The inside part of a speaker

[Guest]

Hello, I have an old Sony home theater system and one of my speakers are broken. I want to replace the inside part of the speakers as shown in the photos but I can't find the same model on the internet and I thought I could find one of other brand. But I don't know how to search, how is it called in order to search of it.

Try Parts Express for a replacement similar to what you have.

Speakers are mainly comprised of woofers, tweeters and crossovers. That one looks like it uses a combination woofer / tweeter.

Believe it or not, that is actually called a driver. To replace it you need to know its size, Impedance, Power handling, frequency response, etc. Sony may be the only place you can find a match.

Here's a couple of drivers I found by googling 2 x 3.5 speaker. (based on your pic, it looks like the standard 2" x 3.5" size)

As clarkjd mentioned, that particular part inside the speaker is actually called a driver and the specs have to be as close as possible for best results. The one on ebay is 4 ohms, 3 watts. The one on Amazon is 8 ohms, 10 watts. Try to find markings on your driver and google the numbers/codes to see if you can get specs. Maybe the speaker cabinet or amp cabinet has a label or you can just google the speaker system's model number to find specs online. You need to know the ohms/wattage of that single speaker specifically, so "total" watts of your sound system is not useful. You may have to do the math. I should also back up and ask if you're sure that the driver is the problem. Is it buzzing when you play music? It does look like it's torn in the upper left corner based on your pic and buzzing is a symptom of a torn driver cone (note you will still hear audio, buzzing/distortion is extra). Did you try that speaker on another output to see if the problem moves with the speaker? If it works in another of the amp's outputs, then it's not the speaker that's the problem.

I agree that it looks like a small tear in the speaker surround in the upper left hand corner. You may be able to repair it with some tissue paper and liquid latex (that will dry once applied) or perhaps some silicone caulk. Just cut some tissue paper slightly larger than the tear and overlay it onto the speaker cone and metal housing and paint on some liquid latex. Don't make it too thick or it will affect the resonance of the speaker, but I have made repairs like this before.

If you can't find exact match, and can afford - replace the other driver, too. This way you will get uniform sound from both left and right speakers.
