Logitech Z623 speakers and Computer Speaker Research Questions




I have a set of Logitech Z623 computer speakers. This is my second set. The first set that I had lasted me two years. I have had this set for almost two years now. The Z623s are hooked up to an ASUS Xonar U7 external sound card via shielded RCA cables. Both today and a few days ago, I noticed a static type sound when turning on the speakers. I did not see the speaker light flicker like what happened with my first Z623s, but I am concerned that the speakers are going bad on me. In the last 30 minutes I have adjusted the master volume on Windows from 100% to 50% and moved the RCA cables away from most of the other computer and power cables. Also, just in case this may be a factor in my problem, I am using updated ASUS Xonar software designed for Windows 10.

My Questions are as followed:

1. I use my computer almost every day. Primarily the speakers are used for music and gaming. Am I just wearing out the speakers or could their be a defect in my computer speakers? I ask this because I am noticing static at about the same time as when the other Z623s started having problems problems.

2. Has anyone else been having problems with their Logitech Z623s going bad after a couple of years or has this model been known to have defects?

3. I realize that I may have gone overkill with THX-certified speakers and that there are good non-THX speakers out there. If it is in fact my computer speakers going bad, what would be an appropriate 2.1 computer speaker set to buy that cost $100 or less that would work well with both music and gaming?

Thanks in advance.

I'll try to answer your concerns to the best of my ability.
1. Yes your speakers can wear out in time, if your last model shown defects after two years and this one is repeated, it's definitely because of one of the following reason:
-Your environment affected the adhesives
-Voice coil being damaged
-And I don't know if these are inside but there are some Alnico magnets in most of my speakers, and sometimes, my mechanic would "re-magnetize" it.

2. You can check the reviews here:
From what I've read, the speakers were known for not lasting long, that's all! You're not the only one here!

This guide might help you for your next speakers. I personally liked Logitech's speakers for their quality but be sure to read the reviews. They can be helpful for you.
