AudioKinesis Cabs Part VI...

#286
I got to try out Leon's TC115-8 today. What a great cab! I really think this cab could do everything I need. Now I have to start saving.

He's going to let me borrow it for a gig in the next month or so. That should really tell me if it's the one.

Duke just shipped a TC115v2 to me! I think this cab will take care of any situation I'm likely to run into.

Unfortunately the band I've been in for the last 6 years just broke up so I won't have any gig reports for a while, but the cab sure will make a great practice rig in the mean time. ;)

Thanks Duke! You're the man! :hyper:

Interesting gig last night.

I've been using a TC112AF with various active and exotic basses for the last couple of years, and loving it. Last night was my first time using my AudioKinesis/G-K "big rig" with a plain old passive P-bass.

Wow wow wow wow.

Left the amp nearly flat except for just a hint of contour, and backed off the tone control a hair. Big, cushiony old-school tone for days...

Thank you once again, Duke. You da man!

It's a Wow with active and passive.

My basses love when Fred comes over. They never sound as good as when he plays them. ;)

Steve, I know what you're saying.

After having a few practices with my latest round of gear, I've landed upon this signal chain:

Passive Lull P bass -> GK MB800 -> TC115.

For me, on a gig, it just isn't going to sound any better. On my duo gig with lots of sonic space, I may pull out the boutique bass. But the denser the mix (drums and keys), the better the passive P.

The P and GK carve out the proper sonic spot and the TC presents it straight and true.

The tone is wonderful with that cab. One thing that really sells it for me is that I stood right next to it (with my leg touching the front of it) and I could still hear myself clearly. Some of the small stages that I get to play on are so small that I am literally on top of my cab. Hearing myself is critical.

Leon, you're too kind. :)

Okay, this is just my opinion of course, but one area where I think the more traditional woofers-only bass cab has room for improvement is in dispersion. You may have all the mids you need on-axis, but off-axis they usually fall off rapidly. In fact one of the main (if not THE main) selling points of a woofer+mid cab is the wider dispersion in the midrange region. Of course a dedicated midrange driver will almost always have more top-end extension than a woofer all by itself, so that's another advantage IF you want the extra octave or so the mid adds. Not everyone does, whether their primary consideration is tone or cost.

The advantage of wider dispersion up top (another way to put it would be, more uniform dispersion, because it's already wide down low) would be, more uniform tone throughout the venue. This would let everyone throughout the venue hear pretty much the same tone, which I think is a nice thing to do.

So if I was ever going to do a woofers-only bass cab, I'd want to somehow give it wider, more uniform dispersion than you'd normally get. It has taken me a while to figure out how.

One way to get wider, more uniform dispersion from a woofers-only cab is to use a splayed array. That is, woofers either angled out, or angled in (cross-fired), which results in better dispersion up at the top end of the woofers' range. If the angle is chosed carefully, you can end up with roughly twice the pattern width that you normally would have had at the top end of the woofers' range. So in other words, two splayed 15's can approximate the pattern width (though not the top-end extension) of a single 8" driver.

The disadvantage of splayed drivers is, the resulting cab is quite wide. Well that may not always be a disadvantage, but I'm under the impression that a small footprint is generally more desirable because it's practical on a small stage.

So what I did was, come up with a way to get the pattern width advantages of a splayed array, but in a cab whose width is still live-with-able. My latest round of measurements (after a bit of fine-tuning) indicates that the Twister 215 will not only approximate the pattern width of an 8" cone up high (say between 2 and 3 kHz), but also have a generally more uniform pattern than an 8" cone. Likewise, the Twister 212 approximates the pattern width of a 6" cone up at its top end (3-4 kHz ballpark).

Twister 215: 4 ohms; dimensions 34" tall x 22" wide x 16" deep; weights and performance specs will vary according to the specific woofers used but suitable woofers include the Legend CB158; the Basslite 2515; and the Kappalite 3015 (non-LF).

So the Twister line is my attempt to build a modern radiation pattern into an otherwise more old-school cab. I'll incorporate some switchology where I think there's an opportunity to offer two useful voicings. We'll also have pluggable ports, so the very low end can be scaled back if the venue is boomy.

Any thoughts on using a pair of Faital 15PR400 in a Twister 215? Those nice sounding extended mids would seem to be ideal for this sort of build. If the size is 34"H x 22"W x 16"D what might the estimated weight be on one of these with the Faitals and something light like 12mm Okume?

Hey guys! Happy New Year. I ran across this wonderful Youtube video of our TB buddy (and my good friend of over 30 years now!) Ric Vice, playing DB through his Walter Woods/Thunderchild 112 rig (I believe he is using the new DB pickup made by Bob Heil (if I have that spelled correctly.... St. Louis based legendary audio designer).

He is playing with the wonderful Rubright brothers in this St. Louis based trio. Great playing and wonderful tone. Shows again that Duke's 'studio monitor' influenced cab line is among the best compromises in the business for getting pure, open, even, relatively flat tone in a small, gig worthy package!

I designed the Twister 215 with the Kappalite 3015 (non-LF) as one of the woofer options, rather than the inherently smoother Faital, because I can incorporate a switch to smooth out the 3015 and thus give users the ability to toggle between the two voicings.

The wood will be 1/2" (12mm) Italian poplar. I'll try to post an estimated weight in the next few days.

Thank you for the link, Ken! I bookmarked it.

It's actually a Ehrlund Pickup and Pre Amp. This is my main rig for most venues. These days, I'm actually running Ehrlund into a Headway EDB-2 pre amp, so your Walter Woods Ultra is kind of a Ultra Boutique power amp.
