Well to be honest I recieved a MAW-12 from Mark at Mach-5 and tested it in a sealed box. I found when you get upto the 400Wrms range with that driver you start to get some pretty evident cone noise. Having said that I have not tried it in a ported box either. We are going to drop it into a 4th order bandpass and try that as well. The driver is built very well and no doubt it will handle more power then its rating. Suspension is a little on the soft side so Im not sure if porting it will make an improvement or not. Best thing to do is try it. But keep in mindthat once it gets to the 400+rms power range its starts to reach its mechanical limits.
