Right now I have: Front R/L: (2) JBL Northridge E80 Center: (1) JBL Northridge EC25 Surround L/R: (2) JBL Northridge E30 Surround Back L/R: (2) JBL Northridge E20 Subwoofer: (1) JBL Northridge E150 Before my 30 days are up--and because the price difference is very minimal--I'm seriously thinking of upgrading to: Front R/L: (2) JBL Northridge E90 Center: (1) JBL Northridge EC35 Subwoofer: (1) JBL Northridge E250 Just wondering from the gallery here what the thought process here is. I definitely am going to upgrade the center speaker because I've read here that there is no comparison between the EC25 and the EC35 because of the 3-way including a mid-range in the 35 over the 2-way "woofer"/tweeter in the 25. What I'm on the fence about is that I love the E80s but would like to upgrade from the 6" woofer to the 8" woofers in the E90s for better lower frequency handling and a little more ooomph! in the bottom end. Also, I am swayed a bit more by the fact that the E90s are a bit wider by over an inch and weigh a little more because it would make it that much more difficult for one of our cats to tip one of these towers over! And perhaps upgrade the 10" subwoofer in the E150 for the 12" one in the E250 for a deeper rumble, however, the 150 is clean in my living room right now and I notice the Hz difference in only 2Hz between the two, so I'm thinking the E250 would just be too boomy and muddy up my current room. And then maybe perhaps the E90s would just be more boom to muddy everything up more too. Or perhaps I should stay with what I've got. It all sounds beatiful and smooth, I just wish there was a little more smooth bottom end with a little more ooomph! without too much boom. Heh, I guess that's what we're all looking for, eh? I'm also probably going to stick with this Northridge series because the Black Ash finished wood cabinets are beatiful, and let's face it, the wife loves them as "funiture" so we're sticking with this series. Anyway... good stereoscopic surround sound is fun.
