With respect to the box shape...and goes for driver positioning as well. 2 boxes of the same internal volume and tuning will give the same lowend profile with identical drivers. There are however some difference in "character" or overall frequency response due to the differing distances between the panels. That puts cancellations, etc. at a different frequency. In most common size bass cabs, this ends up being somewhere in the midrange. This will show up in frequency response measurements and if done as an example, with no damping in the cab, can make fairly obvious differences to the ear as well. In a good design like these, good dampening mitigates those issues to where you'd be hard pressed to hear those differences, especially live on the gig. If one wanted to go overboard with it, additional filtering in the crossover could be manipulated to make the 2 measure almost identical, and put you in a spot where any differences heard by the ear/brain would be mostly imagined.

Talking minute little stuff here. The stuff that after some point just isn't going to matter.

Dukes crossovers have more parts in them than some simple amplifiers. Whatever he puts together is going to be smooth.

I remember taking a flashlight and looking inside my TC112 when I first got it. I thought 'what the heck IS all that stuff in there'

The most obvious, easily heard difference is in the depth of the cab. That is the most direct bounce back from the rear wave off the back of the cone, off the back wall that is perpendicular to it, and back to the cone, though all the other dimensions also affect it to some degree.

Again, good design will mitigate this mostly, and these TC designs are made with an eye/ear towards the response all around the cab, not just what's coming out the front of it. Hence the port placement, rear-firing tweeters, etc. They really go above and beyond most MI designs.

Yeah, saw some photos in the bass gear mag. article thinking " all that needs is a cord to plug it in ". Looks like a powered cab in there.

Duke's crossovers are really *the* example of a no-holds-barred, uber high quality crossover.

will33 · #**706** 12-26-2012, 10:31 AM

Our local TB'er Passinwind has some DIY's that kinda look like that. Those are about the only 2 I can think of that are that involved with all the filtering, etc.

After reading about it for months, chewing the cud for a few more then taking the plunge, I hope to get one of Mike's composite narrow TC15AFs next week. I wonder if this will be the last of the original driver set ups. Now I'm back home for a while Stateside, I'm looking forward to giving it a work out with precision and upright together with a SM 9.2.
Now with the new rig the whole joint will be able to clearly hear my sloppy intonation from two years separation from the upright!!

Have any of the new TC112s with the stock 8-ohm woofer shipped yet? I'm curious to hear a review on how they compare to the original TC112s.

Thanks,

Bob

Still waiting on a pair of Hathors. I am having a gear induced episode and the wait is killing me. Not having a gig until february doesn't help. This time of year in the north country is pretty sucky.

I do not think those cabs are on the production schedule at this point (could be wrong, but I don't think so). The TC212 was introduced as a replacement for the TC115, which is no longer available due to Eminence OEM driver order size requirement (i.e., they requre a LOT of drivers to be ordered before they will do an OEM).

As far as I know (based on a somewhat recent post by Duke), there are still plenty of 4ohm OEM 3012LF Thunderchild drivers available, so the TC112's are still in production.

The new 8ohm 112 with the stock 3012LF will, just like the TC212, be introduced (I assume) when the TC112 production is winding down.

I would assume the future 112 will be voiced just slightly lower, and of course, have lower efficiency due to the 8ohm impedance, and I would think would be a slighly larger box due to the requirements of that stock 3012LF driver.

I think Duke also mentioned a new 115 based on a the Faital driver, possibly available in Feb ?

Yeah, that and the Hathor are a bit of a different line all together, attempting to build a more 'traditional bass backline' sounding cab with that warmer top end and more midrange complexity, etc. Not sure of the status of that.

RColie · #**713** 01-04-2013, 08:23 AM

Here's the latest I've heard (my apologies to Duke if I get something wrong):

Original TC115 4 ohms: no further orders are being taken. Existing orders will be filled. Duke is saving some woofers for warranty repairs.

Original TC112 4 ohms: Duke still has woofers as well as recone kits, and he's still accepting orders.

New TC115 with Faital woofer offered in both 4 ohm and 8 ohm versions: under development, should be finished later this month. Will be voiced similar to the original TC115.

TC212: per many posts above, this is shipping.

New TC112 8 ohms stock 3012LF: Duke started taking orders about one month ago. I don't know if any have actually shipped yet, but I'd be interested in reviews if any have shipped.

Ah, cool on the TC112 8ohm. Thanks for the clarification on that. I guess the original TC112 is nearing the end of its production cycle relatively soon. That is a shame, since the 4ohm and very small size really made that cab a dream with a 500 watt micro head.

There's been much talk of an off the shelf 4 ohm 3012LF, so I'd guess that some form of 4 ohm TC112 will likely stay in the line one way or another even if Duke can't swing another OEM driver buy.

That would be cool. Many times, the 4ohm/8ohm thing is not that big of a deal, but for the design logic of the TC112, which is to get a small, single cab solution that will handle almost any gig and put out real low end at volume, and the fact that the cab is, at best, moderate efficiency, that 4ohm version opens up a LOT of options for micro head amplification in that 400-600 watt at 4ohms spec.

+1, being able to use a tiny amp can be a huge bonus with this class of cab for some of us.

RColie, thanks for your detailed reply above. You got it all right.

Passinwind, I'm not aware of Eminence moving ahead with 4-ohm Kappalites, but it would be fine with me if they decide to do so.

I'm really partial to your OEM version in any case Duke.

+1.

As with any gear change, it took me a while to relearn my rig again after switching to the TC112AF (I'd been using my previous cabs on and off for 14 years).

But now that I have everything dialled in, I have to say that I wouldn't change a single thing about my Thunderchild.

Not. A. Single. Thing.
