AudioKinesis Cabs Part VI...

Don't you want/need the 3" to "fill the gap" between what the 12" can do and the sweet spot for the horn?

If all goes according to plan, the 6" cone mid in the Hathor 212 will do the heavy lifting from the grindy zone all the way up to where the tweeter horn takes over. I'll be juggling several tradeoffs in choosing exactly where that upper crossover point will be. I'll probably use the same horn and compression driver combination as in the 8-ohm Thunderchild 112, and the higher crossover point will protect it from the higher wattage it would otherwise see.

Just seems that there is something in the upper mids that the 3" does that a horn or tweeter can't - at least not with the same flavor. So if you really want to get wacky, 12-3-horn, with both the 3" and the horn switchable. :D

Well without the mid we'd have a hole in the response, and if we overlap the two upper-range drivers, we get unexpected and undesirable interactions. What sneaks up and bites us in the backside is the phase response. When two drivers overlap a lot, but have different rolloffs at either ends of their range, they will go in and out of phase with one another and we'll get dips in the response that we really can't eliminate.

As far as what that 3" cone (or any good cone) does in the upper mids, I agree! That's where the Hathors beat the Thunderchilds for electric bass, if one is looking for a bit of deliberate voicing in their bass cab. If I do a three-way, the crossover will be high enough that upper mids will be done by a paper cone.

Hmm, that will be a very interesting cab. It is almost what I have going on right now when I run the H1203/TC112 stack (except for the 6" part)

So 2 1203's will not equal the upcoming 212?
Click to expand...

While there's really no reason not to make the 212 equal to 2 x 112, in this case I think there's an opportunity to push into new territory a bit with the 212 version.

Part of what happened is, a very useful little part recently became available that I think will make it practical for me to combine the Hathor's open-format midchamber with a good little horn-loaded compression driver. I'm not a big fan of the more compact bullet tweeters because they inherently beam pretty badly... a 45 degree pattern width (-6 dB at about 22.5 degrees to either side) is pretty much the norm for a bullet tweeter, but the baby butt cheeks horn w/compression driver that I use has a roughly 90 by 90 degree pattern, which is imo a worthwhile improvement.

Anyone have experience with upright through Hathors?
Click to expand...

My understanding is that the Hathor 1203 is okay but not great on upright. I'm working on a small cab for upright bass... or will be again hopefully next week. I lost several days to a bout of stomach flu, still not back up to speed yet, but will get back to work soon as I post this. There's two empty Hathor 1855 enclosures stacked in the living room that are calling my name...

I'm aware of quite a few posts that still call for a response from me, and I'll get to them when my brain is a bit less foggy, hopefully tomorrow.

Wow, THANK YOU, Tom!!

Yeah I was pretty much blown away that the Swarm was selected by the staff of The Absolute Sound for Product of the Year in the "affordable" subwoofers category. Credit for the asymmetrically distributed multisub concept goes to my mentor Earl Geddes, who let me use his idea for free.

The Wide Body option is definitely amp-width, which is why I went with that option for my TC115AF:

Great...thanks a lot @tombowlus. Now I have an extremely unreasonable and (at the moment) un-fulfillable desire for both a Reeves (which I've been admiring from afar for a while) and a AK. And I have a perfectly nice GK 2x212 setup right now.

Dang it.....
