I've got an old TrueSub that has never been turned off and I bought it used nearly 15 years ago. The same goes for my old Vandersteen subs and my current Velodyne SPL-1500Rs that I've had on since I bought them in 2006.
I just checked and the Velodynes are on and cool as a cucumber. It must have something to do with the circuit used and the amp that Gallo uses.

User's manual 63-SPLR Rev F Jan07
"IMPORTANT SAFETY INSTRUCTION
14. Nonuse Periods -- The power cord of the subwoofer should be unplugged from the outlet when left unused for
a long period of time."
or---
"CARE OF YOUR SUBWOOFER
During normal conditions, the subwoofer may be left on continuously without any problems.
If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel."
Somewhat contradictory statements here, and both with ill-defined terms of "...normal conditions...", "...long period of time" and "...extended period of time". It may be interesting to see what actual definitions Velodyne has for these; if any.
Since it's doubtful that these or most any consumer level subwoofers are tested and listed by a NRTL (such as UL), I doubt these instructions would be acceptable as-is without more clarification and specificity.
The issue of "standby trickle current" is not unheard of for home appliances. I'd say any modern TV with configurable settings and even my dishwasher have standby trickle current, and both are UL Listed.
And that's the potential catch with non-mass produced audio equipment. They aren't subject to safety testing against Standards that all other competing products may be subject to.
Awe-d-o-phile,I tried them in just about every way possible.On sides lowered the soundstage.The best was positioning them with the binding posts adjacent to one another.Bottom one with base down,second base up.This allows the shape of the cabinets to be continuos and yielded the best sonics.

I should clarify:Top speaker with binding post down.Bottom pair with binding posts up.Also keeps jumpers short.

you never know with some designs. My fried has a Yaesu transceiver that runs via an external power supply. Many people have made the mistake od turning off the power supply instead of the radio and friend the control board.
