They are mid Hi speakers.1st Open them and check if the mid speakers are ok maybe they are defected or the protection is open. Good Luck Toufic Malek

The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.

for pictures.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.

This how i repaired 2 of my 4 modus eights.

You can use any providing you can determine the max voltage in the device and the polarity.
If the capacitor in the unit has a wire out of each end and both ends have indents then it's a non-polar type.
Speaker capacitors for tweeters tend to be around 2uf.
The Voltage of the capacitor should be bigger than any voltage in the device.

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

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.

Tweeter no sound but speaker no problem


In the most general, basic sense, I would be assuming that this is just one speaker and not 2 with this problem, or 3 or more.
Only way to get the ball rolling is pull the tweeter from the cabinet, checking to make sure all wires are connected at the tweeter and inside the speaker.
If that is the case, then you would need to determine if this is the tweeters fault, or its crossover (thing that divides the sound into whats right for the woofer and what the tweeter wants).
If you have a multi-meter, you would disconnect the wires from the tweeter, set the meter to ohms and touch a probe to each speaker terminal. No action means burned out tweeter, 100% action means burned out tweeter, a reading slightly less than the rating on the back of the tweeter (for instance an 8 ohm tweeter would show anywhere from 6 to 8 ohms on the meter) means tweeter is good.
If you have no meter then take the tweeter from the good speaker and swap in place of the bad one, making sure you respect + and - connections.Its a little risky this way,since if there is something wrong in the speaker it may hurt the good tweeter..(the meter is the safer bet). If it works, then you need a replacement tweeter, if not the problem is either wire connections inside the speaker, or something is wrong with the crossover.

Hello........ looking for a schematic for Bose 501 series 3 speakers. I need to replace the fuse in line with the tweeters.... its blown & does not have a value on it (unmarked, quick blow, twin lead,...


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

Tweeter not working. Replaced it, but still doesn't work.


When you replaced the tweeter you should also check if there is any damage to the crross over network. It is possible that the capacitor , inductive circuit could have opened up. Remove and check. Check seperately with a good multimeter or use a 1.5 volt AA cell for testing the speakers. You can connect the speaker cabinet line to the battery and ccheck for voltage at the tweeter branch. Othere check the nettwrok and resolder or reconnect or replace. Hope this helps. Good day

Cuoul i replace the tweeter with any 1 inch tweeter other than acoustic research?


Providing you match the power and ohm rating of the acoustic tweeter yes. You could of course have an higher rms/watts rating than the original, but not lower. The ohm though must be the same. The only thing that might happen is that it might sound different to the other speaker, as the tweeter sound quality could be better or worse than the acoustic. Of course you could buy two and replace the other speaker one too!

I have floor speakers that i replaced all the speakers in it with 4 ohm speakers and i just bought a onkyo receiver n it gets really hot and shut off 1 time....i was wondering if there is a way to wire it...


Home audio is typically 8 ohms. If the speakers you used were designed for mobile audio then this would be why the receiver is overheating. You may be overloading the output

Tweeters????


Hi oddone

You may have a problem with either blown tweeters, or a faulty cross over, or both. If you have a multimeter, you can remove the tweeter, and check it DC resistance. They normally have their impedance marked on the back of the magnet. If not, you can assume they should measure 8 ohms. If they measure open circuit (high resistance), then they have failed.
A good speaker repair guy can often fix an open circuit tweeter as they often break where the very fine wires attach from the voice coil to the terminal. you can take a turn of the voice coil and reterminate to solve this problem. If the voice coils are burnt, they will need to be replaced.
If the tweeter meters ok, then you may have a problem with the crossover capacitors going dry. Generally they are 2.2uf to 6.8uf in value, the smallest cap in the crossover. If the plastic coating on them is split, or they look a different colour to the rest of the caps, replace them, if they sound "hollow" replace em, if you are not sure, replace em. other than that there is not alot more to look for with a speaker box tweeter Good luck and happy listening.

If you have any dramas, get back to me here and we can talk more about it.

My speakers sound flat with no highs at all


I am trying to work out if you have damaged the speakers and amp too.
Have you tried a pair of headphones on the amp? If they sound ok then your amp is fine.
Assuming it is, then speakers have what's called crossover units in side each of them. This splits the sound into three parts. Bass, midrange, treble. The bass is handled by the woofer's, the midrange by a middle sized speaker or or it's combined with a tweeter, which of course handles the treble.
Connecting a 1.5 volt battery across any of the individual speakers will cause it to pop if working. If the speaker then is not getting sound then the crossover unit is to blame.
When you look at the crossover unit, it will have coils and capacitors (non polarised) on it. The bigger ones deal with the bass and the smaller ones treble. If you find a fault say on the crossover of the speaker, for example no treble comes out of it. Then start by replacing the capacitors. Use the same value as on the capacitor and remember they fit any way round.
