I have two jbl lsr6325p studio monitors. I'm not getting any sound out of the main part of the speakers. Only high-end sound is coming out.

If you have replaced the cartridge then it must be the cartridge pre-amp that is faulty. If there are any other functions on the device such as CD, then it will not effect them. Unless there is crackling on any other function then the pre-amp has a problem. The pre-amp itself is generally a single IC. You can find it by following the turntable connection back to the inside of the amp. The signals will pass through the IC before being passed to the main pre-amp.

Damaged component/s at its main power amplifier stage circuit. Leaky capacitor/s can cause this fault, and locating the exact one is a skilled work indeed. It will be best to contact any service technician. This is not a user repairable fault. If you wish to get some details, visit the site linked here.

Hello
Any ideas on how to eliminate the sticky residue from the front of my JBL LRS32P monitors?
Thx

well it sounds like you know what the problem is already, the first thing you need to determine is if the fuze is blown, jbl's are expensive speakers and usually there is an internal and sometime an external fuze, sometimes the midrange and tweeters are fuzed sepeataly. I'm ont familiar with that particular model, but if it not a fuze then most likely you have overloaded the high end speakers and they may have blown out, the high freqency drivers and not cheap and if they are new and under warranty you might have a chance to get new tweeters/horns free but if it is your fault e.g. too much power going in, then you will have to pay for them. You can get replacemdent JBL or other good speakers at www.martinsoundproducts.com they are out of Cleveland Ohio and you can call them when you get their number off the website..

You need to have the speakers re-coned. Unless they are really really good speakers this will cost you almost as much as new ones. A JBL authorized repair facility should be your next call. Replacing them is probably the answer

I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
The High-Pass control
determines the frequency at
which the main speakers
will start reproducing
sounds. If your main speakers
can comfortably reproduce
some low-frequency
sounds, also set this control
to a lower frequency
setting, between 50Hz –
100Hz. This will concentrate
the subwoofer’s
efforts to the ultradeep
bass sounds, while your
main speakers continue to
reproduce the mid-bass
information. If you are
using smaller bookshelf
speakers that do not extend
to the lower bass frequencies,
set the high-pass crossover
control to a higher setting,
between 125Hz – 180Hz.
With this setting, your main
speakers will not have the
burden of reproducing any
low-frequency sounds.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
Final adjustment and blending
of the low-pass and high-pass
controls may evolve over several
listening sessions. A good
starting point would be to set
both the low- and high-pass
controls to the same frequency
and adjust from that point.

Sound like the tweeter is blown, take to local jbl agent for service.
