The ROCK DESTRUCTION continues! Meet "General Sherman" (JGR's ported 1810)

[JGR]

I had actually pre-drilled the holes - that particular batch of screws was just really soft, terrible junk. For most projects these days, I just order stainless hardware from McMaster Carr.

[JGR]

So I've been doing some more torture testing to explore the limits, but I think I'm getting punishing more than the cab from the insane levels.

I play heavy strings on my basses, so I just tuned the low E down to B and hammered away at full tilt through the DB680 with the deep switch engaged in the "++" setting, which is a big bump down in the 30's, and the only thing that happened was all the pictures and stuff I'm the room shook. I think we're good to go!

[JGR]

Just shot another quick video before I am silenced for the day (wife has to study!) using my Fractal Audio Axe FXII on the SVT setting. Really feels like a tube head with that big low end, and the cab reproduces it beautifully. I was running into the SWR Power 750 which does a good 750 watts into four ohms, and I'm pleased at the overall output, even coming from the 2500+(whatever I can actually get out of my 20A wall circuit) of the QSC. I'm kind of gassing for a Mesa M9 again because I think the huge low end would be a lot of fun through this thing.

Nice Jon. I have a Sonic 18 with an EV in it and surprisingly, it really holds well with a 5er.
I guess I'll have to dig it out as well......

Completely awesome concept and tone. Love it. When I see all the fearful stuff I always wonder why nobody is doing a 15/8 or 15/10. The mids from 10s are so familiar and exactly what most of us want.

That's because it is.

You don't have to have Ken come up. I have a set of 113's on one of my Musicmans that we can drop to C.

Funny that JGR has now done both a 15/8 and an 18/10

So, should I come up next Sunday? Bring a few active basses.... and earplugs? :-)

I can bring one of those big tube heads too...

Of course you predrill the holes, then you put wax on the screw.

Man, I wished we lived closer, Jon. I think it'd be a blast to hang out with you!

You're always welcome here - bring it!

Indeed sir! I've been trying to figure a way to pay a visit to your neck of the woods for a while now. I have a wedding in Columbus in September.... I think a detour is in order??!!

Anytime! Earplugs? - oh hell yes!

[kringle77]

You are sure one scary SOB JGR. That 10 looks and sounds alot like the one in my lds 810. I really want to try the eminence copperhead someday. You are awsome man!

HA! Thanks Chris.

Before I got my crossover built, I was testing out the 10 in one of these boxes:

http://www.parts-express.com/pe/show...number=260-642

...using the high pass crossover in my DB680 because I hadn't got around to building mine yet. Just evaluating general behavior, tonality, etc. Anyway, I don't think the DB's crossover is very steep, or maybe just the frequency dial is off, but I got a little over-zealous (imagine that) and creased the cone in the current driver. I was putting 775 watts into it so go figure.... anyhow, it works fine but needs to ultimately be replaced. I may have roughed it up a bit too much. It's much more protected with my crossover, but it's showing some mild signs of unhappiness at the extreme end of things due to the initial beating I subjected it to. Now that I've verified my crossover, sensitivities, impedance, etc.. I figured I'd give a few more 10's a whirl before I settle on something. Have two coming this week and a few more candidates if those don't work out, but it adds up... There are some pretty good choices though. The 8's were slim pickins by comparison.

Great tone!

Here's a guy building a very wanted preamp with a Fractal. Jon, you're redefining the tech possibilities. Wow.
