To honour reaching 1K subscribers on my Youtube channel, I'm releasing the plans for Cubo Home. It's an optimisation of it's predecessor, that was designed to have the sound and low frequency response of Cubo Sub in a small format Home or Car sub. Cubo Home is great for above average levels of sub bass, with just about any sub amplifier. As a day-to-day go-to sub, whether for music, gaming, movies or to entertain a small flock of friends or family.
If you could only have one sub, build Cubo Home. If you can have three subs, build two Cubo Home and one Cubo Infra.
Just like its cousin Cubo Infra, it can be used in front-firing and down-firing mode. In a down-firing position the chamber/ cavity/ port in front of the driver reduces in-band THD, for a cleaner and deeper sounding bass, this is especially helpful with low Mms (i.e. older or PA-mid-bass) drivers.
It works with a very wide range of 12" drivers, even those that weren't designed for sub bass performance. Designed for all 12” PA mid-bass or bass drivers, to atain an usable frequency response down to 30-ish Hz*. Tested with drivers such as the 18 Sound 12W700, 12ND930, 12NLW9300, the Precision Devices 12SB30 and the Eminence Delta 12LF. Other suitable drivers that come to mind are The Box 12-280/8-A, 12-280/8-W and the Dayton Audio PA310-8. Cubo Home is also suitable for 12” home audio and many car audio drivers. It will even work with 10" drivers, especially those geared towards high excursion capabilities. If you're unsure a driver is suited, e-mail me at questionsaboutcubo@gmail.com
* To maximize low frequency performance, loosely fill the rear chamber with fibers, such as Polyfill/ Fiberfill, without blocking the airflow to the driver and port.
Size: 40 x 40 x 40 cm (Metric), 16 x 16 x 16 inch (Imperial in the making)
Frequency: From 30 Hz up to 100 Hz
Enclosure Type: Reflex/ 6th Order Series Bandpass
Metric Construction: Cut from half a sheet of 15 mm MDF (122 cm x 122 cm), no angled cuts.
Imperial Construction: Cut from half a sheet of 5/8" MDF (4' x 4'), no angled cuts.
Front-firing:
Down-firing:

Hi Maxolini,
Great to be here, I've been a member since before Cubo's were a thing. For the Cubo Infra plans on diyaudio.com click the hyperlink in the opening post 😉

Have you got:
1. Corresponding Hornresp sim?
2. Measured impedance curve?
3. Measured frequency resonse?

How big is the port ? Maybe this will work 🤷🏼

1. Created one yesterday (see also 3)
2. I get my impedance measurements from Cuboteers
3. And THD, lost in a tragic Windows 10 reboot
