Summing up L & R line-level for dual subs

I have dual subs and I'm taking the line-level signal out of my Lamm LL2 (pre) second set of L & R outputs. I'm setting up the subs following Earl Geddes approach to multiple subs setup, that calls for the summed-up mono signal played by all subs, and each sub set up to play a different range.

I've seen Y-type connectors suggested as a way to sum-up L & R. Would that work?

Thank you!

Also stated in the last paragraph of the first reply. ;-)

Probably too well. Combining the L/R out of the Lamm will probably sum the output to the main amp/speakers. Result: No stereo.

If your subs have L/R inputs, you should connect to them independently and let each sub do the summing. Otherwise, you need an isolated or buffered Y connection.

Point taken, Lewinskih01. I do tend to be very brief, so it is good that others, like Al, take the time and patience to explain in more detail.
