The FLAC's are mono and most applications will obey that it is mono and play it on both speakers. Everything I have tried it on plays on both. Transporter -> G68, WinAmp to 5K's, Audacity to Laptop Speakers all output on both speakers.

Make sure your Meridian is in Direct Mode when testing.

It may be nothing but worth checking into why it's only playing on left as it may be hint of something going on that should not be.

Some day I will clean these up and make a full set in stereo and at a couple frequencies.

Did you get past the 96dB attenuated one?

If you think listening to music is fun, try learning an instrument.
