Fearful thread part 15 (/6?)

Played a private, outdoor gig yesterday for a corporation, and they rented a nice professional stage for us. Before the show, I was out in front of the stage, probably about 75-100 feet away, and my guitarist, who also plays bass, was noodling around on my bass. At first, I noticed the bass sounded good, but attributed it to the PA... until I realized it wasn't going through the PA at all. I moved a little more to the center of the front of the stage, still a good distance away, and was pleasantly surprised with 1. how well I could hear the bass, volume-wise, and 2. how clear and present everything he was playing came out of the cab. I've been playing with IEM's lately, so I don't get much of my sound through the cab as I used to. Very happy with the fEarful and the tone I'm getting!
 
As someone who grew up in an auto parts store, please ask for 3/8 fuel line. Some of these Advanced Idiots will look at you like you have two heads and tell you there is no such thing as a 3/8 heater hose. I would go with 5/16 personally.

I went with a much higher diameter- about 1" outer diameter, and the wall is pretty thin, the inner diameter couldn't be less than 7/8".

But MSU has kindly offered to forward one of the kits from exxi, so I think that's how I'll handle this.

Thanks to all for the great advice and support. This past weekend I chickened out and took my Genz UB212 out the gig instead of the new fEARful, but it turned out they *had backline* that the BL didn't tell me about. A Fender 100 Rumble combo. It worked ok- actually plenty bassy, it was really lacking in the mids of all things.

For the jam I used my GB 212 (so we could have 2 bassists) and I dug it ok but was already missing the deep solidity of the fEARful that I'd been practicing with all week. So this Wednesday I'm taking the fEARful for the first time to a gig in a notoriously tough room- it's small and tends to be loud and indistinct. I'm hoping the fEARful's combination of hi-fi clarity and deep solidity will let me keep my volume down and thus keep the whole band a bit quieter. :bassist:
 
It's way more fun to take the fEarfuls and offer to backline. Share it around, they can take it. I've taken mine over to the local blues jam and really enjoyed listening to the feedback. It was an eye opener.

They had a Di going to FOH. Out in the room, it was not at all what I expected, not at all the fEarful sound, and the guys were not impressed. Note: there's not much a FOH guy can't ruin. This guy regularly turns great bass gear into mud. Really loud mud.

Once the other guys got their turn on stage, the feedback was much more positive. Not only was the stage volume lower and more comfortable, the bass sound was super clear and responsive.
 
The fEARful 15/6 kicked a lot of booty at the first gig I used it at. I don't think it succeeded in keeping the volume lower though because it sort of drove the drummer into a frenzy, then the rest of the band followed, and I had turn up for self-intelligibility. But it sounded great. The low E has a pretty serious buzz, which turns out, upon closer inspection here at home, to be one of the circuit boards mounted on the port shelf. The low and mid A also buzz the grill, but that was not as intrusive at the gig, although I did hear it immediately when I listened for it during a louder rock tune. So I'm working this weekend to try and damp at least those two big buzzes on very important notes.
 
I know it's more complicated with the 18Sound mid and its related L-pad resistors, but can't this problem be eliminated by simply mounting the crossover components directly to the cab without using a circuit board?

In this 12/6, I glued and screwed the coils and turret board directly to the shelf without any damping/cushioning. Even competing with with 2 cranked half stacks I've never heard any vibrations from inside the cab.

That's a progress photo while building my 2nd 12/6. The cab hadn't been lined at the time. The finished cab had damping material on the shelf, around the coils and turret board.

I see no benefit to placing damping under the X-over. No (air) pressure waves getting there, let alone bouncing back.
 
I leave the port shelf clean of dampening and stop the polyfill at the port level on the back and sides. Everywhere else gets a thick treatment of polyfill.

I use a scrap of ply wood as the the circuit board and strap everything to it with zip ties. Once it's all together, I screw it down to the portshelf, the zip ties are my spacer/isolater. Never a buzz or rattle. I like this method because I can pull the whole board out to mess with it, if I ever need to. Never had to yet.

Nothing wrong with that. When I built my first cabs, a pair of Bill Fitzmaurice Omni15's, I mounted the crossover components right on pieces of bracing close to the drivers.
