I did all I could to get my DIY center channel as close as possible to the top of my 32" TV. Well maybe to close. I am having a small issue with one thing I did not take into consideration. My crossover is so close to the top of my TV, it is picking up and amplifying a slight electrical hum from the CRT. The cross over is within 1" of the top back of the TV. This happens when the center channel is totally disconnected from my amp with the TV being the only thing turned on. The bad news is, the crossover is liquid nailed to the bottom of my enclosure and is not able to be moved. I wish I would have though about this and liquid nailed it to the top of the enclosure giving me 7 1/2" of air insulation.

Anyway, what can I use to experiment with in between the center channel bottom and TV top to help shield this slight electrical hum from the CRT getting to the crossover?

Anyone have any suggestions?


Thanks!

I guess it's silly to ask if you can turn the speaker cabinet over.
Usually this would not be a silly question. But this is my center channel:



It is physically built onto the shelf because I needed the extra .75" saved by doing it this way. Also it has a 10 degree slope added to the front to direct the sound toward the seated listener.
