What type of amplifier Bash or Sledge?
The PC Ultra 13 is certainly better with a slightly bigger woofer and the driver is a beast. I used to have a PC Ultra 13 BASH, great sub. Avoid the BASH amps.
The sledge are more reliable, newer and if you get the latest ones they have app support.
I also have the sealed box version of the PC13 that's a great hifi sub or small-medium room HT sub.
