OK to place amp on top of subwoofer?


I would like to place my classe CA-100 amp on top of my large Velodyne HGS-18 sub to save space. Will the vibrations harm the amp? Also, will the amp pick up unwanted noise from the sub? Thanks!

No offense to Jeff or his answer, but if a non-mechanical component ( cd player, TT, etc.... ) can't deal with vibration, it is poorly built and under-designed. If you think about all of the "vibration" that any car audio component has to deal with, it will put things into perspective rather quickly. Then think about all of the powered subs that have their amps literally mounted inside and directly attached to the cabinet.

As to whether or not i would recommend it, probably not. One could look at the benefit of "mass loading" the sub cabinet with the weight of the amp. You would also have to take into account that this would change the sound of the sub due to altering the cabinet resonances.

Bottom line: try it and see how it works. Put something ( a sheet of MDF, etc... ) on top of the sub cabinet, try some type of DAMPING footer between it and the amp and go to town with some of your favorite tunes. If you have no bad side effects and it is more convenient for you, leave it alone and enjoy. Otherwise, it's easy enough to reverse with no long term side effects. Sean

Craig, i think that we are all basically saying the same things. None of us really likes the idea in theory but it may work out okay in reality. As i stated "would i recommend it, probably not". However, i don't know all of the variables in the situation ( i.e. available space, WAF, etc... ) and that's why i tried to cover both sides of the coin.

Either way, i've learned enough to know that we all see with different eyes, hear with different ears and think with different brains. Obviously, opinions and experiences will vary based on all of those things.

One thing is for sure though, i would NOT use cones between the amp and the platform that i placed on top of the sub if i did try this out. I can only see BAD things happening in that situation... Sean

I think that with the weight of an amp on them and vibration eminating directly below the bearings, the bearings would effectively couple the vibrations to the amp. I would think that using something that had a high absorption / damping factor would be more effective. Just a guess though with a lot of room for error. Sean
