Cubo Kick is a midbass bin to enforce the Cubo series or any other sub bass cabinet in the kick bass region. Like all Cubo models, Cubo Kick is designed to offer maximum performance when used in a stand-alone operation.

Cubo Kick 15 is the largest at 62 x 62 x 62 cm (H x W x D), aimed at 80 - 200 Hz, it has the most output in the 120 Hz area, for that well known "pressure on the chest kinda feeling". Not only do the frontal dimensions match with Cubo 15, 18, 21 and Sub, but the output is also high enough to use Cubo Kick in a 1:2 ratio (1.5:1 for live music). On top of two Cubo 15's it will raise the minimal height for the high mid top to 180 - 190 cm, bringing it well above the crowd ears. The cut sheet fits from a single sheet of 122 x 244 cm, 18 mm 13-ply Baltic birch is preferred. Originally designed around the 18Sound 15ND930. Other drivers that will work:

- Eminence Kappa Pro 15
- Faital Pro 15FH520
- Faital Pro 15FH500

The width of the cabinet can easily be modified, Cubo Kick 15 at 45 cm wide is best used in combination with 12" drivers to get the middle way, 100 - 220 Hz when used stand alone.

Cubo Kick 12 is the smallest cabinet at 45 x 45 x 50 cm (H x W x D). Initial measurements show it's capable of 110 - 250 Hz stand alone, a bit below 100 Hz when stacked in multiples. With the same frontal dimensions as Cubo 12, the output is high enough to use Cubo Kick in an 1:2 ratio (1.5:1 for live music). The cut sheet fits easily from a single sheet of 122 x 244 cm, 15 mm 11-ply Baltic birch is preferred. Designed around the 18Sound 12ND830. Other drivers that will work:

- Faital Pro 12FH520
- Faital Pro 12FH500

Development:

Over 10 prototypes were built to ensure a maximum output and clarity, in a minimum sized enclosure. Cubo Kick works with a wide variety of drivers, some of which are listed above, if unsure if your driver works, send me an e-mail at questionsaboutcubo at gmail dot com. Or visit the forum: Forum Topic Cubo Kick

It's advisable to use dampening material on all the walls in the rear chamber, except the baffle and without restricting air flow to the driver and reflex ports.

Plans Cubo Kick 15:

Size: 62x62x62cm    
Frequency: 80 Hz - 200 Hz    
Enclosure Type: Port Assisted Front Loaded Horn
 
 
Cubo Kick Render 2
 
Cubo KIck Render 3
 
 
Cubo KIck 15 Cut Sheet
 

Plans Cubo Kick 12:

Size: 45x45x50cm    
Frequency: 110 Hz - 250 Hz    
Enclosure Type: Port Assisted Front Loaded Horn
 
Cubo Kick 12 Render

Plans Cubo Kick 18:

Size: 62x62x65cm    
Frequency: 75 Hz - 190 Hz    
Enclosure Type: Port Assisted Front Loaded Horn
 
Cubo Kick 18 has been designed on request and is basically a Cubo Kick 15 redesigned to suit an 18" driver, giving it the exact same outer dimensions as Cubo 18. The increased rear chamber gives it a slightly lower tuning and the slightly longer horn makes it perhaps "the most 120 Hz" design out there.

Yes, the 15nw76 has written kick all over it.

Would the 15nw76 be a suitable driver for the kick 15?

The horn bracing is spaced out at 1/3 intervals, the port bracing at 1/4. For Cubo Kick 15 and 18 those intervals equate to those measurements.

So if I understand correctly: The missing plans for the Cubo Kick 15 & 12 are the same as the ones for the Cubo Kick 18...? Just need to fill in the right sizes...?

Typical for a good 15" kick driver is an Xmax around 7 mm, at least 4 - 5 mm but as soon as Xmax gets beyond 9 mm it's a good indicator you're looking at the wrong driver.

