Cubo 18

defo a winner for your musical styles.....

can i use the ciare 18.00 on these box?

Yes, that driver can be used, it's definately not the most efficent driver out there but that Xmax makes it everything but a budgetary driver.

My educated guess is that it works best in Cubo 18 Extended, but Í'll be able to tell you for sure this Sunday.

how about the ciare NDC 18-4 S is it still suitable on the cubo 18?

how about the beyma 18p1000fe will they play well on the cubo?

It's still Sunday right?

The 18.00 works best in Cubo Extended.

Must say, I personally would prefer the Ciare NDC 18-4 S over the 18.00, and on it's turn prefer the Beyma 18p1000fe over the NDC 18-4 S. In order they rely more on efficiency instead of (though) impressive Xmax capability, meaning you need less power for a certain SPL.

thanks for the reply sir, a big help for me. now i will have to build 8pcs. of those cubo 18 to be put in astovan. it's for car application sir. on what box does the ciare fit ? does that mean beyma is better than ciare?

The Ciare 18.00 has small Vas and high Qts, suggesting it likes small chamber volumes but wasn't designed to drive horns. Basically sounds as a good driver for car-audio to me, better then most PA-drivers for that application
(small reflex, closed box or perhaps even open baffle as long as you keep close check on the excursion). Cubo 18 however is aimed at PA. All brands have better and lesser drivers (up to the point that you're scratching your head and asking why?!). I would rate both Beyma and Ciare as good brands.

Do any true half space measurements exist for any of the cubo designs yet?

I'm also curious about max continuous SPL from the cubo 15 / 18 ?

I'm currently looking into a ~140L net 40Hz PD186 1x18 reflex cab project. The winISD simulations are giving me an f3 of ~42Hz which I assume is close to that of the Cubos? I'd be using it for live bands (nothing bass heavy as dance) so thats as far as i need it to go down. I'm trying to decide if the larger cab size of the cubo is worth it?

Also is it possible to modify the Cubo designs to get closer to a width of 580mm. Its a nice width for packing vans

Thanks

Not that I’m aware of. It isn’t very high on my agenda. To be honest I don’t see the advantage.

That depends on the specific 15” or 18” used. Typically in the 130 dB/ 1m region (add 10*log(power) to the sensitivity 101 – 102 db/w/m).

I'm trying to decide if the larger cab size of the cubo is worth it?

The increase in cabinet size will add 3 – 5 dB to the SPL.

Also is it possible to modify the Cubo designs to get closer to a width of 580mm

Not a problem. Every inch decrease in width will increase Fc-low about 1 Hz.
