Uneven speaker volume output

First of all, make sure your balance control is centered. ;) -- I'm not kidding -- I once spent a half hour trying to figure out why my left channel was louder before I realized that I had inadvertantly changed the balance. Then, check to make sure you have your speaker cables hooked up correctly so both speakers are in phase (negative to negative, and positive to positive, on both speakers).

Your post contains a typo, so I can't tell if it is your right or left speaker that is louder -- I'm going to assume the right channel is louder. Switch the speaker cables and see if the left channel becomes the louder channel - if so, the problem isn't your cable, speakers or placement. If the right channel stays the louder channel, then the issue is either the speaker itself, or speaker placement.

Assuming the problem is not the speakers or speaker placement, switch the right and left cable on the inputs to your amp (if using separates) or on your music source (if using an integrated amp or receiver) and see if the right channel stays louder. If it does, then you've isolated the problem in your amp/receiver. It the left channel becomes louder, the problem is your input source.

Now, at least, you know where the problem is isolated.

Glad to help, and glad you've found a work around while you figure out the culprit. Happy listening.
