Well this afternoon i had to go by the home audio store in town for a cable ground isolator and had a listen to the Paradigm seismic 12.The thing really did a great job,I was very impressed!Their price was around $1600 which is more than 3 LFM-1's.The information from the link apodaca supplied shows that 1 LFM-1 averaged the same output as the seismic 12 which i find hard to believe after hearing the Paradigm.The LFM-1 must be a super deal for a sub.Think 2 LFM-1's will be in my future.
