Hello everyone. The "failures" that Jack brings up on the S-12 weren't related to the power consumption. That thread (2323) had 4 or 5 comments about amps and we've already taken care  of each customer by sending them replacements. Please keep in mind that we sell thousands of these wonderful subs, and as with any electronic product, there are going to be a small percentage that require repair or replacement. 

The 22 watt power consumption is something we are looking into. I've forwarded this information to our engineers so they can look into it more thoroughly. If there's a problem, we'll take care of you, you can count on that. We are all very conscientious of our environment, and as we grow we will continue to minimize energy consumption through all our products.

Glad to hear that you're working on a solution to this problem!  Will the next batch of subs to be shipped out (5/18) be delayed to have a fix applied, or will it be handled on a case by case basis?  Is there a way to determine at home if the sub is drawing power in stand-by mode?  Thanks!

 

Peter 

Hi Peter. We haven't confirmed that it is a problem at this point so we will be shipping backorders on time, and quite possibly earlier! We're hoping the container arrives late this week. If anyone has been holding off to order product due to the backorder, I would recommend ordering sooner than later as many customer are already in line to receive something off this shipment. If you've been thinking about ordering, consider placing your order now so we can reserve your product for you.

Good news then!  I've got a 5 series on hold, waiting for the sub and the 533 VAC in black. Are the centers coming in also?

Yes Peter,

There is a way to see if the amp is drawing power when in standby.

If the heat sink remains, lets say 10 degrees above room temp after say 9 hrs in standby; the amp is drawing power. Both Owen and I found this to be true with our S-10’s.

I would like to be in line to try one of the S-10 amps coming in and hopefully put an end to this issue.

Jack

Ben,
So how do I get in line to get one of the new shipment? I'm on my second S-10 already and would really like to resolve this once and for all. Thanks.

Owen

Peter,

 

You must be somewhat concerned since you hope the issue will be resolved before you receive your S-10

 

Jack

 

Yes, of course I want the sub to operate in the fashion it is intended to. I also don't want to waste any electricity.  I trust the folks at Aperion are working on a solution and if my sub does indeed suffer from this power problem it will be fixed.  Again, this doesn't seem to be an issue where the sub isn't functional, I can live with that, for now.  I'm just looking forward to my new speakers!

Hey Peter,

 

I didn’t mean to dampen your spirits in any way regarding the arrival of your new babies.

 

I am sure that you will be quite satisfied if not jubilant once hearing and seeing the Aperions.

 

I just want to help Aperion make their products the best value out there.

 

Jack

To all :

 

I believe that Ben is trying to resolve the S-10 issue, but it is one that may not be easy to resolve. I have spoken with Ben on the phone and have exchanged E-mails.

 

I have never been disappointed after conversing with Ben.

 

My experience is one that gives me the desire to find answers to problems.

 

If you contract an Engineer to find a product that suits your needs and that Engineer finds an OEM supplier that can meet required specs, then you need to go through the resulting chain of command to resolve related issues.

 

There may be a big difference in the customer service that Aperion provides and that of Aperion’s OEM suppliers.

 

Jack

OK, I have spent more time with this than I have repairing machines costing 100 times more than the S-10.

 

I do not believe that the speaker cone is active when in OFF. I placed a .001-inch machinist’s dial indicator against the center of the cone with the S-10 plugged in while in the off pos and then unplugged and found no movement of the cone.

 

This brings me to where I think the problem may lie.

 

Owen in post # 4423 mentioned a humming noise coming from or near the heat sink. I used a long shaft, 14” screwdriver to act as a stethoscope and the 60HZ hum was definitely noticeable.

 

I believe that hum is noticeable because the amps transformer is always online and drawing power. The transformer may have poor efficiency possibly leaky filter capacitors after the FWB fed by the transformers secondary.

 

My SPL meter was able to detect an increase of 3db when placed close to the heat sink with nothing else on in my home.

I am hoping that someone from Aperion will respond to the questions raised in this thread that have not been answered.

 

I realize that they may need to settle in after the HE show in NY, but a response would be appreciated.

 

Jack

Hey Jack, I also noticed a hum coming from my S10 when everything was turned off. Doesn't matter if the switch is in auto or off. Only way to stop the hum is to unplug the power cord.

That is what I am doing now whenever I am not using it as I don't want to waste electricity. Hope there is an easy fix for this.

Hi Gary,

 

Owen noticed the humming sound actually before I did, but I was confirming the 22 watt draw and the temp rise of 10 degrees above room temp when in OFF.

 

Ben E-mailed me on 05-17-07 that his engineer in China was working on the issue then.

 

Well let’s see, it took me 2hrs to conduct my first current test, which showed a 22-watt draw, but I had to make a power patch cable. I have worked in the field of Electronics in a variety of capacities and know that even an entry level Electronic Tech should be able to conduct the same test.

 

I started this post one month ago and that was after Caleb’s post # 4350 showing interest in my findings when I responded to Williams “Sub Amp Question” in the speaker forum.

 

I would bet that you would see the amps heat sink about 10 degrees F above room temp in the OFF position. The “fresh supply of amps” has been delayed until 06-08-07 but I doubt there will be a fix applied.

 

I also unplug the S-10 when not in use. The bright side is that when I turn a lamp off, the lamp is no longer bright and becomes cool to the touch.

 

Jack

Hey Jack, now my next question is do u think I should keep the S-10 and wait for a fix or should I send it back b4 the 30 days are up? I know ultimately that is something I have to decide myself but just wondering what u thought.
