Hi All.
So i'm trying to fix up my Logitech z-2300 2.1 speaker setup that i bought ages ago because i have an affinity to it. I have an issue that i need to fix and am looking to get some input on it. The issue is as follow:
The rubber surround on one of the satellite speakers cracked at some point, i'm assuming from temperature or overuse. I ended up cutting out the cracked parts, but the speaker still crackles with the right notes/tones/volume. Can someone point me in the right direction of places to buy decent, good value rubber surrounds, the right adhesive to apply to it, and tips on the process?

They use some type of 3" full range driver for the satellite speakers. They used to use a Tang Band W3 driver in the Z-5500 but I believe in the Z-2300 it is some kind of cheaper unbranded clone.
The crackling sound will be from the voicecoil rubbing since the cone/voicecoil is no longer properly supported/centred once the surround has torn.
Your best bet is probably to buy a cheap Z2300 system from Ebay / Craigslist / FB marketplace - damaged in some other way if need be - and build one mint functioning system out of two average ones. On ebay there are also some sellers in China who will sell you the entire replacement driver (search "logitech full range") - I don't know if these are counterfeit or factory seconds or if they are an exact drop in replacement or just vaguely look similar, so buy at your own risk.
You can replace the surround with a generic surround replacement kit but honestly it's not worth it. You're going to have to take a gamble on buying a 3" rubber surround from ebay china, and may need to cut it to size as a 3" driver requires millimeter size accuracy. Even if you are successful in the replacement, the generic surround may give drastically different sound to the original one. I would only bother replacing a surround on a large woofer (8"+) and even then I'd do both woofers in a stereo system so they match. I think you're going to get a better result parts raiding a second hand system or trying to source an entire replacement driver (for best results replace both drivers so they are matching).

I think these speakers are actually a lot smaller. The OD of the cone is 1 3/4 inch from what i've measured
Yeah, it looks like there's individual speakers off of ebay, or whole systems. I'll look into those and see, since it sounds like it wouldn't be worth it to try refitting another surround on it.

There are good 3" full range driver replacements. If it's glued in place however it would be a mess to replace.
Wait, so how is the size measured on these drivers? The width of the whole driver taken out of the housing, or the cone width?
I was last week here buying a surround for a friend's Sony 8'' speaker but I think they have only 5'' onwards. I've used contact glue and is working fine.
I've seen also small speakers for 20-30€ there that could fit.
I buy rack hardware & speaker grilles there.

Also if you post measurements yourself, eg the distance between the mounting holes and other things, in the full-range forum you should get some recommendations.
Size is indefinite. When I was a wee tyke you measured the centre to centre on the mounting holes. Now things are a different. Judging by your pic, you have 3” drivers. Measure the basket size and of course you must find out if they are glued in place as Allen says. If so, say bye bye.
the aliexpress link for the original drivers in that blog seems to still be active. While not all that inexpensive, this is no doubt going to be the easiest solution for the OP, especially if he's trying to repair/restore these to their original condition for sentimental purposes.
If the OP would like to save a few bucks and isn't totally concerned about originality, then using that blog tutorial as a guide to substitute a different driver, this opens up plenty of possibilities for retrofitting some different drivers. Parts Express and other sites have a lot of small driver options, and I'm sure the OP could find one that's a nearly perfect drop-in, or one that could be easily modified to work.
This dayton driver looks like it would be a perfect drop-in:

This Tectonic looks like it would be very close to a drop-in fit:
Tectonic TEBM46C20N-4B BMR 3" Full-Range Speaker 4 Ohm
This Dayton looks like it would fit with some work too:
Dayton Audio DMA70-8 2-1/2" Dual Magnet Aluminum Cone Full-Range Driver 8 Ohm
Lastly, if you can find replacement foam surrounds in the correct size, you could re-foam them.
