W frame sub
FR_di_sub - Frequency response at the listening position with low frequency boosting using the Reckhorn B1 (http: /www.reckhorn.com/index.php?ln=en&prod=b 1) and low pass filtering using the sub output of a Sharp home theater receiver.
impedance - Impedance of the dipole sub. FS is 26-27 Hz. FS of driver alone: 34 Hz. Strong resonance around 200 Hz.
Water fall plot mesasured at listening position. - No boost or filtering applied. The slot of the W frame woofer faced the mic.
Frequency response at the listening position - The black line shows the FR at the listening position when the slot of the W frame is directed towards the microphone. The blue line shows the FR when the sub is rotate 180 deg, the larger openings are facing the microphone, the slot is facing the back wall. No LF boost , no EQ and no filtering performed.
FR 10-500 with-phase
The sub is placed just behind the listening position, at ear level. - The red part is a blanket that covers the sofa. I temporally placed two pieces of rockwool between the sub and the back of the sofa in order to decrease reflections from the hard surfaces.
SIde view. Foam helps to decrease the 200Hz resonance
View from top. The top of the sub has been removed for the picture.

Impedance plot measured on a single woofer (both woofers are mounted)
Dimensions in millimeters. MDF thickness is 18 mm.
