Last week I ordered some Blueprint 1203's, since ThomasW and Jack Gilvey seem to be doing a fine job covering the "large" speaker end of the sub world. These babies are probably some of the most unusual 12" sub drivers available.
I had been toying with the idea of a Linkwitz transform box for these (sealed, EQ to get low end, taking advanatage of their enormouse Xmax - about 28 mm). But once I sat down and ran the numbers, a different story emerges.
Bottom line, I'll be doing a true SW-12 Klone, or rather, I'll be cloning a 12" version of our Aerial Stryke AS-15. With the same maximum input, there's over a ten dB difference in maximum output in the low bass, and that's just too much for me to ignore.
But still, the idea was cute, even 102 dB from a 48L sealed box is pretty impressive. But 112 dB from 80L is even more impressive, I think.
