If you were gonna build a fEARFUL

Neither. That head is going to hang over the sides of either of those cabinets.

Both cabinets will MORE than handle the power, and in fact will be loafing, but you may want to put the lighter component on top (and that's likely to be the cabinet).

Is that head really 80 pounds?
 
Well, it's up to you. Fearfuls are designed to sound the same regardless of which speaker configuration you choose, so they really only differ in terms of total volume and power handling. If you're looking at two-woofer cab you're going to get a 4 ohm cab either way.

For me, one of the perks of going Fearful is that you get a lot more sound per pound, especially when you go with one of the builders using composite instead of plywood. I was using an Aggie GS212 at 70lbs. Now I'm using an AoN 12/6/1 at 30lbs that is louder at less than half the weight. It's plenty loud for me (and I play medium sized rock clubs unmic'ed).

For me a giant Fearful cab sort of defeats the purpose of switching in the first place - small and light with big sound. If anything, I could see adding a 12sub to my current config, as a potentially huge rig that can still fit in the backseat of my Honda.

The normal options for this head (which is about 26" wide and about 80 lbs) are a 150 lb 8x10 (50" tall) or a 107 lb 4x12. Something like eight 6550s, as I recall. That's a 180-230 lb rig.

He automatically gets smaller and lighter with any of the fEARfuls <G>
 
a VBA 400 is about 26.5" wide (26.33") so there aren't many cabs other than 4x10's and some 2x12's, that it won't hang over the sides, but between the two that you asked about, with a 400 watt head, i'd go big (1515/66).

+100

I'd use the 1515/66. Just because, well, why not? With a 400 watt tube head, subtlety is already not really a concern.

Thats why I went with a 1515/66 with my Classic 400

The 15/6tube is designed to accomodate large tube heads (26") turned on its side.

Two of these stacked would be the widest configuration, and generate the most SPL. Reverse baffles so you get the mid drivers next to each other when they are stacked.
 
Well, I have plenty of other amps to use and I make my own speakers, but, one of my backburner projects, after finishing several other things, is getting my Classic400 tubed up and in use. It's Peavey's monster 400 watt tube amp like your Marshall. I think I've almost sold myself on doing a 15/6 tube for it. That amp has the juice to make one sing and would be a 1 cab solution for me, any louder than that and I put the whole band in the PA. I'd consider that for your Marshall, unless you don't have an 8ohm tap, then do 2 of them. Whatever you end up with, if you like grit/overdrive, leave the tweeter out and just do a 15/6 of some sort. If you don't mind the big head on small cabs look, a 1212/6 might actually be a better solution sonically depending on how big your gigs are. They're about 3db lower SPL, might be able to turn that thing up to where it sounds good without outrunning the PA.;)
 
Which one to sit under my VBA 400 12126 or 151566. I'd like to build one but which one ?

1. Measure your usual pack/haul space.
2. Compare to dimensions given on fEARful website.
3. If 1515/66 fits, build that.
4. If not, but 1212/6 does, build that.
5. Note that 15/6 will fit in same or less space than the 1212/6, so at least give it some consideration.

That's what I did anyway, and I have a 1212/6. Love it. Occasionally still pine for a 1515/66, simply out of pure power greed. You know, the little boy inside a guy's head that says "I want the BIG one!".

But I don't actually need one, and the 1212/6 really is a perfect size for my purposes for so many reasons. Number one, it fits in my car at the same time as 3 child seats. Perfectly, with only about 2 inches to spare in the longest dimension. Second, it is just narrow enough to get through some narrow spaces it needs to go through regularly, without turning sideways. Third, it is plenty big/loud enough for anything I've needed it for. Including rock/metal/etc without PA support. (Indoors at least.)

They're about 3db lower SPL, might be able to turn that thing up to where it sounds good without outrunning the PA.

Well, maybe. Better be a pretty good PA. :D

But seriously, yeah... that might be one more thing to consider. Cranking power tubes to glowing hot gooey golden goodness might be a little overwhelming for anybody in the line of fire of that double 15 bad boy. But... that amp through a 1212/6 wouldn't be anything to sneeze at either. :bassist:
 
1515/66 is 24" wide. One inch hangover one each side is not so big of a deal--take a look at people who have racks that go a little wide.

If you really are concerned about a perfect match, you can go with two 15/6 Tubes, but the 1515/66 is the MOAC (mother-of-all-cabs).

There - all fixed. :hyper:

What would happen if you built the 1515/66 2.33" wider?

You could always reduce the inner dimensions with glued in/painted styrofoam or wood or some other appropriate material.
 
You need to go hear what a 1515/66 can really do. I though I knew, but was beyond impressed when I picked mine up. My head is 100lbs and wide, and I dont think there is any instability in the set up. I even have a second peavey SS head on top of that, almost 200 pounds perched up there. If you are unsure about it all get a 15/6tube first and see how you like the sound. If you need more a second 15/6tube reverse baffle or a 15sub both pair well.
