For fun I just went back through my old IB build thread and found the following which summarized my initial experience with the SMS-1. This was from 2007:
I use a SMS1 with the latest software to prevent distortion issues and roll off. The curve was pretty flat un eq'd but I had dips at 60ish hertz and a big peak around 25-35 hz. They have since been removed with the SMS1.
Since i've eq'd I'm even more ecstatic!!! Viny Paul (panteras drummer) is now in my living room! Chevelle's bass guitartist brings me beer from the refrigirator while he plays in front of my projection screen and jams away to Still Running! UNDERSTAND THIS IS THE KIND OF PERFORMANCE I'VE BEEN SEARCHING FOR EVERY SINCE I'VE BEEN INTO THE HOME STEREO GAME FOR MY HOME!!!
Anyone who says IBs don't have slam needs more power and or EQing trust me. This thing just embarasses my previous setup which I was totally happy with for the most part!
Since EQing the infrasonics have become more apparent on movies as well. I'm sure this is because I flattened out the 25-35hz peak which made the other lower frequencies become more aparent.
If you guys like I could try to snap a picture of my EQ curve presented by the SMS1 on the projector. Just let me know.
29 Litres of Infinite Baffle Bliss. Oh, and the rest of the setup isn't too shabby either!
