I like that sundown sir //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ill keep my eye on it, how about the T3 TSNS 10??? i heard a little about it, looks promising.
Those TSNS 10's had spider failures within 2 weeks of using them. 4" coils on 10's just aren't a good idea. Puts way too much stress on the spiders.
Fi BL with some cooling upgrades, SSA XCON/ZCON, Sundown Z/NS as mentioned above (don't think many 10" NS were made though). There are some different subs such as an Fi Q that would work well but they won't like much more than around 1500 after cooling upgrades