Both the Beyma and the Oberton are high power sub bass drivers, great for Cubo 15 Extra Extended not optimal for Cubo Kick. I would look at 15" drivers with a 3" - 4" voice coil, Qts around 0.3 or lower and before mentioned Xmax figures, like the Oberton 15NXL700 or 15NMB500.

Can I make two front skids (two pieces) slightly bent like a moon or should they be completely straight as in the design?

I will have to see it to give a good answer to that.

Best regards Cubo

Hi!

Dear Cubo I have question, - very important to me.
Thank you for your time if you would like to help me.
I plan to make a Cubo Kick 15 and want to use one of those speakers Beyma 15QLEX1600Fe or OBERTON 15NXB1200 (or maybe another from OBERTON?)

Which speaker do you think will be better? I want to widen the frequency response a bit up and down.


And the secon question:

Can I make two front skids (two pieces) slightly bent like a moon or should they be completely straight as in the design?
Hope you can understand what I mean.Thank you for answering.

For live sound with a full drum set bass and keys is there an advantage between the Cubo Kick 15 vs 18? 

For most venues space is limited so likely will often be a single Kick per side used with Cubo subs.

What is a recommended XMAX for the Cubo Kick?

An increase in EBP is not necessarily good, it depends on your use, i.e. a single Cubo Kick or a stack (aim between 110 - 150 if unsure). A lower Qts x Vas product suggests better performance in a cabinet with a smaller chamber. A typical Cubo Kick driver will have a Qts x Vas product between 30 - 60.

Andrew4566 replied the topic: #24830 5 months 14 hours ago
So for a given FS the lower Qts increases EBP (good) but to get a higher Qts VAS product you must have a big VAS... at what point does the VAS get impacted negatively buy the Cubo box size?....Or am I totally in left field?

Cubo15 replied the topic: #24829 5 months 17 hours ago
Fs, Qts and Vas are the three primary parameters, so if anything you should be looking for the Qts x Vas product. Although I wouldn't worry too much as the port tuning also raises.

Cubo Kick 15 is deeper, meaning the horn is longer (and larger) thus it starts amplifying the output at a lower frequency. Typically the 15" will have more port output as well, again amplifying the lower kick.

P.S. Don't get your mm's and cm's mixed up ;)

Two related questions:

If building the Cubo Kick 15 at 45mm wide does this reduce the VAS allowable for the driver?...or is VAS not a significant parameter in this design?

Should the decision to go with the Cubo Kick 12 vs the Cubo Kick 15 at 45cm width be based solely on the need for a higher crossover to the mid/top?

Hi,

It will lower the horn tuning, giving a bit more lower kick (so that's good), the lower limit will still be 80 Hz.  In exchange it will not go as high as usual, I would cross it at maximum 180 Hz.

Hello Kick cube friend, I am new to the forum.I would like to ask you something about the Kick 15 cube.What negative effect could I have if I make the Kick 15 cube, measuring 62cm x 62cm and the depth would be 72cm.I hope your answer soon, thank you.

@Beari: It's not a typical kick driver, more a typical bass driver although it would work.

@Skyhighhifi: Cubo Kick 15 has 4 ports, for every port that you close you'll lower the tuning approximately 10 Hz but also lower output below 100 Hz. More than 50% of Cubo Kick is aimed at output between 100 and 200 Hz, so if you don't cross that high, a lot of wasted space. Cubo 15 sounds best crossed around 100 Hz but also has much more output below 100 Hz. I've seen both cabinets used for 12V PA but they will have quite distinct sounds and place different demands on the tops used above them.

Has anyone tried using a Cubo kick down to 40 Hz? Is for a 12v system so looking for something as small and lightweight as possible.

Would I be better off making a Cubo 15?

Ok :p I have 2 Cubo 15 extended loaded with kappa LF-2 and 2 cerwin-vega Prostax PS-12.. I want to upgrade this system with more kick. What should work great? Cubo 12 kick? Or anything else? And what driver? And crossover frequencies?
