fEARful Cabs

#10
My Fearless 210 is a 4-ohm cab. The newer Fearless line (only available from Authorized Builders) has tighter lows than the fEarful line. It weighs 46 pounds and gets as loud as a good 410. My review, pics, sound sample here -> fEARLESS F210

P.S. the 8-ohm "restriction" is based on the driver characteristics. It is what it is.

Wouldn't that cut my watts in half?

Yes, but halving the wattage only decreases volume by about 3db.

More to the point, all 12" 4 ohm cabs are not the same. Some have higher sensitivity than others, meaning they're more efficient at turning watts into sound. Also, different frequency response means that some cabs may require a lot of EQ to get the sound you like, which may reduce how much effective power you can get from your amp.

So don't write off the Fearfuls because of their impedance. Try to find someone near you who has one you can try.

1. the 8 ohm eminence 3012LF is a better driver than the 4 ohm (so I've read)

::::BASSIST::::, I'm curious. I'd like to read that claim, if you remember where you saw it; or if not, could you paraphrase?

I use a custom 4-ohm variant of the Eminence Kappalite 3012LF in the 4-ohm version of my Thunderchild 112 cab, and I use the stock 8-ohm 3012LF in the 8-ohm version of my Thunderchild 112 cab. (Other manufacturers who use a custom 4-ohm variant are most likely using a different one, tailored to their needs.)

The response curves are similar though not identical, power handling and excursion are identical, and my particular 4-ohm version is a little bit more efficient than the stock woofer (in addition to its higher voltage sensitivity from being a 4 ohm load). The other side of that efficiency difference is, the stock 8 ohm woofer goes a little bit deeper in a given box size. That's the tradeoff.

Whether one is "better" than the other depends on what your priorities are, and if either is indeed better, it's only by a small margin. The main difference is, 4 ohms vs 8 ohms.

I am able to get a slightly more "studio monitor like" response from my 8-ohm Thunderchild 112 cab, but that's mainly because its lower voltage sensitivity allows me a bit more leeway in choosing compression drivers, and therefore I can get away with using a different compression driver that has a nice polymer diaphragm.

Can't remember a specific thread where I read that, but I am pretty sure I saw it on the greenboy forum.

Could more applicable to the 3015LF perhaps?

Thanks for replying.

The greenboy forum being a fairly large place, I'll have to put off searching until another day.

I also used a custom 4-ohm variant of the 3015LF in the original version of the Thunderchild 115. In this case, my variant was quite a bit more efficient than the stock 8-ohm version, trading off a fair amount of low-end extension to get that efficiency. I would readily concede that the stock 3015LF is "better" for a fEARful, but would claim that my woofer was "better" for what I was trying to do. In other words, I think that which is "better" probably depends on the application, as any woofer with that mighty Kappalite motor is going to be quite capable.
