Hi all,

I'm using z-2300 speakers with X-Fi XtremeGamer Fatal1ty Pro. Subwoofer sounds great, but sattelites is total crap. I will change original satellites to better speakers later.
I found x-fi modding tutorial on this site before several weeks, so I modded my x-fi: 1x ad8599 opamp, removed mute trasistors, removed all jamicons caps (changed to panasonic's FM, rubycons ZA..). Now, is time to mod my z2300 subwoofer amplifier The problem is that I dont have enought experience for this. So, I need your help. I will change all capacitors to panasonic audio caps and I need to change all opamp too.
Can I change all JRC 4565 opamp's to LM4562 or AD8599? Is it works?

here is some photo's:

I dont think it's worth it. The Logitech's internal crossover is designed for the particular satellites. Ive tried attaching a pair of nicer satellites/bookshelf speakers to the Logitech Z2300 and the midbass sounds VERY muffled (does not sound like that when attached to a standard receiver). I think the crossover inside the Logitech overcompensates electronically for the stock satellite's midbass inadequacies so the signal going out to the satellites is heavily equalized.

bad news I agree with your answer. But, maybe there is a chance to bypass internal crossover ? somehow

This is very interesting. Does anyone actually know what is inside of the Z-2300 amp?
I have got the same speakers, but with different satellites (AIWA SX- LEM70, borrowed pictures below). I would be very much interested if there is anything we could do to improve the sound.
I must admit that even with those crappy Aiwa'a the system sounds better than with stock satellites.
I was thinking of upgrading the cable from subwoofer (RCA to plain cable) and/or upgrading those satellites, what are your thought guys?

Bump. I was blessed enough to get these speakers from a friend today, and they sound great, although the satellites are a little lacking. I really don't think the sub is lacking, but the satellites could use work. Parts-Express has some useful stuff. I also have a 500 watt 18" sub lying around, but the Logitech bass amp is only pushing 120 watts. It would probably be more than enough, but I would want to get a little more out of the 18. How about just trying some decent bookshelf speakers from Craigslist and seeing how that goes?

The logitechs sub driver can be changed, loads of people have swapped out the sub driver search youtube, also seperate tweeters can be added to the satilites.

Thanks. I looked on Youtube, and someone is using some JL subs. I am currently watching some 8 inch JL subs on Ebay now. As for the satellites, I think i will go with Craigslist if I care.
