AudioKinesis Cabs Part VI...

Finally got my Hathor 1203 yesterday...you may notice something different!
Always fascinating to see the AudioKinesis line evolve, often in incremental fashion. However, the original designs are solid from the start, offering great tone and value even as version 1 of x. Enjoying the "old" as well as hearing of the new. Thanks, Duke, for your commitment to the sound of bass, and bass players.
 
That's why gawd invented the Sawzall...

So me with a Sawzall... how long before I'd have to change my name to "Nubs"??

I'll tell ya... multiple ports on the 1203... I'm jealous!

Any day when I can make Mike Arnopol jealous is a good day!!

Seriously, that was very considerate of you to come on here and post that, Mike. You are a true friend.

Mike Arnopol is a factor in pretty much everything I do these days. He's either helping me with something, or I'm busting my butt trying to compete with him, and usually it's BOTH! I try to make him have to "work for it" too, which doesn't happen nearly as often as I'd like so I really get a kick out of it when I can make him even a little bit jealous!

Duke, did you add or modify any internal bracing due to this new port design? Did this change have much effect on the rigidity of back wall of the cab?

Excellent observation! Yes, the three port cut-outs + two dish cut-outs = plywood Swiss cheese. So I do indeed have little solid wood reinforcement boards in between all of the cut-outs. When I'm done gluing them in place the stiffness is pretty much restored.
 
Tonight's hit. 300 seat theater, Raw Theater awards show hosted by French and Vanessa Stewart. Just the H1203 and D800+, not FOH. Half hour set of jazz after house opened, then we were the house "orchestra", vamping winners on/off stage as well as doing a couple of musical numbers with dancers. 1pm call, cue to cue rehearsal from 2-3:30, then again 4-5:30, dinner break, then doors open at 7pm. Bass sounded awesome, French was hilarious, and we closed with a rousing version of I Will Survive. After about 7 hours of mostly non-stop playing, the final disco octaves were killing me :D

The LA Theater Center is in an old bank building with a labyrinth underneath including passing through the old safe door to get to the bathrooms. It reminded me of Spinal Tap ("Hello Cleveland!")

Three ports open = 54 Hz tuning frequency (fartout resistance still looks good); +.5 dB @ 82 Hz; - 2.5 dB @ 62 Hz; and -10 dB @ 44 Hz.

Plug one port (two ports open), and the tuning is within 1 Hz of the single 3" port, about 45 Hz. We're -.5 dB @ 82 Hz; - 3 dB @ 62 Hz; and -10 dB @ 41 Hz.

Plug two ports (one port open) and now the tuning frequency drops to 33 Hz. We're -2 dB @ 82 Hz; -4.5 dB @ 62 Hz; and -10 dB @ 40 Hz.

Plug all three ports (sealed box) and we're -4 dB @ 82 Hz; - 6.5 dB @ 62 Hz; and -10 dB @ 47 Hz.

So in English, we have a little bit bigger low end than with the single 3" port when all three 2" ports are open. We have essentially the same low end as the single 3" port when two ports are open. And with one port open we have one more intermediate step, with a tighter low end, before we go all the way to sealed box mode.

Duke, can you comment on what (if any) effect this would have on mixing a new 3x2" port 1203 with an older 1x3" port cab? It sounds like with either all ports plugged (sealed cabs) or 1 port plugged on the new ones (same tuning) they should behave the same, but with all ports open on the new version would the slightly different tuning between the two cabs lead to the low end being less defined, or is it fine?

I think having a slightly different tuning frequency for the two cabs (either zero or two ports plugged in the new one) might even be the best option. Briefly, spreading out the port tunings a bit should result in slightly better pitch definition. You can read a longer explanation in the bottom few paragraphs of this post, where I'm replying to something engedi1 noticed when using cabs with different tunings (Hathor 1203 + Thunderchild 112).

This is fascinating! I stacked my little GenzBenz Shuttle 10T cab on the new 1203 (2 ports open) and it sounded amazing! They are surely tuned quite differently.

Also, Duke, where did you get that wonderful quote on your sig?

Sweet!

I don't know. It just popped into my head one day, a few weeks ago. I think it's my subconscious putting into words something that I need to work on. It hit me pretty hard, and I decided to put it into my signature mostly as a reminder to myself. It is NOT something that I have a good track record with, but if it's out there "in public", it's like I have a better chance of remembering it, and a bit more incentive to try to live up to it.

If enough people borrow that for their own quotes [signatures], you'll be well on your way to starting a cult. How much acreage do you have up there in Princeton?

Well now it's really in public, I put it on my FB page because it hit me so hard. I'll give you credit, thanks!

Fantastic. That's an even better result than I had hoped.

I definitely need to talk to you sooner rather than later about getting my 1203 a friend.

My cult only has one rule: Membership is permanently limited to one. So if anyone else wants to join, that means I have to leave.

Wow... I don't know what to say. Thank you. But you are more than welcome to leave my name out - if the content really is that good, attaching a person's name to it might be a distraction.

Yes, I get it...makes sense.

Any chance you could take a stab at approximate tuning frequency of the GB Shuttle-10T cab? Outside dimensions are
12½" x 14" x 11¾". Or at least why they interact so well? I know you've already kind of covered that but...any other thoughts? I'm able to stack them so that the slots for the tweet are still open.

Thanks!

I had an Hathor 1505 side by side with an Eminence loaded MAS 112. Very close in total output. MAS was slightly warmer, and a bit more polite. 1505 is a Killer Rock cab and by far the hardest hitting sub-40lb box I have had the pleasure to try.
I've been seriously considering a Hathor 212 lately because of it's percussive and solid low end but am torn between 3" versus 5" mids. I play mostly rock, blues, funk, and modern country and was wondering if the slightly louder and growlier 5" mid would be a better fit. There don't seem to be many Hathor 212's out and haven't heard of one with a 5" mid yet so there is no user feedback. I don't need to hear up to 14k with a bass but like to have the mids stand out if needed. Thoughts on this?
