Hi , I have a Klipsch R12SW and am interested to add a 2nd Subw. Today I read an article on Audioholics , disclaiming myths and they stated that in a linear field all subs sound alike Now I know that the R112SW has more power and can go lower. Would it be sensible to pair it with R112SW ? Maybe Audessey will fix any differences ? I always regretted, not going a bit more powerful with my sub. So if this would work just fine , I will go for it , otherwise I'll get another R12SW or the newer 120 model... Rest of my setup: Marantz SR6010 , speakers all Klipsch: RP-6000F , 4x RP-140SA, RP600M & RP-450C Thanks in advance for any help / advice !
