posted_imageOk, I am working on getting a new box built for 3 thunder8000's running off of one 81001. I have a box set up, and everything looks ok except for one thing... my max acoustic power graph seems like it may show a problem, but im not 100% sure how to read it. I attached a general picture of the graph. Do i have a problem, or is everything alright?

Thanks again guys!!!

That's fine. What that graph is telling you is that at thermal maximum, (the flat line) your woofer, in that given enclosure will do 127dB at 27Hz. Below 27Hz, your system will be unloaded mechanically, your woofer will flap with very little input power, and right there is where I would apply your subsonic filter.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
