If the STF-1 and LFM 2 are essentially the same subwoofer and should sound very similar, I have noticed that there is still a price difference. The STF-1 sells for $249.00 for a single item, I was planning on purchasing 2 for a total cost of $498.00. I have also noticed that for $549.00 Outlaw sells two as well. It is only $50, but this might suggest that Outlaw is abandoning one of the main principles in its' marketing strategy. Is there a real difference in the subwoofers? If they are the same, has Outlaw just overlooked this price difference?
