Looking to replace my Klipsch KWS-12. My current HT is 60% movies, 30% gaming and 10% music. I have approximately 3500 cubic ft to fill as my HT room is 21.5'w10.6'h15'd. I have narrowed it down to a few based on thier size as I need to put at least one in a cabinet underneath my screen. I'm looking to purchase 2 and then on down the road another 2. My choices so far are 1.eD A5s-300 2.Sunfire HRS-12 3.Rythmik F12 or 4. The new SVS SB-12NSD when it is released. As you can see I need a 12" due to the limited space in my custom cabinet. My plan is to put two in the front listening position and then when I have some more $, two behind the listening position. What do you guys think? Also, will I see an noticible increase in performance and that low bass upgrading from my KWS-12 to one of these? Thoughts or suggestions are appreciated.
