250ti left and right speaker sound very different

[limpan]

Hello! I`ve had my 250ti(the first version) speakers for 7-8 years and have always feelt like there`s quite a big difference between the left and right speaker. First I thought it was the room but now I have realized that it must be something else. Previously I used the different crossover settings to compensate for the differences but now I would like to fix it once and for all. I`ve switched the left and right on the amp to eliminate that it would something with the signal to the speakers.

It`s mainly the 044ti that sound way different compared to the other speaker(very dull compared to the other). I`ve diassembled the 044ti to check if it was the foam pad but it`s the same issue even with a new foam pad. The only thing left would be the crossover. Maybe some component have failed or if a solder joint is broken.

How can I check the crossover and what kind of equipment is needed? It seems to be a big job to remove the crossover from the speaker. Anyone that have experienced similiar issues?

Have you done any measurements? that will accurately tell u if they are indeed different and at what frequency/driver.

That sounds like a good way to confirm how they perform. But that’s something I’ve never done before so please share some information how that can be done in a simple way without any expensive equipment.

There are many ways to measure your speakers at several price points from virtually free to spending thousands on dedicated equipment. To gather accurate measurements takes a bit of study as well as having the gear.

To make simple comparative measurements between two speakers, you can use an iPhone or iPad with the built in mic and a $10 app from Studio Six Digital. https://www.studiosixdigital.com

On a separate topic, have you exchanged the two tweeters, moving the left tweeter to the right tweeter location and vice versa to see if the changes follows the tweeter?

I have’t tried switching the tweeters but I will try to do that this weekend.

CC'd this animal about 10 years ago, Resistors are all upside-down. This ought to help.

Since you only care about the difference between 2 speakers you can probably make do without fancy measurement microphone. Look up AudioTool for Android. You then connect your phone audio output to your amp and it will generate a frequency sweep and measure the response from the speakers. cost a few bucks but it is worth it. Alternatively, you can use REW for the PC but the process is a bit more involved and you need a microphone that connects to your computer.

If needed I can spend around $100 to get required software/hardware but as you mention I will just do this to evaluate the difference between the speakers so maybe not required to spend that much. I have a Rode video mic that I could try. Or what do you think?

When it comes to the crossover, have anyone experinced any issues that could cause this? All the cables, caps, resistors and other components looks visually ok from what I can see.

If you have a Rode, it is more than good enough. Just download REW and do some measurement. It is free software.
