If you place an ohm meter across the capacitors, the ohms should slowly drop as the capacitor charges. You can check continuity of the coils with continuity function of the multi tester. is a good source for quality components.

SOURCE: sound went limp i think it the crossover

Define limp. No highs or no volume?

Logically, what one thing would affect both speakers? Logically, how would a crossover failure mute anything but the tweeter?

So, what happened just BEFORE this problem appeared?

I'd look at the electronics.

many amplifiers protect against a short and against an open. They are looking for speaker resistance within limits. Your wire to the speaker may be too long or too thin. You may have hooked up more than 1 speaker per output causing too low resistance. Keep your wires short as possible and use 12 or larger gauge wire if you are driving large wattage speakers. Check the ohm rating on your speakers and compare them with what the amplifier calls for. Hope this helps

SOURCE: Hello........ looking for a schematic

Did you find a solution? Dunno if it's much help, but I just today picked up some 501s - Series I I think - ugly heavy brown material grilles - but with a manual! No fuses in these, but booklet recommends installing your own in-line fuse holders (!?). Specifies a BUSS AGC-3 fuse for amps under 50wpc; or a MDL-2 fuse for amps over 50 wpc. Can be placed is series with either or the two signal wires. Very strange.... Robin

Why don't you just ask Bose what rating the fuses are? A lot of manufacturers just don't like supplying circuit diagrams, but they might tell you about the fuses.

Does the user guide say anything about the fuses?

You were on the right tracks regarding how much of the signal the tweeter receives. I don't know how much, but it's a small percentage of what the woofer gets.

Hope you find the correct answer soon.

Why is there no bass?

Not much info to go on here, but my thought would be you have blown the woofers in the speakers, or the crossover in the cabinet, that separates the highs from the lows. . If you can touch the woofers with your hand, spread you hand wide over one, and try to move the cone. If it makes a scraping sound , the speaker is blown. If not,the crossover is probably damaged.

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.

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:

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.

I have peavey speakers Model #112H.Both horns went out,,i'm not sure what caused this. is there a component that i can replace,or just replace the horns completely?

If they are seperate speakers and both "horns" have gone it won't be a part common to both. The most common way of blowing both speakers is to have the amp too loud. The real cause is often connecting a high powered amp to low powered speakers.
As you will have to replace the horns if they have blown, disconect them from the circuit and apply a 1.5 volt battery to the terminals for a split second. (+to+ etc) It should 'pop' if it works. If it does it will be the crossover that has gone.

Internal wiring schematic for a JBL 4311 WX-A

the conductor xxx\blk is the minus or black( from speaker) the outher is positive\red pin from speaker) the woofer is bigest speaker inside is connected on the crossover at low output, tweeter at high output, if you connect wrong you can burn speakers and crossover, you can test with very low volume on amplifier.

1st connect low to woofer, it only her low freq below 500Hz like drums and bass, if connect on med out the speaker is working as handpocket old radio audio. if connect on high the speaker is like no audio out. (the woofer take about 60-75% of amp power).

2nd connect the midrange at mid output you can listen to human voice cristal clear. if connect on high output you listem like esteric female shouting.

And connect the tweeter at the empty output

Take particular attention on polarity terminals, if you exchange the polarity you have a moofle sound traped inside of speaker, and some structered box noise who may open the box panels in future.

No sound and smells like burning

There are a lot of folks who've had power supply issues with this sub. Typically, the large resistors fail, which takes out the capacitors.

If you know how to read schematics and replace parts, then these might be helpful to you:

Here are the two pages of schematics from KLH. I wrote to their techdepartment and explicitly asked for permission to share them here.

Here's the lower board, which has the power supply:

I have a xenyx 2442fx mixer and ep2500 power amp hooked up to 2 1800x subwoofers and 2 1520 pro speakers. i am using a peavey xr 684f powered mixer to power my monitors. i would like to add another power...

You would need a 2 or 3 way crossover, depending on whether or not you biamp your tops. Simply go out of your main outs on the mixer into the input of the crossover. Go from the low output of your crossover to your low power amp input (subs), and the high output of the crossover to the high power amp input (tops). Then go from your outputs of your amps into the speakers themselves.

I need replacement 8" drivers for my Peavey PRM 308S Monitors. What would you recommend?

You have to use original manufacture parts if you want the orignal sound and specs. The crossovers and design of the speaker enclosure is matched for the speaker drivers. Start at the link below.
