That's what Duke told me. He says it will get more volume from my 300w Walkabout, similar to what a 500w head would do with the TC 112. I love my Walkabout and don't really feel amp shopping, so I think I'll wait for Duke's 115 version.

Yes, the 115 will be 4 ohm just like the 112. Re-reading my emails, Duke said he has some things to get in order before he decides to go ahead with the 115 version. That was back in mid-December. I'll post any updates if I hear anything.

i'd be extremely shocked if he used a mid cone. duke is all about the mid horn and is on a mission to change people's minds about paper cones for mids.Is he going with the big PA type horn, or a midrange ?
It is a compression driver like the 112, only crossed over lower which dictates a more expensive driver. The 15" driver is a custom high efficiency 4 ohm version of the 3015/3015LF. Cabinet size would be 25" tall by 21" wide by 14" deep and it would weigh just over 40 lb. The idea was to maintain a similar low end as the 112 but with the 15's increased efficiency. I'm all about it! First in line....![]()

As someone who's eagerly awaiting the arrival of his ThunderChild, this is great news! I'm sure I could find room for another one of Duke's creations!
But there is one important piece of information missing here... what will Duke call it???? I, for one, vote for ThunderBigBrother.
I would recommend the Thunderchild12 and Thunderchild15. They will both look the same from my understanding, and that is a simple way to communicate it!
I'm excited about this cab. I had very little interest in a large 212 cab with the stock 3012LF drivers (not my thing), but I like the TC112 enough that I would welcome a version that I could use on my largest, loudest gigs that was still relatively compact and lightweight. I would think the 115 could carry that load!
That being said, the 112 model should be enough for most players in most situations... simply stunning performace, and amazing tone/size/low end/weight/volume ratios.
I'm wondering how this will compare to the fEarful type 115's. You've sampled enough of them, care to take a guess? I'm especially interested in how the high end will compare, especially with the tweeter/ mid models of the fEarfuls. Obviously, the 4 ohm advantage is there, but I'm wondering more aboout tonewise, mid/tweet vs. big horn.
It's too bad a cloth grill would compromise dispersion slightly, as I think a "traditional"-looking Thunderchild would appeal to those who are a little more willing to allow the psychoacoustic effect to affect their perceptions.
Duke has thoughtfully given us more carry options with the 115 since it is a little heavier. It will have side mounted handles in addition to a recessed padded top handle like the 112.
