Mixing LFE and LR for stereo subs

[jf4828]

Any suggestions on a practical way to mix LFE and LR signals for stereo subs. I'm meshing a pair of UM18-22 with DIY dipoles and would like to maintain stereo bass. I'm using miniDSP for bass EQ duties but only have 2 channels in on the DSP. Is there a good method to add LFE to the signal. I'm using single ended connection for LR and LFE signal. I plan to use dsp presets to toggle movie and music modes. Is a y connector acceptable if I attenuate outputs by 6dB or is there a better solution?

I don't really want to spend time justifying stereo subs at 50hz, I know this will sound stupid to some....

Mini 2 channel stereo mixers are available. You could use your left / right sub signals on one stereo input and use a y lead for your lfe signal to the other stereo input.

A simple "Y" cord may not work properly.
This will explain "wye" not, and how to sum signals correctly:
Why Not Wye?

Thanks, this is exactly what I was looking for.

I've thought about a small mixer too or just getting 2x 2x4 miniDSP in lieu of the 4x10 (only has 2x analog in)
