy listening

Thank you soooooooooooooooooooooooooooooooooooooooooooooo much Sam, I called up Balmeet in Delhi and some Ms Parmeet Narang from his office gave me number for JBL Dealer in Chandigarh. If anyone else wants the details they are as follows :

Mr Baloni
Ph # 98153 18854
Supreme Audiotronics
SCO 110-111, Sector 34 A, Top Floor, Chandigarh.

I will go check the 936e and 426e tommorow. Thank you once again Sam.

zzzehar · 31st August 2005, 16:55

Also Navin I couldn't find any details of the Authorised Pioneer Setups like you mentioned and provided the link for the same. Please let me know where they are?

zzzehar · 31st August 2005, 18:04

Also what do you guys say about Pioneer TS-A6991R 5 way Speakers with 80 W RMS. I searched a lot on this forum as well as others, and found them to be Rockin' ! What do you guys say?
For 3900 INR this doesn't seem to be a bad deal in comparison to Rs 3250 50W RMS Blaupunkt ones or JBL's GTO 936E for Rs 4750 100W RMS. Anyways I am checking out JBL's 2moro so Nothing is final as of now. Let's see how SAMM Rocks ;-))

Sam Kapasi · 31st August 2005, 18:50

lol
you're welcome Zzzehar.

navin · 31st August 2005, 22:40

i dont think i mentioned that did i? all i said was there are others on this forum who claim that pioneers has authrosied sales agents. sam has clarified one issue (Autocop) on another thread.

i suggest you trust your ears more than Sam, me or any other forum. it is your money, your ears and your music. if you like it dont worry about the rest.

With a budget of 15 k you can get components, speakers and an amp. Forget the woofer for now.
However in Infinity you wont get all 3 in that budget.
I say go for JBL GTO506Ce - Rs 5500/-
JBL GTO 636e - Rs 3950/-
JBL CS 50.4 amp - Rs 9500/-

If thats over budget, buy a sony amplifier. thats pretty good at that price.

Sam,
how do you compare Sony 504z with JBL CS 50.4 amp..which one has higher wattage?? let me know...since I would want to make a decision quick

aseem · 1st September 2005, 01:51

They are almost equal on power specs. However JBL has better sound but is prone to overheat. Below are the specs:

JBL CS 50.4:
Specifications:

Max Power : 400W
RMS Power @ 4Ohms : 4 x 50W
RMS Power @ 2Ohms : 4 x 75W
RMS Power : (Bridged @ 4 ohm) 2 x 150W
Frequency Response : 10Hz – 30kHz
THD : 0,10%

Sony 504Z:

•Maximum Output Power:
4 Ch x 100W at 4 ohm
2 Ch x 125W + 1 Ch x 250W at 4 ohm
4 Ch x 125W at 2 ohm

•Rated Output Power:
4 Ch x 50W at 4 ohm (0.04% THD)
2 Ch x 50W + 1 Ch x 120W at 4 ohm (0.1% THD)
4 Ch x 60W at 2 ohm (0.1% THD)

So both have RMS of around 50 Watts at 4 ohms. For the subwoofer in the bridged mode, the Sony produces 120 W RMS and the CS 50.4 produces 150W. So ideally both are not suitable to drive big subs. The Sony has a High Pass Filter and Low Pass Filter as well. Between the two of them, if you are just going to use the amplifier for powering 4 speakers, than I suggest the JBL.
Else if you want to power 2 speakers and a sub, than I strongly recommend the Sony. Lets see what Sam has to say!

Sam Kapasi · 1st September 2005, 09:35

Well I pretty much agree on almost all points, except:
The JBL is NOT prone to overheating (where did you get that information from aseem?)
and the sony makes amazing value for money.
They BOTH have high and low pass filters.

Buffet, to answer your questions briefly:
The JBL has more power but If you're on a budget the Sony makes more sense. For the price, it is indeed a very good sounding amplifier.

aseem · 1st September 2005, 09:54

Hi Sam, I was reading reviews about JBL amplifiers, as even I was faced with the same dilemna as Buff to choose between CS 50.4 for 7k or Sony 504Z. I read many buyers reviews who had bought CS 50.4 and GTO 75.4. Although I cant locate all the reviews but below is one for GTO 75.4:

Over Heats Fast by h2dav July 11, 2005

This amp is huge. It will drain your power system down to nothing then over heat. Driving around with my radio at 75% my amp will over heat and cut off quickly. Even with the amp in an open air environment (windows down). I've tried everything but with the AC on and my volume up it will drain my battery down to under 11 volts. I have two caps and upgraded batter but traveling under 35 mph there's no use.

Sam Kapasi · 1st September 2005, 10:01

Like you said, aseem, that review is on a GTO75.4. That amp is completely different. A different series, different sound, different price, different power. The CS50.4 has very good efficiency and its not prone to overheating.

Cheers

navin · 1st September 2005, 10:11

On the power front the Sony and JBL are about the same. 120W or 150W are not much different. even the difference between 100W and 200W is hardly perceptable (given the same conditions - same speaker, enviroment, power envelope, etc...).

I would recommend this. If you are powering a Sub below 100Hz the differences in the sound quality between the Sony and JBL will be less perceptable esp. in a moving car. If however you are powering 4 fullrange speakers (front and rear) the JBL will sound smoother and less fatiguing.

A system like any chain is only as strong as the weakest link. In many cases I find the weakest link is the enviroement (room). Not much can be done in a car. get good wires - power, speaker and interconnects; get a good installer; and it will go a long way.
