|Summary||The EKA is a 2 way bass reflex in 15 L box.
Frequency response is 39Hz to 24KHz.
Sensitivity: 90db 1W/1M
The tweeter is the SB Acoustics SB26STC-C000-4.
The woofer is the SB Acoustics SB17NRXC35-4.
The low pass network is a 3rd order design.
The high pass network employs a conventional 3nd order filter
The X-over frequency is 2.4KHzIn Indonesian Eka means the first child. Representing the first kit of this very new company. a simple design, easily modified to your personal likeingBass reflex speaker designed for off-axis listening (i.e. not to be toed in – certainly not more than 10 degrees). This was done to create a larger uniform listening area and to make the cross-over network simpler. Bass reflex was chosen to minimize cone movement in the resonant frequency area (though cone movement will be larger at very low frequencies). It also makes the design more versatile – should anyone prefer a closed box, it is easy to seal the port tube. The use of bi-wiring terminals makes it possible to use an external cross-over, which makes cross-over experiments much easier. The tweeter is offset to reduce diffration problems. Internal bracing is used to reduce cabinet wall vibrations. It is recommended to place this speaker on a stand not too close to the rear wall. The distance from the floor to the centre of the tweeter should be about three feet. Possible modifications: Cross-over, damping material, and port tuning. It is recommended to place this speaker on a stand not too close to the rear wall.
