Been thinking about adding a little bit of bass to the home cinema system, both for watching movies (i.e. LFE) and to support the bookshelf sized front speakers. Was hoping to not spend too much money, but I also don’t want something that sounds bad, or only provides rumble without much distinction to different sounds. Got a medium sized room which I’ve estimated to 67m³ (2350 cubic feet) so I’m leaning towards dual subs.

Current options I’m considering:

  • Pre-built subs, probably XTZ 12.17 Edge
  • DIY Dayton Audio 15" flat pack, with either RSS310HF-4 or HO-4
  • DIY VBSS with GRS 18PT-8 18"

The total cost for either option would be around €1500, since I would need to buy some power tools to build the VBSS.

From what I’ve read the VBSS is supposed to sound fairly good, especially in the mid-bass region, while lacking some very low bass compared to the DA Reference and Ultimax drivers.

Anyone have some experience with the above subs, primarily the VBSS?
