I built a THT-LP powered by a Bash 500W plate amp and there are instructions for altering this amp's output characteristics by swapping out 2 resistors. Does this cabinet design benefit from making any changes offered by this amp?

The THT-Lp is essentially a 22hz horn. Because the horn design is a front loaded desig the driver is pretty well protected because it is in a sealed design. Protection from over excursion I am talking about.

So if I remember correctly the Bash amp is Hpassed at 17hz. So because of the horn design itself you wont get much output below 17hz anyways. SO I would not see the benefit in changing anything on the amp itself unless trying to use the amp for some other sealed subwoofer.

But maybe I am missing something?

I loved mine when I built it. I couldn't believe what 28watts could do. I thought I was going to damage the driver because my walls were rattling so much. But after seeing that it was only 30 watts being used I was amazed.
