Introduction
For demonstrating and general use I have been working on my Zeus-Athene
Series speakers.
These use more accessible construction and shapes and are
intended primarily as demonstrators for the Zeus Amplifiers (small
and light enough to be carried up and down stairs and to fit in the
back of a small car).
The first version is based on a pair of existing ported cabinets
that I worked on in 2002 which are fitted with new drivers and
crossovers. This speaker has a pair of
E.J. Jordan
JX92s main drivers plus a Vifa 1" soft dome tweeter
(TC26SF05-06).
Crossover is a 12dB LP / 18dB HP set at 3.0 kHz. This gives an impedance
wobble at the crossover point and I intend to add a LCR to even this out so the
amplifier will see a constant impedance across this point.
Bass -3dB response is down in the 50-60 Hz region.
Further Development
Use a pair of JXr6HDs for the main audio band positioned side by side (not
vertically), with the pair of
JX92s main
drivers for the bass only.
The crossover will be 6dB LP and 6 dB HP around 200 Hz. An additional
mechanical HP filter of 6dB for the JXr6HSs will be effected by selecting the
volume of their sub-enclosure.
(Further details to be added.) |
