although i never got to use it with the tc sub. i did installed a 12" type r from one of the projects i have going, all i can say its wow. i didn't think the type r could hit soo low so good. i like it. it was low and loud. it response was pretty much from 30Hz to 90Hz this is playing tones and using my ears to tell for how clean it sounded.
here are the final pics of the enclosure.
the neighbor heard it pounding in the trunk of my car from his living room. lol he came out to see what the hell it was. since he has two 15" in his suv, he couldnt belive that it was a single 12", haha, he offered me $120 for it, but the wife didn't agree on the purchase. so im stuck with it.
so i think i might put it up for sale on this forum. or get another 12" type r and put it in my wifes minivan, haha. not!
i don't think making to whole bigger to fit the 15" will do the sub justice.
so i have other plans for the TC-3000 15" sub. something like taking the seats out of the back and making some sort of fiberglass install back there.
who knows.
ill probably make a thread about it later.
