Did some more listening tonight at my best friend's home in San Antonio. New neighborhood so he does not have any neighbors at this time. Started the night off with more music with such songs as Dion Warwick Walk on by, El Debarge Lay With You, Denise Williams Silly, and Kenny G/Chante Moore One Moore Time. The SI 24 easily blends in with my mains while adding deep, precise bass.
Bass is tantalizing smooth. Adds so much depth and controlled thunder to my setup while at the same time not drawing attention to itself by overwhelming the mids and highs.
For the movie lovers I watched Pacific Rim. Connected the driver to one channel of my friend's Ipr2-7500 for added fun tonight. We were tickling the spl meter at 127 db. My ears were ringing and my stomach felt like I was going to go number 2 on myself. Bass was all enveloping, room crushing, and just plain awesome. Ultra deep rumbling, vicious low end grunt when called for, aggresive and thunderous strikes which dissapear as quickly as they hit with no sound decay or lingering. This sub definitely sounds like its digging deeper and nastier down the audio spectrum with movies than my Ftw 21s did with tighter more precise bass.
The FTW 21s bass sounded like a heavy meat cleaver when they would really hit which I love for movies but it just would not blend well for music. The SI 24's bass is like a hammer. Heavy and precise. I always said I would never, ever pay LMS 5400 money($800 and up) for one driver unless it was capable of high spl, reasonably low distortion, and precise articulation. The SI 24 is a homerun with all of the aforementioned criteria in my opinion.
