Question about Jensen M-1 Speaker

Open Question

Blown "S.T.A.R." tweeter on the M1

I have a blown "Symmetrical Throat Apex Relief" driver on one of my Jensen M1's. Can I get another one somewhere without paying an arm and leg? I would prefer a new one rather than getting one off e-bay. Should I get 2 to replace the one in the other speaker as well? Is there an upgrade {aftermarket or Jensen} to this driver that matches the acoustic characteristics of the M1? The markings on the blown driver are D04-0090 and 8H745. Any help is appreciated Tks.

See if there's a reset button, usually behind the faceplate. Try that.

SOURCE: someone replaced the subwoofer on a jensen jps12

It can probably be fixed but it might be cheaper & quicker to just replace the amp.
Here's a little tip for you for next time.
A lot of people say a sub can be "too big" for an amp & cause it to fry (burn out) but that just isn't the case.
You can put a 50 watt amp on a 1000 watt sub & it will play just fine for years to come.
A subwoofer does not pull power from an amplifier, the amplifier puts out what it's got & the sub can either handle it or not, it's as simple as that.
In the case of a higher wattage sub & a lower wattage amp, the sub will handle it just fine.
Now, where most people mess up is the ohmage of the subwoofer vs amp.
Different subwoofers & amps have different ohmages & those ohmages come in every size ever made, so the wattage of a sub or amp has no effect on the ohmage of the product.
In case you don't know what ohms are....
Ohmage is pretty much like back pressure.
Let's do a little example here,
Let's say you need to blow threw a tube & create a nice steady stream of air (kind of like an amp pushing power threw a sub).
How's it going to work if you try blowing threw a (lower ohmage) coffee straw?
At lower levels it will be easy, but as the level of air (wattage) goes up, the harder it becomes & eventually you end up straining trying to force air threw that straw (subwoofer).
Now same scenario but this time you are blowing threw a (higher ohmage) paper towel tube.
Now you end up trying to push so much air with such little resistance that you end up straining & winded trying to keep the pressure up in the bigger tube.
You need something in between. Something that offers enough resistance but not to much. That's what ohmage is between an amplifier & a subwoofer.
Hope this helps you have a better understanding.

Have 2 jbl 615 get good base and sub but neither tweeter playing


You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.

I lost the treble on both Alesis Monitor 1 speakers. The treble is good on the amp output toward the speakers. I'm thinking they went out one at a time and I didn't realize it until I lost the...


It's probably blown tweeters. But if you want to spend the money on a hipshot guess, try to find the the crossovers somewhere first; then find the readily available tweeters if/when that doesn't work out. Google "alesis monitor one MK2 tweeter".

You could test the tweeters by just removing one non-functional tweeter and wiring it directly to the speaker leads and with REALLY LOW volume containing NO BASS see if it makes any sound, which would prove it does/does not work.

Going forward, if the speakers sound stressed at high volume - THEY ARE. Too much power or too much distortion (overdriven amplifier) will kill speakers.

I have no sound coming from the tweeter in my b&w 602


Probably blown, tweeters are much more fragile than lower frequency drivers. If you know how to use an ohmmeter properly you can test it for continuity if it's a good quality meter (cheap ones can blow it out themselves in testing).

How do i tell if my problem if the high freq diaphram or the cross over


The crossovers in professional speakers don't fail that easily. It could be a blown tweeter. To confirm remove the metal grille-- remove the screws of the Horn Tweeter -- remove the cable connectors on the tweeter terminals ( Red and Black wire ). Now if you have a multimeter put it in Ohms range and touch the probes on the tweeter terminals-- It should show a reading betwwen 4 to 8 Ohms depending what is written on the back of the tweeter magnet. If you do not have a Multimeter you can take an ordinary cell/battery ( 1.5v ) from a TV remote and touch the terminals of the Horn Tweeter with the battery. + to the tweeter + ( a small red dot or mark will be there on the tweeter ) and -- to the tweeter -- . When you touch the terminals or give 1.5 volt supply the tweeter will make a scratching noise.
If you do not hear the scratching noise - it indicates a blown tweeter coil and will need replacement.See link below for spares:-

But if it does, you are in trouble and will need professional help from a electronic technician.
Could be blown HF Amplifier, suspect the crossover last. They seldom fail.

Is there anyway to fix a blown Bose Speaker (201)?


The only 2 solutions are: 1. Just find an equivalent driver to replace. Re-wire new driver speakers into the enclosures. The old 201s may have had decent drivers (although probably paper cone) for back then, but now just about anything will sound as good in those particular cabinets.
2. Call Bose and exchange them for current 201 speakers (higher clarity more powerful). Bose will give you about 30-40% off I believe on a series 5 model. They now pay for inbound and outbound shipping as well.

Blown tweeter


Remove the front grille, and speakers are accessed easily. Stick a little hook tool in the mesh, and give a tug. It is press-fit so dont try to pansy it!

The tweeters in my yamaha NS-515F have blown. Any ideas where i can purchase suitable replacements?


http://www.partsexpress.com is a popular source for loudspeaker components.

Also, are you sure the tweeter's blown, and not a crossover component?

www.mouser.com carries many electronic components that could be used in crossovers.

TweeTer Not working.


The only way I can think of to check is to disconnect the leads to the tweeter, then check resistance with an Ohm-meter...no reading means dead speaker.
