The gig i'm most concerned about, is in a rented movie theatre. It's essentially a backless stage, as the "wall" beneath the screen is actually just a curtain, with a mostly empty space behind it. I wonder how well a rear facing tweeter would work in that space, with no reflective surface behind it.

You still have the primary tweeter facing forward, and the option of tilting, but that's a fair question.

I intend to try placing a reflective surface behind my cab on gigs like that. I'll report back when I get to try it, should be an outdoor one coming up in a few weeks.Sometimes I use a pretty tall 15/6/1 on shows like that -- mine use a separate top box for the 6 and 1.

I'm giving some thought to getting something like an SWR amplite, so that I can stack a second Thunderchild and power it without having to carry a full-sized power amp. It would be an extra complication, but not overpowering.

And in other ways, I think that the TC may be a better fit for my needs, than a fEarful 12/6 or 12/6/1.

I think Duke decided that it would be too costly to have two new proprietary drivers (8 instead of 4-ohm) loaded in the 212 with the neo price hikes, especially considering the instability requiring Eminence give daily quotes, which is why Duke offered to build the Thundertots for Loopee using what drivers he had. I'm sure that Duke could clear this up a little bit if the story's different. edit: I meant to say he'll be using the LFs for the 212, not imply that the 212 wasn't happening.


Also, here's a guitar-gig report. My friend played a solo guitar set for a small audience (a bit more than 30) and I could hear everyone saying how it was the most beautiful electric guitar sound they've heard, and how clear and even the sound was through the room. I also heard a number of people commenting on how they were glad to hear it in person, because they didn't think they would ever be able to get that sort of experience listening to it recorded. I thought it was worth mentioning because this seems almost like suspiciously well-informed feedback, but all of it was unprompted conversations among non-musicians who knew nothing about the cabinet.

that's good to hear ;)

what guitar amp was being used?

Yup!

The stock 3012LF will allow either a smaller box or lower extension than an 8-ohm incarnation of my custom woofer would (albeit at a minor loss of efficiency), and I think it makes more sense for me to channel my limited custom-woofer-production money into woofers that do not have a close approximation available off-the-shelf.

Very interesting!

Was he using the tweeter rolloff switch?

And the 4-ohm impedance - was that an issue?

It has a jack for an 8-ohm extension speaker so I assumed it'd take a 4-ohm load comfortably. He was happy without the rolloff filter, but I engaged it for him so he could turn up the treble control at the amp to accentuate the upper mids. He likes a fair amount of upper mids to his tone because it helps keep the part layering distinct.

The resonance from the cable capacitance interacting with the pickup was around 8 kHz, so it didn't have the usual accentuation in the 2-5 kHz range. I didn't think it'd be a good time to experiment with his distortion pedals without the rolloff, but I've used some fuzz pedals in combination with adding upper-mid coloration through a tone control and had great results, even without the rolloff. The rolloff can be helpful for clean tones too but is far from necessary. I couldn't comment on a more conventional setup on guitar but imagine the same is true. Most people would probably find the rolloff helpful with distorted tones.

Does anyone have experience with both the thunderchild and also an EA nl-210. I need a small cab (or combo) and the nl-210 is a cab I have a lot of experience with so any comparisons, both tonally and in terms of max spl, would be greatly appreciated.

If I can come up from air sometime in the near future, I'll try and do a quick comparison for you.

I was idly looking at a picture of a 29lb fEarful Sub tonight, and I found myself wondering:

What about a Thunderchild Sub, for louder gigs? Just a TC cab with no horn. Padding would need to be removed from the crossover on the top cab, to balance levels between the horn and the two woofers.

Presumably, a properly aligned pair would behave like the Thunderchild version of a fEarful 1212/6/1?

Could work. Would require a new crossover, I'd guess. And might not be as small as you might like in order to get enough airspace behind the driver.

Are we talking 4 ohm cabs with the Thunderchld woofer, or 8 ohm cabs with the stock 3012LF? The latter is a more promising candidate, imo.

Actually, I tried to do a modular system much like you describe some time ago, using the 3012LF. The problem I ran into was this: The crossover could be optimized for the single woofer situation, or the dual woofer situation, but not for both. I could not find a way to change the loudness of the horn by 6 dB without altering its frequency response curve more than I'm willing to accept. I tried several different approaches, and several different compression drivers, and wasn't happy with any of them.

The stock 3012LF calls for a lower crossover point, which in turn puts more strain on the compression driver. Then in the dual-woofer configuration, the demands on the compression driver go up by 6 dB. So by the time we've bought a sufficiently beefy compression driver for this considerably more demanding application, we may well be spending more money than we would have to spent on a pair of two-way cabs, and with imo compromised sonics. I just don't want to put an expensive cab system out there that I'm not really proud of.
