these are great speakers they actually sound pretty good. they are 25 watts rms i hooked them up to a 40 watt ford stereo and turned it all the way up and they did not distort in fact it actully clipped the ford radio. i put these in old sony cabnits off of a boom box. i will eventually mount a small amp on the left speaker to make a portable stereo. The speaker's bass response actually was pretty good kind of suprised me for such a small speaker.

I read reviews on these speakers(I bought 2) that said they burn out easy,and a reviewer said he could push on the paper and get one to work.That happened to me on one of mine also.Thats a manufacturing defect,where the braid either is soldered poorly or comes apart at the voice coil.So I didnt listen to the bad reviews and I should have,because after 5 minutes of medium volume music(its supposed to handle 50 watts,and that's a lot,folks)one of the 2 I bought went bad.On speakers this small,I like the design,but they apparently have quality control issues.I bet I could return the bad one and I might,but its hardly worth the trouble.The one that still works is kinda buzzy with poor dynamic range.
They're cheap!But not really worth it if they were free.

I bought these got them really fast(thank you amazon) and was surprised they looked really good, installed them and one sounded good and the other was cutting in and out. when it did work all it did was squelch and pop. I exchanged them(the return process was very easy and fast, again thank you amazon). Got the next pair in and it did the same thing again one sounded great the other didn't. it wasn't my stereo( I swapped the speakers to see if I had a bad channel and it did the same thing). If I would have gotten two good ones with would be a totally different review.

If your looking for a great pair of speakers, think again.
But for the price, I'm satisfied.
All I wanted to do was replace a pair of blown door speakers on my 20 year old Ford Escort work car.
The fit right in, with no modification.
Billy Joel said it best, "You get more mileage from a cheap pair a speakers,
Its still rock-n-roll to me."

these are the cheapest speakers money can buy so far had them for a month and they sound 10000x better then my 20yo speakers that came with my festiva. If your looking for a replacement speaker for your beater upper and money is a problem get these they are not that loud and wouldnt recommend going too loud on these since they are dirt cheap. If your looking for a replacement for your 4inch speakers and you only got 20bucks then you wont be dissapointed. you can get 5 speakers for 25 bucks wayy cheaper then walmart.

Pros-cheap, sounds pretty good, decent quality, looks good, cheap cheap cheap!!!

Cons-might blow if you turn it too high, not for high end systems might blow once again,

For the price I paid for these individual speakers, the fit to stock was all but perfect. With just a slight trim to 2 sides of the left one it was a one step install. The sound quality given the price and the sorce, is adaquit. The speakers themselves were exactly what i was lookin for and i was glad to find them on Amazon.

Pros:
You really can't beat the price.
The speakers sound as good, if not better than, any stock speakers I've heard.
Did I mention the price?

Con:
Wait time. No star deduction for this because, (to be fair) they tell you before hand it might take weeks.

I agree with other 5 star reviews. It works well.and sounds good. I used this to replace the driver in a TOA F-10B "pyramid" loudspeaker whose foam surround had deteriorated. The shape of the frame was the primary motivation to buying it as it had to fit a routed cutout in the baffle. Even so I had to fashion a gasket to seal it due to a difference in the profile of the frame. No big deal. I tested it with a variety of music using fully professional audio audio equipment, as well as comparing it to an EAW UB-12Si (current price online = $343). I was very pleased with the performance, especially considering its low cost.

I don't know about others who say it failed. I ran it using program levels of several watts with peaks around its 50 W peak rating with no issues. If you put the rated average of 25 W using music program, I would expect it to fail from over-excursion from the typical peaks.in music, especially for low frequency (bass) notes. This seems to equate to the type of failures others have reported, i.e. breaks in the flexible leads connected to the voice coil. In this light about 3 W average (3.5 V rms) would be its practical limit with music and this was about the maximum average level I used when testing. This allows some 12 dB of peak headroom which corresponds to its 50 W peak rating. For more dynamic music the input level would have to be lower to avoid exceeding it's peak (excursion) rating to avoid failure.

I suspect this driver was rated using a sine wave (typically 1 kHz) because the peak in a 25 W (10 V) sine wave is 50 W (14 V). There is nothing wrong with the rating if one understands it implications for actually using the product.
