From a basreflex perspective: The magnet inside the chamber means the chamber is smaller, whcih means a higher tuning. The port on average has a larger surface area and thus a higher tuning.
Hi Cubo, is there much difference in SPL with the MAGNET inside the chamber as opposed to outside? I think you have mentioned that the SPL increased with the Magnet Out?
If you mean lower frequencies in stead of higher frequencies you're correct. Cubo Sub has equal sensitivty (on average) in comparison with Cubo 15. The Fc is lowered up to 8 - 10 Hz compared to Cubo 15. Excursion is increased on average, to keep the volume of the cabinet to a minimum. Therefore 15" would work but as a rule of thumb an 18" would handle more power mechanically.
I am guessing that if the cabinet was bigger then the cab could play higher freq's but the output would be lower?
There is a very big chance that it will, however: It has many different T/S-parameter sheets floating on the web, some with inconsistant parameters. So it's very hard to do a simulation on it. Luckily Cubo 18 will work with a wide variéty of drivers (from V18-1000 through the 18LW1400 upwards the infamous 18" Kilomax). So there is a goof chance it will do just fine.
Hi Cubo, what about using p-audio c18-650el.will it work?
This is my first post here.I have 4 of this in an old keele's W-bin,can i use this in the CUBO 18?Thanks you!
