Cubo Infra: Also known as Cubo HT is a true subwoofer for Home Theater and low bass songs (https://www.youtube.com/
Development: Cubo Infra is the 3th prototype in a line of hybrids aiming at low frequency reproduction down into the infra region. Made from 1 and a ¼ sheet of 18 mm MDF, it features a double baffle and an inner port wall that effectively acts as bracing.
An Imperial version is in the making, plans available on request.
Front or down-firing: Its design allows it to be placed with the driver aimed towards its audience or, with rubber feet of 2 cm (4/5”) height, in a down-firing position. This maximizes the front chamber volume, creating an acoustical low pass filter that makes it sound like it drops even lower, it can also mask mechanical driver noises.
The measurements below show the response in a corner*, in down-firing position, with a 24 dB/ octave Linkwitz-Riley low pass at 60 Hz or 80 Hz without a high pass. Based on hearing alone the response drops off quickly below 17 Hz.
* One thick stone wall, one thin stone wall and a wooden floor
