Axiom owner here. I've been thinking of upgrading my sub but I'm having a hard time figuring out what to get. I currently have an HSU STF3, http://www.hsuresearch.com/products/stf-3.html.
While overall I'm generally happy with the sub, I do feel like I could get something that digs a little deeper. Problem is being in Canada it seems my choices are a bit limited. I could spend the $1,200 on the EP500 but with taxes that comes to $1,400. I thought about the SVS SB13 Ultra but that is already at $1,400 without taxes. I've also been looking at the HSU VTF3 MK4 which is $650 but will probably cost another $300 at least in taxes, duties and shipping.
So I feel kinda of stuck. To be honest I'm not partiicularly found of the look of the ep500 either. The rectangular port and chopped sides of the driver...I find it looks well ugly...this is going in my condo and has to fit in with the decor....
