** This Ad is Marked as SOLD by seller and cannot be responded to. **
For selling a pair of beautifully build, hand made horn speakers. Very heavy and solid, made from mdf 25mm boards externally veneered and lacquered. The front baffle is easily removable. The speaker stands on Soundcare feet. On the top there are hand made wooden silver terminals for easy connection of optional super tweeter. The inside cabling is made with Neotech cable. The speaker drivers that are used are the famous and praised among Russian audio enthusiasts NOS Lomo 4A32 with AlNiCo magnetic system.
The T/S parameters of the Lomo 4A32 drivers are:
Fr = 46 Hz
Re = 12.5 Ohm
Qms = 1.5
Qes = 0.32
Qts = 0.26
Sd = 530 cm2
BL= 23.7 Tm
Xmax = 3 mm
Le=0.28 mH
The parameters of the construction are the following:
Height - 1000 mm
Width - 410 mm
Depth - 480 mm
Volume of the camera - Vfc = 90 ltr.
Length of the contour - l=505mm
Type of the contour - Tractrix
Area of the throat At=130cm2 (36X360mm)
Area of the mouth Am=1620mm(450X360mm)
Also there is a RLC filter that smoothens the frequency response. The filter is made with components from Jantzen. The parameters of the filter are:
R1=10 Ohm
L1=2.4 mH 1 Ohm
C1=4,7 uF
The parameters of the Speakers are:
Nominal Impedance - 16 Ohm
Rated Power - 12W
Sensitivity - 95dB/W/m
Sound Pressure - 106dB/1m
Bandwidth - 38Hz-15KHz (-6dB) and 44Hz-14kHz (-3dB)
