When using passive radiators, is it best to use the same driver design as the main powered sub? If a person chose a pr with a different makeup of cone and/or surround material or xmax rating, would it be inclined to have ill effects, by not reacting seamlessly with the main driver? I know about limited xmax will limit on how much power you can put to it. Is it possible to add more mass weight to compensate for lower excursion prs? I never used them,but am thinking of implementing them on a new build.

the maelstrom 18 is in a 6.5 cu ft sealed box with the recommended amount of poly fill. I tried with and without polyfill and left it in only took a portion of it out and had better results. I am using a QSC RMX2450 amp, and this thing does not even get close to max excursion. I estimate cone travel of10mm one way.
Yes the amp is briged at 4ohms with the gains all the way on channel1 . when I crank it up, the amp will start to clip before even getting near max excursion. Which I do not understand, with 2400watts pouring to this driver. Or do I need a bigger amp to get the most of this box/driver combo?
2000 watts will take the driver to Xmax at 20 hz so you definitely have a problem. On the back of the amp is a row of dip switches, is the 3rd and 8th switch from the top in the off position? (to the right)
out of curiosity, if I have my system volume up and the clip lights start to flash, I am getting full power from my amp and need to back off volume just a little until the clip light quits flashing right? If so by changing from the cleanbox to the sampson s-convert should cure what I am missing on the lower end. Has anyone checked the frequency response on the s-convert as well, like someone did with the art? Also my onkyo has a sub eq where @20hz and 40hz, I could boost 6db at 20, and compensate the rest from there going negative in the higher regions and setting my sub out signal hotter from+2 to say +6?
I'm assuming the problem is a receiver/amp voltage mismatch. But roll off or not, the Art Cleanbox should have taken care of that. Yet the result is your amp is clipping and you state the cone excursion is minimal. The HPF aren't turned on and you are running is bridged mode. I'm at a loss.
signal lights are green and present when any bass is introduced to the media played, the red lights are the clip signal indicators that warn you to back off. If clip limiter is on, is it ok to let the clip light flash occasionally without risking distortion problems?
That is my understanding of it. Hopefully someone will verify this.
