I see its een commen problem.

Do you have any idea?

SOURCE: bypassing the 150 watt blown amp with passive crossover

3/4 update: i bypassed the 300w amp on my first ovtr3 with a cs3006 crossover i purchased on ebay. the input wires at the base of the speaker were connected to the input of the crossover, the bass output of the new crossover was connected to the yellow/yellow-black lf+/lf- wires that used to leave the old 300w amp. the high freq output of the new crossover was directly connected to the leads coming from the speaker's tweeter (running the midfreq outputs from the new crossover to the input of the speaker's old crossover is no good, since the midfreq output of the new crossover would rolloff and provide little high freq to the tweeter). The mid-freq output from the crossover was connected to the input of the old crossover that came with the speaker (alternatively, i could have wired the mid freq output from the new crossover directly to the midrange speakers, but i figured the old crossover might have had some characteristics that would have been helpful. the result is better than i hoped for! true, the bass is not quite as floor shaking as before (and you need an amp that can boost +5-+10db below 350Hz and rolloff the boost above 350Hz), but the end result is more than satisfying and gives these speakers new life. I am using a Sony receiver that puts out around 200W for the front speakers.

SOURCE: infinity 3.5c , 2 powered Woofer 5.25" suddenly no sound.,

The woofers on my 3.5c stopped working, but with mine the light was off. I unplugged it and left it for about 24 hours and then plugged it back in and it worked. No idea why. It's happened twice and each time takes at least 12 hours or a day or so before it'll work again, just unplugging it for an hour won't do it.

It seems like both times the problem started when the speaker got unplugged without it being shutoff first, but I can't confirm.

But if your light is still on it's probably a different problem. With my 4.1t towers when the light was on but there was still no sound it equated to numerous fried amp components which cost about $150 for repair.

SOURCE: Infinity Entra Sub 150 no sound or power

I had the same problem. When I opened it up, the fuse was blown, and it was a pain to find the fuse it needs (3 Amp, 250 V slow-blow fuse, 5x20 mm). Also, the 2 large electrolytics (big purple things near the amp) and one small capacitor were all blown. For 4 fuses, bought seperately from, and the 2 electrolytics and 1 capacitor, it cost about $20, plus almost 20 more in shipping, which still isnt bad considering the original price of the sub. However, the tricky part is that you have to know how to use a soldering iron to take out the old components and put in the new ones.

SOURCE: Infinity 2 overture speakers- 1 wasn't working so

Verify that the bass levels are set the same on each speaker. If they are and the problem occurs on all program material, you most likely have a bad driver or amplifier in the speaker. One other thing to verify is that the balance or output levels of the left and right main speaker outputs are set equally on the receiver.

Good Luck,
BB

Open it up and see what is in there! You might find a fuse blown. It might have just blown, without a fault, if you are lucky. If not check out the part numbers on the amp board. All semiconductors numbers, then put the numbers into google. You will soon find out if they are obtainable!

The speaker has a low power output


The output of a speaker primarily depends on system design (obviously) However, perhaps you have sourced a replacement or 'upgrade' speaker for an existing system. In that case, perhaps you have an impedance mismatch. If your amplifier is designed to drive, say, an 8 ohm speaker, and you connect a speaker of 16 ohms impedance, then your sound will be softer. On the other hand, you may have connected more than one speaker to one power amplifier output. If you connected in series you add the impedances. If connect in parallel you work out the impedance using this formula:
1/Answer= 1/Speaker A impedance + 1/Speaker B impedance + 1/Speaker C impedance etc. So if you connect three speakers in parallel, each of 8 ohm impedance:
1/Answer=1/8 + 1/8 + 1/8 = 3/8
3X Answer=8
Answer = 8/3 = a little less than 3 ohms.
Reducing the load like this makes the sound louder, but risks distortion or even damage. Check your manual for amplifier tolerances. Cheers, Don.

