Summing up L & R line-level for dual subs

indeed, Kal. However, let me point out your posts tend to be criptic and I oftentimes don't find them helpful, despite being right on (which, like in this case, I realize after someone else has gone through the trouble of explaining). This is why Al's contributions are so valuable to many here: super-knowledgeable, takes the time to look into the question, and takes the time to explain.

I've been following this thread because after years of using a single balanced out from my Velodyne SMS-1 into a Y to two HGS-15s, I discovered that the SMS-1 provides unbalanced outputs for controlling up to three subs. Velodyne recommends a Y from each of those outputs into the LR inputs of each sub.

Years ago, editors at SRI would spend hours going over our papers teaching us writing skills we hadn't leaned in doctoral programs. But by the time I became director of a research center, cost cutting reduced the staff of editors.

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.
