For what it's worth, I'm going from 600 RMS/RE SE 15 to 1,100 RMS/Two Type R 12s.
I ordered the subs last week, they will be shipped out tomorrow, I'll have them later this week.
Despite the fact I only have the Type R's rated RMS power to give them, I was thinking on making the box a little bigger than called for by Alpine to compensate.
My SE is pretty darn loud, I mean it sounds good for the 2.2cf sealed box I've got it in. But hell, if a single Type R 12 can eat up all of that power and still beat an SX (step up from what I've already got... SE), then I'm jumping on that. Hence the reason I bought a pair. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
I haven't heard the newer Type S's, so I can't comment on whether or not they'd be comparable to the SE's or not. I would ASSUME... Keyword: ASSUME... that the RE SE's would have the upper hand on the Type S's, however, as some tests have shown here, the Type R has the upper hand over not only the SE, but the SX.
We'll have to see what happens later this week. I'm rather excited... getting the wood for the box tomorrow. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
