HSU or Dayton Titanic from Parts Express?

I have a HSU VTF2 and the Parts Express Titanic 10" and I have found the Titanic sub to be just as good as the HSU sub. The fact that it is cheaper and much more attractive (than the original grey/black VTF2 anyway), is a bonus. I now have two matching Titanic 10" subs in my secondary family room HT system.

I have not heard the Dayton sub,but on a related topic,I HAVE heard the Vifa two way from Parts Express.

Subwoofers and boxes are not my thing,but it seems to me that the Vifa two way and the Dayton sub kits would be a good value for money spent.

Thanks for taking the time to provide your input. I appreciate it.