My WHARFEDALE DIAMOND SW150 SUBWOOFER does not work. the light (red) comes on when connected. but no sound. I've tried direct from speaker and from receiver connection. doesn't work. Any advice


After finally finding the circuit diagram for the Wharfedale SW-150 sub woofer, I've managed to identify and fix a fault which has the same symptoms as yours.

The problem was with the largest of the two relays (Relay 1 in the attached photo).

wharfedale-diamond-sw150-subwoofer-p251q2jbxgw5dhyonjje5nyi-1-0.png

The circuit has two power rectifiers, the first rectifier provides the small current for the system to operate in standby. Relay 1 is normally closed and this turns on the secondary power rectifier that powers the amplification circuit.
Relay 2 (smaller and black) is used to prevent the speaker from popping every time the auto-power switches on/off, it uses a delay to allow the amplifier to stabilize before activating the relay which connects the amplifier to the speaker.

On my system the power LED was lit, but the little click that happened about 2 seconds after power-on, was no longer heard. The little click that was missing is the sound of the smaller relay connecting the speaker. This relay was not activating because the amplification circuit had not been powered.

The larger relay does not need to activate to turn on the amplifier, as it is normally closed, meaning the the default connection state is to provide power to the amplifier. The relay is only used to disconnect the amplifier when the auto-off feature kicks in (or the system over heats). I could test this relay was clicking by connecting pins 1 and 3 on the temperature switch connector.

So the relay was not connecting properly in the closed state. This is what the relay looked like on the inside.

wharfedale-diamond-sw150-subwoofer-p251q2jbxgw5dhyonjje5nyi-1-1.jpg

On the left you can see how blackend with carbon the contacts are. The contacts on the right are how they should look.

This is caused by a design problem. When the auto-off function occurs, the relay activates to disconnect the amplifier. As the circuit disconnects, these contacts arc, which causes the relay contacts to burn out. It is usually standard practice to include a small arc suppression circuit with relays, and as far as I can see, this circuit does not have one.

For the fix, it only needed this one relay replacing. I purchased mine from RS components in the UK. (This one is clear, so you can see the arcing when the relay activates)
DPDT PCB Mount Non Latching Relay Through Hole 24V dc

If someone can figure out a suitable hack to add an arc suppression circuit to this, then please let me know. Until then I am disabling the auto-off feature and manually powering off the device. This should extend the life of the relay.

The circuit diagram is available on this other fixya question:

This is a 3-way speaker; specifically which speakers do you hear something from and which speakers do you hear nothing from? If the woofer amplifer is blown, for example, you will hear nothing from the woofers, but will hear sound from the midrange speakers and the tweeter.

Do not know how to connect my kappa 60.5cs to my pioneer cd player do they have to go through an external amp?what do i do with the power plugs on the oppisite side why are there 2 per speaker


You need to run RCA cables from the CD player to the CD or AUX input on your amp / receiver unit. If you have a standalone amp, you need some way to control the volume. Basically, if you have a volume control on the front of your amp, you're OK. If not, you should also have a preamplifier that the CD player feeds first.

From the amplifier, then, a single pair of speaker outputs feeds a single pair of inputs on your speakers. The reason for two jack sets on the speakers is for "bi-wiring" or "bi-amping", not necessary for basic stereo reproduction.

So -

CD red/white RCA out -> preamp/receiver red/white CD/AUX input. Amp speaker output (red + / black -) to one red/black input pair on the speakers. An input on the speaker is side by side...

Keep the red to red, black to black when connecting the speakers, or you will wind up with poor sound and weak bass.

Why does the red light click to green without the speakers on?


That system responds to signal input, ie an electrical signal present on the input, in order to turn on the internal amplifier. If it is turning green without any input from the source, it could require service. It may be responding to static electricity...

The speaker should go to sleep after ten minutes or so, turning from green to red again.

Is there a on of switch and is the green or red light to be on


There is no main AC power switch on the BU series; it's in standby mode whenever it's plugged in.

When playing music normal LED color should be green. After no signal for 10 minutes or so it will turn back to Red (Standby)
