Rod,

So what's happening?

I just came on this thread.

Did anyone suggest that he measure his room to see if its the sub or the room that's causing his problems?

I have decided to build my own. I am in the finishing stages of my enclosure. Sealed design ~4.0 cu ft with 2 12" TC1000 drivers, using a velodyne Sc1250 (1250w RMS, 3000w peak) amp with a built in PEQ. It is taking longer than I thought it would, about a week left.

Hey RodH,
The SC1250 got tested over at AVS and it acquitted itself pretty well. It put out a solid 1000watts.

is that a surprise that is actually produces what it claims? Why does one channel produce 2X the power of the other?

i just want my sub's to sound like it does when I go to a concert, atleast at the arco arena the bass is litterally earth shattering, totaly and utterly amazing, now what...

I was just trying to be helpful.

no, no, no. I wasn't trying to be a jerk, it was a sincere question. I didn't know that a lot of these amps are overrated. I know you were trying to be helpful, and you were, and thats why I have jumped on that thread. I am sorry if you took it wrong. Thanks for the info.

It's all good man. I thought you were kind of shooting the messenger or something. To answer your question. Yes it is. It seems like most of the amps tested put out nowhere near what they are rated at under the admittedly harsh test proceddures..

the test on the left side is the 8ohm test, the one on the right is the 4ohm test which is why the one on the right is almost twice that of the left "channel"

though in reality, there are no channels it's a mono amp.
