Thanks to everyone here I've decided to save $1,000 and build my 1st sub. Now I've changed the specs a bit of what I want. 1st it was a very small cube. Now I don't care if I can make it tall w/ a small footprint - ie sonotube? and place it near (2-3') the TV. So what's the best sub I can build, money almost no object (I was going to spend $1400 on a Velodyne), tools and woodworking skills no object either. I've read so many links and articles I can't tell if it's better to build a sealed enclosure bass cube w/ a 12" Shiva or 12" Titanic or a ported box or a tube or ??? What do I want to achieve you might ask? Low bass ~20hz Ability to play loud Very musical - No mushy or boomy sounds 60% HT, 40% music Can handle the THX LFE output of my B&K receiver. So what drivers? What amp? PE 250w or Adire Audio HS500 or? Enclosure? Tube or cube or? It does have to be wife friendly so nothing enourmous or hideous. If you all agree a tube is best, is it ok to wrap w/ an oak veneer to match my Klipsch fronts? I just printed out the Shiva 142.5L RP Shiva EBS pdf. This looks like what I'm looking for. I will do a search on the EBS here but is there something better to build? Thanks to all who help.
