On the contrary, I think it is fair to compare them, and I think this one holds it own pretty well. It isn't a whole lot more expensive, and it does look nicer, and its output matches the LFM at certain points while surpassing the PB12 at others. It just doesn't dig quite as deep, but you are only missing 5 hertz against the PB12 and LFM (in two ports mode), if you ask me that isn't bad at all, especially when you consider the size of the sub. I think Aperion made a good decision between where to tune this and how big to make it, and it's a sensible compromise.
