fEARful part 13: the bad luck's done, son

[monsterthompson]

OK. Looks right now!

Thanks for the info. Is that your cab in the picture? Do you have tilt-back casters on it? If so, do you like them? I'm a tall guy so kind of imagine myself all bent over trying to roll a 1212/6 with tilt-back casters. And that's no fun.

not mine, but it makes me drool. i'm still shopping and don't own one yet. the wheels on the 36" high cab have me thinking rolling might beat lifting on the 30" high 15/6.

Very short Cliff Notes version, perhaps scary tech types can just suspend disbelief and derision for once: the crossover matches driver impedances by changing impedance in line and/or in parallel with the woofers and the mid/high drivers as frequency goes up or down. That allows the drivers to share primary output duties safely and (hopefully) gracefully.

Thanks. I love reading and learning about this stuff, but sometimes it's easier to just ask.

I love Cliff Notes!

I'm 6'2" and have no probably rolling the 1212/6. Unless you have really short arms, you shouldn't have to stoop

+1 on rolling a 1212. I have tlltback wheels and a top corner handle, as well as side handles for lifting. I put my wheels as far apart as I could get them, I have seen some builds that have them much closer together. I think that would let it "wobble" back and forth over less than smooth terrain, testing the corner protection.

I use either a Shuttle 9.O, or just recently a Crown XTI-1002 with a Demeter preamp. The Shuttle does a good job, but I'm not sure how loud you would grt or how much headroom you would have with the 6.0.
I'm sure that it would sound great, but would be limited as to available SPL.

I have never used a tube amp with my fEARfuls, but I am an old school player as far as using a four string with flats, and fretless about 50% of the time.

You got this from WinISD didn't you? Admit it!

Thanks. I'm also 6'2". I had an Ampeg 410HLF for a very short while years back... I have nightmares about rolling that thing around. It was just short enough to really suck. Also have nightmares about how that cab sounded,, but that's another story.

Forgot to add: because the wheels protrude below the bottom edge by about an inch, I added a 3/4" spacer to the rubber feet. This way, when it's not tilted, the feet are taller than the wheels, so it won't roll around while playing.

So it's actually almost 2" taller. That puts it at about 38" now.

That's one of our cabs we built for a customer. It does have tilt back casters and it makes very easy to move around, especially being so light. It is a tall cab, remember. I find the 15/6 to be on the cusp of having to bend down to move it with casters. Anything smaller and it would be better off using a hand truck.

Given the weight of the 1212/6, couldn't you just kinda throw it from the car to the stage?

Maybe put it on a paper airplane?

Hey, 40 lbs is a lot after two sets and x amount of beers!

That's close to sig worthy. Love your work Robby. If I ever need another fEarful built I will be hitting you up.

Wimp!

Obviously you need one of Greenboy's famous 8" fEARful rigs.

I've decided to build two fEARful 12subs, and a headcase for the 6" mid and crossover. Weight reduction is the only reason I'm building new cabs, and I'm committed to 12subs, not 12/6s or any other enclosure. I want a rig I can lug around when I'm 70 (only 9 years away!). I'm not here to ask for weight reduction suggestions - that has been covered in another thread.

I'd like to have the flexibility of using the headcase with one 12sub for quieter gigs, and the same headcase with two 12subs for louder gigs. I play flatwound strings, I don't slap, and so I don't know need a lot of top end, but I do want some added mid presence. I have a mono amp, 500W @ 4 ohms.

One possibility is put an Alpha6A and a 12/6 crossover in the headcase, which would be ideal for gigs where I only use one sub. For louder gigs I would plug one sub directly in to the amp and the second sub into the headcase, which would then be plugged into the amp. Am I going to run into any nasty phasing issues as a result of some mids coming from both the Alpha6A and the 12sub that is plugged directly into the amp? Also, will the Alpha6A give me enough output when I use two 12subs? I'm really interested in how this setup will sound, more so than how it looks on paper. How many guys are using or have used a 12sub with a 12/6, and what is/was their experience?

Another possibility is to put a 6ND410 and two crossovers (a 12/6 and a 1212/6) in the headcase, with a switch (four pole, double throw?) to connect one crossover or the other to the 6ND410 and headcase jack plate. This would be more expensive and heavier, which I'm hoping to avoid. Also, would I have to add an L-pad to attenuate the 6ND410 output for gigs when I'm only using a single 12sub?

Would a Zobel circuit solve my impedance matching problems? Is there another possibility I haven't considered?

Perfect. Thanks. I just registered, waiting for admin approval.

My 2 (15/6/1) cabs from Ron Anchak came in yesterday!

Really busy at work but got to play them for an hour today.... sooo transparent and just amazing!

The low B is just thunderous, articulate and tight all at the same time.

Once my fEARful badges come in from speakerhardware I will post some hirez shots and do a complete review.

If you are building your own and weight is important check into Italian Poplar aka Eurolite. You should be able to get it below 35LBS. Heck there is one TBer who built his 15/6 out of IP and his came out at 36LBS.
