Zenn,
I understand your point. I often cross mine below 50Hz with a steep slope. But in this system that I'll be building...I want it to sound dynamic. A high xover point helps augment where the midbass falls short. I like the Scan sub...my only problem with it is it's low sensitivity and it is output limited unless I run 2 of them. But 2 scans cost too much.
Tohsan,
As much as I'd like to try the Aliante...I couldn't get it from where I am.
Iswara,
Since you have the RS sub...can you confirm to me if the basket used is a cast basket? In the pictures it looks like a stamp steel basket. I'm much more inclined to purchase again the Seas sub since it looks like that it is built much better than the RS.
