My financial officer is just more lovely after she said YES to upgrade my sub I currently have a very small yammy 6 1/2 incher sub (45 watts preamp). The bass is just too weak to me and now I'm gonna call either SVS or HSU next Monday depend on what sub you guys recommended: 25-31 pci $499 20-39 pci $549 hsu vtf2 $450 So, please choose 1 out out those 3 for me!!! I have JBL n38ii as main speakers and I currently set as large, my small yammy surrounds as small and yammy center as small also, and "bass out" on sub only. What should I set after I get the new sub??? Thank you all and please lemme know before Sunday nite.
