I nearly posted this as yet another OT post in http://www.talkbass.com/forum/f15/fane-sovereign-10-125-sealed-driver-900277/, but thought it'd do for it's own thread. I REALLY like the form factor of vertical 2x12's (or the thought of a 3x12 ) and I've been checking out potential 12" speakers for sealed cabs. Everyone talks about the Emi DL2512 II and S2012, which do look very good in many respects and get a lot love for good reason. Faital doesn't really have a contender in this category, that I've found. Most other makers are after the high-performance market using ported designs. (I may have missed some though.) That Sovereign thread, however, got me thinking about the 12's in the Fane Sovereign line. These two jumped out to me: Sovereign 12-200*: http://www.mcmelectronics.com/product/FANE-INTERNATIONAL-SOVEREIGN-12-200-/55-2830 Sovereign 12-500LF: http://www.mcmelectronics.com/product/FANE-INTERNATIONAL-SOVEREIGN-12-500LF-/55-2845 Here's a comparison chart of the four. As you can see, I only looked at the Fane's that matched the "SVT alignment" (Qts = ~.94 with f3 @ 80Hz and ~1dB bump @ 150Hz,). There are others that work well in sealed, but they were scratched from my list because they go deeper / require a huge box / etc. and I'm assuming "sealed" draws in the trad SVT crowd and they're looking for that same tight but full bottom. Sealed 12" Speaker Comparison Best in spec got bolded. Really, not a bad one in the bunch, for any spec, at least on paper. There aren't many speakers that do sealed boxes these days, but it's good to know that there are a few out there that do it well. All are 8 ohm, btw. (Unfortunately, the 16 ohm Eminence Delta12-B's are too tight IMO. That would have made for a killer sealed 4 ohm 4x12. YMMV) The Eminence models are neo compared to the ferrite Fanes. For a 2x12, 22# for 2x500LF vs. 8# for 2xS2012. Percentage wise a ton, but it's still only an additional 14# in a nice compact package. At ~12 sf of panel area and ~1.5#/sf (my approx. for 1/2" BB ply) the box weight is ~18#. Add 5# for all the misc and a 2xS2012 would be around 30# and a 2x500LF would be 44# (about the weight of my 2x12 Portabass, incidentally). Composite would be about 5# less. All just made up ballpark estimates. Plus with enough power (i.e. with a 400-500W SS head), the 500LF's max low end SPL is equivalent to almost 4 S2012's or 2 of any of the others. I think that makes up for the weight. The lower sensitivity and higher power handling of the 500LF would make for a nice match with an SVT I'd guess. With a low powered tube head, any of the others would be better. I'm a little concerned about the S2012's excursion limited power being higher or equal to the thermal limit through most of it's range. No real warning before meltdown. I haven't heard that happening to anyone on here, so maybe I'm off base. All have EBP's that are toward the sealed side of the scale, but not far enough that they couldn't be used in ported cabs, too, if you get bored and want to swap the box. One could also use a larger box like 1.5 or 2 cf for a smoother low end and a bit deeper f3. Again, the smaller box was selected only because they happened to lay over the SVT. The freq charts look favorable for all. Nothing too funky in terms of dips and spikes, IMO. Getting up to that 4-5kHz+ range is big for me, too, so that removed a lot of the Eminence drivers from my list. YMMV. Again four are solid choices as far as I can tell from the numbers. The Fane's lack the track record here on TB, but might be worth checking out. Did I overlook any other contenders in this niche, TB? Any qualifiers to add to my hack analysis?
