I know quite well how low frequencies sound... The frequencies you guys talk about are the ones Michael Bay loves to put on his movies and some home systems won't reproduce.
Reading the other posts I see the fEARfuls being compared with the ACMEs. Is that so?
I've played through ACMEs many, many times... Not bashing the brand, nice cabs for great price. But nothing really special... Quiet and power hungry little things. Not sure if I'll be understood here, but not enough grace and excitement on ACMEs.
FYI, way back when, a couple of the TBers who used Acme speakers were into the concept of a full range, full sounding bass speaker that 'fixed' some of the things they (and others, including me) didn't like about the Acme's:
1) So much low end extension that the trade-off in efficiency to get what amounted to sub bass was not particularly a useful trade-off in live performance
2) The small mid driver in the Acme tended to become buried by the big wump of the low end driver
3) The physical characteristics of the OEM Acme 10" drivers resulted in the strange combination of needing a LOT of power to get the things pumping, but pushed the limit of thermal safety and XLIM.
So, these two TBers (AlexClaber and Greenboy) started down the path of taking what was good about the Acme (full range performance with impressive low end and no low mid hump, nice dispersion of the upper mids, relatively small size), and 'fixing' 1-3 above (and, for the Acme fans, many believe these fixes were not needed).
Those two guys ended up being 'Barefaced Cabs' in the UK, and fEARful over here. Using the PA quality 3015(12)LF drivers, various heavy duty 6.5" mid drivers, decent crossovers, and a relatively large box made out of lightweight materials, I think they were successful.
What you get is more absolute low end extension than the typical production cab, but not so much to be a problem regarding efficiency (I believe most of the designs are -3db a touch above 40hz). You also get a mid driver that can keep up with the low end so you don't lose your definition on stage, and you also get INCREDIBLE XMAX and XLIM specs that result in a very open, even low end, even when slapping and digging in.
As has been posted, all these cabs have a voice, and the extended low end and bright upper mids are not necessarily the 'end all' in tone. However, the specs are accurate, and the performance is pretty impressive.
When you hear a Mesa M9 (for example), with literally no hi passing, wumping into a 15/6, whether you dig it or not, it is impressive as heck, especially if you have a nice traditional 410 or 212 around to A/B. You still might like the 212 (I prefer my Bergantino AE212 over virtually any other cab), but the 15/6 (much less the 1212/6) will 'outperform' it in a technical sense.
Again, just trying to clarify that even some of us (like me) that don't really appreciate the extra low end and the nature of the upper midrange in the fEARful, for the most part appreciate that the design goals of both Alex and Greenboy were achieved pretty nicely in each of their product lines.
IMO and a lot of IME
