Ken if you're at all curious about the world of DIY (do-it-yourself) this is a perfect way to get your feet wet. Since all the hard stuff has already been taken care off all that's required to build this kit is about 30 minutes to assemble it and a little paint to finish it up. Its extremely easy to do and you've got access to a lot of support online so i'd say go for it! As far as performace goes this should easily best anything else in this price range and once you've got your first DIY project completed you'll never look at speakers the same way again I must warn you though the DIY hobby is addictive and you'll likely find yourself building something else shortly
Andrew, can the EZsub14 be used on a A/V receiver without a Subwoofer output? The reason is that I also have an old JVC A/V receiver that does not have a subwoofer output but I wanted to hook a sub on that one as well.
Yes the plate amp has both line level and speaker level inputs so you could simply run the main speaker wires to the sub then run another set from the sub to the mains and let the plate amp filter out the low bass from the mains. This is actually how I have my EZSub set up in my living room.
