Looks good!

In regards to how high up to run the subs, it is recommended to be below 120hz, or lower, since above that region one will be able to locate where the sub is. In your instance, you could run your tops down to 80-85hz, and have the subs run up somewhere near that point. Where that point is will be up...

I used my phone and video-recorded the insides wherever I could to see how things looked and if anything needed attention. At the end of the "research", I committed to the PU adhesive on the final side since I couldn't find any other source.

I won't be able to make it. Enjoy your day!

Understood. Thumbs up.

Hi Matt. Welcome to the forum!
Unfortunately, I do not know the answer for you.
I was wondering why you are yelling (all caps).

Cool!
Dare I say "It looks like a Simplexx"?

Awesome. A single t39 takes about 40volts (atleast with the KappaLITE 3012LF)?

My plans say that the 3012LF should be limited to 55v. (mine is a BP102 with a 35v limit).

Thanks.

Luckily these sockets have insulating washers

It could be a ground problem. When there's more than one path to ground on the inputs a ground loop can cause noise. Since the amps appear to be chassis grounded via the power supply the input wires should not be grounded at both ends of the input wires. Bill, are you saying that the input negative...

I took a DR250 and a T39 to a house party last night. It's amazing how little power they need. 60x60ft room with cathedral ceiling. 85ish dB at 20ft away, and the T39 was only getting up to 4volts. We tried to keep it reasonable so that people could have conversations. When the guests had left, a f...
