Don't bother getting a sub that is a grand if you don't know what it is capable of.
the only box that would POSSIBLY produce your desired output (15-75) would be a bandpass box even then it would fall quite short and sound like ass doing it.
Your sub does NOT reproduce those frequencies smoothly I promise you this.
If you want to do this kind of stuff KNOW IT, and know what the terms mean, and how things are accomplished.
I can tell you this much. I've personally heard one of those TC LMS Ultra 18's. I KNOW what that subwoofer is capable of (in a car environment). And that thing is an absolute MONSTER!!! If I could fit that beast in my little Prelude, and had a spare $900 to blow on a driver, plus another $1000 or so to blow on amplifiers to push it....I'd buy one
The setup I heard, he was tuned to 25Hz, 9 cuft, slot ported, in I want to say it was a Jeep Cherokee. He had a good 5000w RMS pushing it (all Sundown Audio amplifiers, 4x SAZ1500's strapped). And my GOD did that thing hit every note down to 20Hz, from 50Hz. He had his subsonic at 25Hz, and his crossover at 40Hz.
Now granted, that's all he could hit. The rest of his speakers weren't up to the challenge.
But even with what Corey has in mind, he's NEVER going to be using the full potential of that subwoofer with a wimpy 1000w RMS. Nor is he EVER going to be happy if he's looking for 2-3 octaves worth of output cleanly from a subwoofer.
