Placed closely to the rear wall this sub doesn't work properly.
In contrast to some smaller dipoles this one is quite efficient due to two
large 18 inch bass drivers. The two drivers are mounted one behind the other,
called W profile (according to Linkwitz).
As described by Bernd Timmermanns, we have 3 dipole versions available - but not with Sitronik amplifier modules which are no longer available but with Detonation amplifier modules:
Using a passive dipole results in an efficiency of 88-90 dB. Explanation:
the dipole has a total efficiency of 95 dB. This value should be comparable
to the efficiency of two satellites. Two satellites in phase, however, possess
6 dB more than just one (see interview with Dr.
d'Appolito), resulting in 95 dB - 6 dB = 89 dB.
We recommend the active dipole since volume and phase are adjustable.
important hint: The measurements of AWX 184 have been changed. So don't build the cabinet according to
the old measurements.
Upon request we supply a 220 x 155 mm universal
PCB, for mounting the component.
For the passive subwoofer we recommend 2 PCB's.
