Wow! Three months later and I finally got it together yesterday! I waited three weeks for my Shiva to arrive all the way from the deeeep south.(at least from here in Alberta it is!) Thanks to Brian Bunge for selling me the only Shiva left in North America! I used a 150w plate amp from Solen.ca,although ThomasW said that I might want more later, he is probably correct but the wallet talked! If I upgrade later it will be off with the Shiva and onto the next size. Along with a new plate amp! I have a slight problem though, the WAF was low...she said that it is too big! I kept it hidden until it was all together, then I surprised her when I brought it up from the basement! Well now onto how it works. I slapped my Eagles"When hell freezes over" dvd in and cranked it up (a bit at a time)and WOW! I have my ht set up in the family room which resides on a cement floor, well this sub rumbles the cement floor when I stand about 2 ft back! Today I watched T3, it rumbled everything around, I even set it out into the floor so it didn't corner load! As stated before, it is a 54l sealed front firing "Athena" look a like. To make it a better WAF sub,could anyone suggest a smaller size that will still be good?
