AudioKinesis 1x12 Cab Part Two

Status
Not open for further replies.
I'm not saying the rear ports act as speakers; at all, and I know the rear tweet puts out very little.
Just saying that compared to a front ported cab, with no rear tweet, there's more sonic info coming out the rear of the cab.

Also: everyone knows drummers aren't the sharpest sticks in the box. Unless they sharpen their sticks, in which case you'd better watch out;)
 
There is a fair amount of midrange that comes through the ports (intentionally). While often regarded as a no-no on TalkBass, Duke partially chose to do that to be able to get some of it in the reverberant energy, especially useful for filling the hole between 200 Hz to where the rear tweeter takes over. It's also a pretty small box :D

I remember Duke mentioning that, but I don't hear any directional midrange coming out of those ports. However, the cab sounds great, and if that helps the stage sound, what the heck!

I don't find this cab nearly as fussy with what is behind it compared to, for example, that small Bag End 15 cube, with that huge hole cut right behind the driver. That cab sounds about the same in front of it as behind it:p
 
The rear firing tweet is crossed around the same area as the horn, IIRC, something like 2khz. (correct me if I'm wrong). Which means still quite a bit of sound is coming from that thing, and it could make a lot of difference in clarity when listening from behind or when the sound is being reflected off a wall behind.

...and my understanding is, that's it's specific purpose, too.

Pretty sure that's right. From what I hear, and I could be wrong, there's a bit of content below 1 kHz coming out of the ports, noticeably less until where the tweeter is crossed over, and then the tweeter comes in at a substantially lower level than the front of the speaker. You might not want much upper midrange before the 1.8 kHz range added in the reverberant energy regardless, especially at the lower levels behind, as it would perhaps "dull" the sound out front vs its current execution.
 
Chef, really glad to hear your drummer's happy with the cab. I figure if you can each hear what the other is doing, that's good for the groove.

Something I recently found out by talking through the various port tubes in my collection is that my voice sounds less "honky" through a flared port. So while I'm theoretically breaking the rules, this seems to be the less harmful way of doing so.

And yes, the rear-firing tweet goes down to about 2 kHz. It was actually pretty hard to find a prosound-capable tweeter that went down low enough without being fairly large and/or heavy. The model I use is manufactured by Galaxy Audio, and is used in their "Hot Spot" monitors. If you look it up, don't believe their published frequency response curve; it's a pipe dream. I have to EQ it rather aggressively.
 
Cool design! I didn't realize that tweeter was crossed over that low. Man, Duke must have worked some magic on the crossover to make that happen!

As we, as users, peel back the layers, we will be of one accord: Duke is an audio genius who turned his hand to the ultimate sonic challenge and experienced resounding success that we bassists are privileged to enjoy every time we plug into a ThunderChild.

I hope, in his lifetime, he is adequately recognized by bassists of the world for his contribution.

Thank you, Duke.
 
Hey Duke
I was trying to be not-too-glowing as to not look like a paid advertisement! Actually I think that yours is BY FAR the best balance of frequency response and seamless blending of lows, mids and highs. To be honest, I don't know of any bass cabs with mids and tweets that sound as good to my ears. Interestingly, as we had spoken, I plugged one port to lower the cab tuning. I thought that the "bloom" of the notes suffered as opposed to both open. With both open there was no "bloat" and perfect control but with a wonderful bloom and thickness to the notes. One closed and the cab still sounded great, and with a little more control, but the individual notes were tighter and thinner. I've talked about this phenomena lots here as a property that seems to elude measurements, but now in speakers I think I'm getting more of a theoretical handle on. Now I'm just a theoretical dummy so correct me if I'm wrong. It seems to me that there is a perfect "sweet spot" in terms of port area that allows the speaker to move with the perfect amount of control. Too big and it sounds uncontrolled and bloated, too small and the notes can sound too tight and controlled. I think Duke nailed it. I play 50/50 between upright and electric and I think that upright is MUCH harder to get right in terms of the envelope as I've been mentioning. Before my surgery on the 28th I did a recording for NPR with my own trio for a special type of state of the art binaural recording. Loud trio. Upright, drums and SCREAMING guitar. Loud. My bass with the TC had almost perfect impact---rare on studio recordings and unheard of on 2 mic audiophile recordings. And my sound was more like a fine miked studio sound---but it was a Full Circle, Doubler and the TC. No Jaco mids. No artificially glassy highs. Everybody was flabbergasted. Sounded like me on a good day in the studio.
So Duke---you were asking what cab I was referring to and I have to say I haven't heard anything better. Louder----sure. Deeper---maybe---if you want to haul something twice the size. My buddy Dan was the owner and developer with Lakland. Everybody sent him their cabs.Or he'd buy them. I'd spend hours there goofing off and trying various amps and cabs. I know what's out there.
One word to everyone here. If you play upright or 5 string electric you must get a high pass filter to really see what this cab is capable of. With the piezo pickups for upright there is a ton of subsonic garbage in the signal. This just causes your amp and speaker to huff and puff and uses all of your resources to amplify crap that you don't want anyway. Even with electric the fundamentals of the B string you don't want anyway. NO commercial speaker that I know of does 30 hz. And what you're hearing in a deep amplified B string is mostly 60 hz anyhow.So if you have a high pass filter properly tuned, you'll wind up using half (or less) the power as previously. Which is why I tried plugging one port to drop the cab tuning. I'm researching a very small DSP suggested by another techno-guru TB member Passinwind. It would give a variable high-pass filter as well as MANY bands of parametric eq and much more.All in a small floor pedal. With a proper high pass, I don't know of ANY cab that sounds better. What we're paid to do as bassists is to pump out quarter notes (or whatever) that have power, authority and control. In terms of function, the rest is icing on the cake. And the TC has the perfect balance of these 3.
Anyway enough of my blathering----must be the copius amount of pain meds!

