Wow, I don't pay much attention to AVS or any forum for a few days, and come back to a blind test and 365 posts! Glad to see a thread not go overboard and start to get out of line here!
I could swear I mentioned somewhere how difficult it was to have to be the "blind" person in a test and how difficult it was to tell subs apart.
I just wish Arch could have been one of the blind guys as I recall your comments about loving ported vs sealed.
This thread really points to why subs like the Submersive, once again, is as good as it is and as expensive as it is. It's one thing to throw a driver into a box based on a WinISD model, apply some inexpensive amp, and hope it's going to peform. It's a completely different thing to design a sub from the ground up, including box, driver, amp, protection circuitry, proper signal shaping, etc. and test it extensively before bringing it to market. It saves all the guess-work required for the end-user when it comes to outboard amplifiers, EQ, clipping issues, gain structure, etc.
... and guess what? It costs more.
Awesome work guys.
