    I have had this particular driver for a long time and I love it. It's very similar to the stryke power 15 except it has a paper cone and dual 2ohm coils. I bought it directly from tc sounds. I recently built a new box:
    2 1400 gram pr's, 145 liters, full power from mackie 1400i. So here's the deal, I can't get this thing to really rock. WHen the mackie clips it's moving about half its xmax. I have had this sub moving a solid 2 inches before, so there is no question whether or not it can do it. But I can't believe the 1200 or so watts isnt enough! (By the way it was moving 2" in a 100l box with one pr 'slapping away' and my 1000 watt car amp at 20hz and under, below 10 hz it will do over 3 inches!) I had mackie test the amp and they say its fine, but I still feel its weak, even though it passes. It might be my living room too, it has a very high slanted ceiling. I havent painted the box because Im not satisfied yet. Can you guys think of anything? I'll post pics in a little bit.

    Thanks

    Sounds to me that the tuning of your system is on the low side, that is the PR,s are on the heavy side.

    - Have you measured the output of your system?

    - Are you sure the amp is driven within its specs?

    - If you are loading it with 2 Ohms/ch most overloadmargins are probably used up if you ask me.

    I cant measure the output, no meter. The amp is 2ohm stable in stereo and 4 ohms brigded. I am starting to think it is low tuning Im comsidering buying different ones or attempting to lighten these up. I just need a good method to insure that they are balanced and even.

    what the wireing on the driver are you going for a 1 ohm bridged or are you using the 2 ohm stereo mode on the amp?
