Cubo 18

Whether you use the driver with the magnet inside the horn, or with the magnet inside the chamber, I like to leave up to you. However for this particular driver I would recommend Cubo 18 Extended with the magnet inside the horn (due to the largish Vas with medium Qts, which also makes it quite efficient btw).

Best regards

Mr. Cubo

i want to get all of the cubo plans 12,15, and 18
standard and extended version

For now i think i i will start with a cubo18 standard or extended, depending on the driver
and on the budget of course , that is not big btw
Thanks
Max.

cubo 15,18 and cubo sub are all posted in the "plans" section in the top row. I believe the plans also show the modification for the extended version.

but cubo12 dont i dont know why and also cant find the extended versions only the standard
and there is no list of all suitable drivers , only 2 or 3
it would be nice to have a list of drivers that you can use with the cubos, at least the top 10 for each design

the extended version is on the 18 plans. It is exactly the same except for one additional internal panel. As for the 12 -> hornplans.free.fr/cubo12.html

Mr. Cubo might help with some driver suggestions, but I have never seen a top ten list. He does list recommended parameters for T/S though, so you should be able to find something rather easily.

hi cubo can you tell me the best setup for a cubo 18 loaded with kilomax pro 18 and how will it perform with this diver
thanks

Hi Cubo,
I'm getting ready to build a Cubo 18 that will be used along with a mid/high pack only as a drum monitor. This driver I feel specs out pretty good. Correct me if I'm wrong. Dayton Audio PA460-8 18". I don't need tons of power and the price is right. I hope to build it only 560mm wide. Simply to match the width of the mid/high pack. Also I'm curious if I should build the extended version with this driver.
Thanks for your time.

@Ginge and Spoonman: Both drivers fall into the same category (Fs - Qts - Vas - relation) wise (though the Kilomax has a higher power handling). Both are best suited for Cubo 18 Standard.

The high Qts and Vas means they'll like (very) large reflex cabinets. If you like a compact cabinet Cubo 18 is a good choice. You will drive up the lower frequency limit (excursion and output) by ~1 Hz for every inch decrease in width.

@Maxolini: I wish it was that easy. Large budget, small budget, ferrite, neo, brute force, small gathering. Location is a strong one, living in Europe means a difference in availabilty and price between North, South, East and West. Same goes for the other continents. Sometimes I get inquires from Africa or Asia, only a slight idea what brands and quality they have over there.
That's ten different drivers already or 10 Top 10's. Basically a bunch of contradicting T/S-parameters and then there's stuff beyond T/S-parameters.

While it's rather easy from my perspective, oh wait, no that's a lie. Well, for now let's keep it as it is and hope people get encouraged to learn a thing or two about T/S-parameters

Best regards

Xmax(mm) - 6
Mms (gr) - 165.8
Bl(N/A) - 19.9
Le@1Khz (mH) - 1.34
Cms(mm/N) - 0.11
Rms - 14.1

Impedance - 8 ohms

Thank You !

Hello Guys

Me and my friend is currently building 4 x Cubo 18 ext. mountet with RCF L18P300.
Tonight we finished the first one and tested it. We are impressed!
The fast and hard kick from cubo 18 combines wery vell with our 2x12" / 1x2" / 2x bullet top speaker.

Now we are looking forward to building them completely finished to hear them all play.

We use old-fashioned fabric and aluminum trim instead of paint. (see profile picture)
(Have tried to upload pictures but can not get it to work).

Thanks to Mr. Cubo for the speakerplan!
