Fearful Part 14: one better than 13!

man, that GK MBFusion800 has much going on with lights and push-button knobs. i'd almost pay the premium of the Puma to have fewer knobs.

any thoughts on a Walkabout with a 15/6? seems a bit low in the watts department, but it is a respected head otherwise. i ran a google search for "fearful walkabout bass" and got nothing useful in my top results (TB threads did pop up). the Mesa shop is just down the road, so i could pop by for a try.

+1 I'd rather the manufacturer focus on the real stuff, and not all the bling. Nice head though, plenty loud with the 15/6, and a bit 'rougher, grindier' than the very smooth, crystal clear, clean Puma.

Walkabout and a 15/6, not even close IMO.... don't bother. Great head though.

On a 15/6 try a slight boost at 1.5k & a notch at 4.5k - leaving 3k alone. Roll the lows up/down to taste.

After having spent some time with the MB800, my personal opinion is that the lights and push-button knobs are brilliant and offer up real functionality in a very intuitive fashion (once you get past the pretty colors). You get great visual feedback as to which channel is active, whether or not the limiter is engaged, whether or not the limiter should be engaged, whether or not you are clipping the input and should hit the -10dB pad, etc. IME/IMHO, this is not "bling" at all.

But, as always, YMMV.

how are those knob lights in bright light? if you are in a dark bar, that is one thing, but if you are playing in daylight hours, possibly even outside, are they still reasonably visible?

btw, tonight is the first time i've been able to sit down and fiddle with EQ and jam along with the stereo at a decent volume for a decent amount of time. man, this cab just kills. the hype seems justified. i still haven't busted it out in a band setting, so i need to hold back on judgement, but i have zero regrets so far, and confidence this thing will hit a home run. it is a monster.

right now i can'y get enough of the:
Nash PB63 --> Mesa M6 --> 15/6
oooh, spooky with the three "6" combo!

I have not tried them outside in direct sunlight, but in a well-lit room, you can still see which ones are blue vs which ones are white (this tells you which channel is active), and you can definitely see if the -10dB pad or the limiter are flashing red (indicating the need to engage them). It's possible that the blue/white distinction would be hard to tell in bright sunlight, but the red - which is ultimately the more important visual cue, at any rate - is still going to be visible.

I have to admit, at first it just looks like a fancy light show, and a show without any real added functionality is definitely bling. I don't see that as being the case, here. In fact, in his technical review, Tom Lees was impressed by the functionality which the lighting scheme adds to the equation.

Even without the lights, though, the push-button functionality behind those knobs does add usable features without taking up more real estate, and I like that approach, myself.

the M6 is a whole new animal. the pulled bass knob setting is actually useable. it wan't at all practical with any other cab i tried (a limited population, but includes the PH115 and PH212). now, it just sounds glorious.
gain at 10:30, bass pulled and at 1:30, mid at 11, voice on 4 (slight mid bump), treble at 1, master at 9. volume adjusted to "reasonable" on the PB63, and the tone turned down around half way. right hand plucking position adjusted as needed for "definition."

Quick question...

My 15/6 that I am building has just had the dampening material put in. The spray on adhesive has too strong of an odor to keep inside my condo (bringing it in would really upset my wife and is not an option). Is leaving the cab outside overnight going to hurt the crossover? I'm not worried about rain as the balcony is covered enough. However, I am worried that perhaps there could be condensation or something that may harm the electronics.

Thoughts?

If you've got it protected from precipitation, then the only way you'd get condensation is from a sudden rise in temperature accompanied by humid air. If you are concerned, make sure that you don't use it for 24 hours after bringing it inside, and keep a fan blowing past the electronics to dry them. Probably overkill, but you should be safe. People have actually dried out phones that fell in the toilet. Some of them work afterward, others don't. Unlike a phone, your cabinet doesn't have a battery applying current, so it probably wouldn't be harmed. Think of all the stuff that people find in basements. Unless they were flooded, they usually still work despite humid conditions.

For my current 15/6 build, I bought the 7$ Dayton wave guide and am installing it now despite not having bought the driver or crossover yet. I'll plug it for now and worry about adding the tweeter later.

I'd like to do the same, but I'm having trouble finding something with the correct 18 threads/inch to match the horn. Did you end up using a dead HF driver, or were you able to find a source for something to plug the horn?

Thanks,
Marcus

I ended up just ordering the hf driver. You could try an auto parts store for a radiator drain plug the right diameter- the expanding rubber type with a wing nut that you tighten...

I had planned to use a chunk of foam rubber in the finger of a black rubber glove. Stuff a large enough chunk in to expand the glove larger than the throat. Compress it to remove all the air, hold the open end closed while you fit it in the throat, then release the open end. When you do, the foam will expand and form a tight seal. The foam alone wouldn't be air tight, but with the rubber glove around it, it is. You could probably use a balloon or even a piece of trash bag, though the latter might be prone to buzz.

If all you are taking about is a little condensation, it shouldn't be an issue. I would think your only concern would really be oxidation on your i/o contacts. The capacitors and resistors are sealed, and the wire in the coils is enamel plated. A little extra oxidation on the bare leads, solder and traces might add a slight bit of resistance over time. But these are big discrete components operating at higher voltage and current than what is going across the tiny little smd components on a cell phone board. Still, you could lay a towel over the crossovers to minimize the chances of moisture condensing on them.

Thanks for the suggestions. That gives me some options.

well, the grille buzz i've been hearing is changed by playing with the cab on its side. it no longer vibrates when i play Ab/A/A#.

i also found i can lift it one handed pretty easily. the balance seems to depend on the orientation of the 6" driver (ahead/behind you, and higher/lower relative to the ground).

Doesn't sound like it is your problem, but the 3015lf has enough excursion to extend past the gasket and hit a flush mount grille. I haven't had the issue with a fearful and a round grill, but I have with a larger PA subwoofer using 3015lfs.

If the grill is the issue, 'floating' it with thin weatherstripping over the stock gasket will take care of it. This stuff works great and is a flat black that blends in well (unlike what you'll find for windows locally): [Invalid or Expired Link Removed]

Thanks, much Robby---I was just going to suggest the same thing. The excursions on these speakers is insane! I just started doing that as a preventative measure. I've talked to Greenboy and Duke and both concur that they've had more problems with grills since using the LF's. It's a bit of rethinking implementation to insure against any possible rattles, hitting the grill etc.. Even with the 8's I started using gasket tape because those stupid little drivers have 8.1 mm xmax! Also, I find that the gasket tape insures against potential grill rattles.
