In Reply to: RE: Be sure to unplug the sub when not in use. posted by Awe-d-o-file on June 08, 2015 at 07:44:19
No, it's their latest sub, fires horizontally. Shaped like a barrel, driver at one end, controls at the other. You just may remember the tech, Brett Mullins, who is adamant that ALL powered subs should be unplugged when not in use.

I worked for Brett for several years and still talk to him. Their downfiring unit was also cylindrical. I always liked their subs. This one was sealed.E

The switch just puts the sub in standby. After my two died, the standby lights were on, the fuses were fine ... but no sound.
As noted above, my tech, who's been in the business a long time, says you definitely shorten the life of ANY sub amp whose "off" switch simply puts the unit in standby. Me, I wouldn't know but he was pretty persuasive :-)
I would challenge that and say the problem the tech experienced was with specific amps or specific designs.
I've got sub amps here in service 10+ years and I keep all mine in "auto" mode where they turn themselves on when they get signal - I've had no issues.
Of course, a tech only sees amps that are regularly failing so he may start to thinks he's seeing a segment of "all amps" but really he's seeing the stuff that most frequently comes in for repair.

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.

I can't believe you can't design a powered sub so you don't have to unplug it. If it needs to be turned of there should be a switch that doesn't just put it in stand by. But still I use a Sunfire amp with no on/of switch So it's on all the time unless it's unplugged which I rarely do. he amp is on for years t a time with no problems.

Check out Cambridge Soundworks. I bought an acoustic suspension 12" power sub and it has been plugged in on standby since I bought it 20-years ago. It still sounds just fine. In fact, I leave my preamp, phono stage, and power amplifier plugged in and turned on 24/7. I haven't experienced any problems.

We never unplugged the earlier Gallo powered sub on display in our store and no problem. Probably was plugged in from 2001 to 2004

Have always liked the sound of the Gallos ,since I heard the original Nucleus.Then the Nuc Ref (2 ball affair) and finally a modification by InSound which featured a 3 ball-woofers arrangement:9 ohm/90db.
The last ones I owned for about 5 years (InSound modded).Great sound and easy to drive with a minimum of 10 watts.
There is one thing to remember: these drivers are modified to fit the aluminum spheres ,the frames are,bent in fact.This requires the drivers be reconed after a five year period and finding the Dynaudio 17W75-4 drivers on the used market is nearly impossible.
As a side-note,I have been very happy with my KEF LS-50s also,but I use 2 pairs in parallel.It improves the scaling and allows the drivers to operate at lower distortion.

Nice post. Lots of good info. How do you set the 50's? With the cabinet shape one atop the other somehow whilst on their sides might be good.

... it will probably be good for 50-60 years, instead of the mere 30-40 you'll get by leaving things on.
Confession: I leave things on too. Still. Just not the Gallo subs.
I think it's pretty obvious that your Gallo sub is the exception to the rule. I'll bet that all other subs can be plugged in and left in standby indefinitely. Regardless, I would never own a sub I had to unplug and plug back in every time I sat down to listen. That's simply preposterous.
Good luck,

... that's the position of my (old school) tech, who is VERY firm about it applying across-the-board, other people's logic and experience notwithstanding. And frankly, not just applying to subwoofers. Obviously, not my feelings.
Dedicated power strips or line conditioners with on/off switches for all subwoofers is actually a good idea. The AC line filtering helps with those noisy subwoofer amps.
My subs have "Off", "Standby", and "On". No wonder yours melted.
Actually, my subs say "on," "auto" and "off." The "auto" position turns them on when a signal appears. Again, my tech says you can't count on "off" meaning OFF and the only sure fix is to pull the plug :-)
