Day 9:
Test Day!

With everything dry and cured, the box was ready to mate with the subwoofer. Carried the box upstairs into the house, then carried up the driver itself, and then finally mounted it.


Dropped the sub inside the box and fooled around with it for a little bit. I'm getting a lot of hum- I don't know whether it's a cable or the amp. This is with my original Dayton 1000 watt plate amp. I've tried using a "real" subwoofer cable and then some regular RCAs to connect the amp to the Denon 2113CI AVR and the hum was present in both instances. I also tried using a different wall socket for amp power. I'm frustrated because the hum was driving me insane, and I gave up on any further troubleshooting. The good news are when the LFE effects kicked in it sounded pretty good and plenty loud smile.gif Shook the whole house down, got massive amounts of annoying rattling.

Until I get the hum fixed I can forget about finishing. Right now my plan is to coat everything in a 1:1 wood glue:water ratio, sand, prime, sand, paint black.(in simple terms).

Taking suggestions on how to proceed further. Thank you.

sounds like a ground loop hum.

sub looks good, are you going to paint it with normal paint or something like duratex?

Congrats and getting it together!

As for your hum - First, determine if it is a ground loop issue. Agreed, it can be super annoying. When you disconnect the RCA, does the hum go away? Do you have any cheater plugs handy to see if that will address the issue? If the answer is yes to these questions, you can then move on to isolating the source of the issue by disconnecting one component at a time. Start with the cable box and go from there. cool.gif

man, we just have one ground loop hum after another... Cheater plugs are just a good TEMPORARY fix, but they do help in isolating the problem...

Exactly. cool.gif Didn't mean to suggest it was permanent, but absolutely helpful along the way. I'd be lying if I said I didn't go months with a cheater plug 'fix' though, LOL. Tisk tisk, I know.

Looking good!! I don't believe changing outlets will make a difference if it is still on the same run to the breaker box. I have even heard of lights causing problems if they are on the same line to the box.(dimmer switches and halogen lights).

I don't actually ground the cheater plug with a screw like its instructions suggest? The purpose is to not have a ground?

The purpose is to add a ground to a 2 prong outlet. Using one to defeat ground protection is unwise, to say the least. The ground should be lifted on the signal cable, not the power cable. Doing the one can kill you, doing the other cannot.

Using a cheater plug took care of the hum for now. Tuned everything up with Audyssey a bit. Everything sounds much much better. Nice tight boom from the sub with respectable SPL for our room. Wife and I watched LOTR extended blurays 1+2 today at a decent volume level and they sounded AMAZING!!! Wife loves LOTR and was enjoying the rumbles, but probably not as much as I did! These movies have great LFE content.
