I would not put any electronics on top of the subwoofer. Same way I wouldn't want a amp inside any subwoofer.

Martin Logan along with many others have been doing it for years with superb sonic success !

I just did a quick Google search on "MartinLogan Subwoofer Amp failure" and found:

So I guess it's "successful" until your MartinLogan subwoofer's (or any brand) amp fails after the warranty is over. Then it becomes "unsuccessful".

Do a Google search and I bet you will find many examples of Subwoofer amp failure. A friend of mine has already replaced TWO amps for his big SVS subwoofer.

My theater setup has amps on top of the subwoofers. Unless it's a light amp and the sub crawls insanely, should be good, just have to try it.

poop happens, I've owned several Logan 'hybrids' (built in amps to drive the bass speakers) and have never had an issue. My Velodyne sub (DD-15) has been flawless for over 10 years

I do think that amp ON TOP of the subwoofer is better than amp inside the subwoofer.

Depends how inert the sub cabinet is to an extent. I've used a dual opposed sub for a tv stand for years without issue.

How about the sub cabinet? Does it "crawl" or do the feet you have keep it in place? Still may not be the best place, but may not do too much harm. No other way to place things?

 

[Kingnoob]

Sub is stable on a diy riser . It won’t be moving anywhere. The tower that sits ontop has never fell off or moved .
I know the receiver is too heavy to just fall off, I’m asking if the vibrations from sitting up there will hurt the amplifier? Or no
I mean subs have plate amps that vibrate always .

Hah! There might be less vibration on top of the cabinet than a few feet away!

You might be able to get away with the amp on the subwoofer as long as you have amp on something to dampen vibrations (like thick rubber feet)

The onkyo has those but I can try and use multiple levels or layers of carpet to desperate the sub from the amplifier.
Running out space in bedroom this is to save space . If it’s dangerous to the amplifier then forget it I need to find somewhere else to place it .

Putting multiple layers of carpet would be a good idea, but make sure the amp has space under it for cooling

You ever set a amplifier for surround ontop a sub ?
Wouldn’t carpet be good And few layers for it? I have a little pc riser stand used for monitors I can set it on .

No I have not but I have seen other people set an amp on top of a ultimax 15. But the idea of the PC riser stand is a good idea. It might be better or equal to carpet.

 

[Pogre]

Setting electronics on carpet doesn't sound like a good idea...

WOUDO WOULD you need carpeting between the pc riser ,? And the sub