Hey, all; this is is positive feedback from a KILLER bassist; check out the version of Patricia Barber doing "Ode to Billie Joe" that consists of vocal, fingersnaps and greasy, righteous upright bass that simultaneously slipslides and nails the groove.

While functioning on a far humbler level, I've had my TC112 for several months and love it. I only gig out 1-3 times a month, but with each event I more and more appreciate what this fine cabinet brings to the table. Have used it with both a GenzBenz 3.0 and a Thunderfunk 750A; good results with each, but the T-funk and T-child are truly a match made in heaven.

Wow. Compared to you guys I don't function musically at all, LOL. Hats off. That's one outstanding piece of sonic art!!!

I get that impression as well -- extra cool that he is also willing to share with us here on talkbass.
 
I had the opportunity to try out a TC12 at the NYC GTG yesterday. Unfortunately due to the rain I left my upright at home. The cab didn't suit me tonally with the electric which I didn't think it would based on spec. Hopefully I'll get another opportunity with my upright in the future.
 
I just finished recording a friend's guitar-based album using the acoustic-friendly. We ended up putting 15 or so songs to tape by pulling an all-nighter rather than the planned three days. Maybe I'll be able to do a quick and dirty mix of one song after I gain consciousness so I can share in the next day or two!
 
thudfromafar said:
What didn't suit you about it? And what head(s) did you use? just wondering

Sure.

The rig that was there had a tone hammer 500. I should have used my own head (EA doubler) but so much was going on. My rig is a Alleva LM5 with a EA NL210.

Personally I like the voicing of a traditional bass cab with over emphasized mids. It gives me the perception of additional clarity in a mix. That seemed to be missing for me. I can see how it works as a studio monitor type sound and that lack of overly pronounced mids would likely work great for DB like my VL208 cabinet. Lows were a bit flabby for my liking, although that may be more a function of the amp.

I didn't want to come in like Debbie downer or a out of nowhere negative review. I really wanted to play my DB through the cab but we had a miserable day of constant down poor and if I knew the acoustic friendly version was going to be there I would have made it happen.

I am really solidifying my own opinion that the characteristics I like in an electric bass cabinet are very different then what I look for in a DB cab and there probably isn't something out there that will satisfy me for both.

Still looking to try an AF version with my DB if there are any guys on long island with one I can try out some time.
 
Which again is the reason that I wish all bass amps had fully parametric tone controls.As I have said earlier, it's much easier to give a musical midrange boost than to tame midrange anomalies. What Duke has given us IMO is more of a neutral tonal palette with a very natural, very high end hifi sound and for me, a kickass controlled low end. I usually am eqing out lots of midrange from electric or double bass because where the midrange peaks exist in most commercial cabs give me more mid definition but also midrange wank in areas that I don't want it. I did an audiophile binaural recording for NPR with the TC (on upright)(sorry I think I mentioned this on the DB side) and in initial listening realized that I didn't need to eq out the mids that I usually do. I also usually turn the treble control (on the Doubler) down a bit. With the treble flat (something I do with EB but never upright) I found that I was getting my sound with much better definition than I'm used to All pluses and no minuses. With EB I find that I am giving a small mid boost (nice thing about the Doubler is that I can choose the mid boost frequency via channel choice). And if I want a vintagey Pbass sound, I just hit the minus 3db switch and voila! I think that we're all used to nasty midrange humps and wanky, overly sizzly treble.With the midrange humps it gives us more "cut through" but at the expense of an unnessarily aggressive midrange. I think that if we heard this type of mids on a recording that we had made we would cringe. If we reacquaint ourseves with using eq musically we can make this cab do anything we want. Now if I could only get amp manufacturers to give me fully parametric eq the possibilities are literally endless.
 
I heard the original Tc (no rear tweeter) and latest AF/Tc, both times with the Acoustic Image Clarus head. There was not an ounce of looseness anywhere throughout the range in either audition. As reported earlier, such was the AF/Tc's excellence that the owner of a highly regarded bass combo (remains nameless till he sells it) played AF/Tc for 45 minutes till he plugged in his combo only to confirm its obvious inferiority by comparison.

He already purchased his own AI Clarus and awaits his AF/Tc. He owns an estimated 7-8 electric basses, all gorgeous, all or most self-built, and two DB, one a superb Bulgarian piece. I thought I knew about gear heads till I met him.

As someone with feet in the world of music, recording, and high-end audio: big dittos all.

Surprised to read PM Eq is not relatively ubiquitous with MI amps. How many bands do you consider minimum? How many bands do you consider ideal? It's obviously much more hassle to carry a separate Eq effects cabinet.
