I currently have a Klipsch RW-12d that I bought about 3 years ago used. My HT is a movie only environment. The only beef that I've had with the RW-12d is the port chuff with high volume and extremely low frequencies. Other than that, it's a great sub. I have an opportunity to purchase a used Definitive Technology Powerfield 1800 for about 3 bills. It appears to be all there cosmetically and the owner stated that there aren't any mechanical issues. I don't know much about this sub other than it has a 500 watt amp, an 18" driver, no auto on/off, and that it is an older sub. I'm assuming this would hit low frequencies nicely.
If you guys have any advice, I'd appreciate any input. Keep my Klipsch? Go with the DT? Any differences? I plan to audition it this week, but I thought I'd get some opinions.
