CIONKEN

It is offered to your attention Acoustic System (AS) "CIONKEN" design JENSEN-ONKEN on loudspeakers CIARE professionals series.

In the AS insert loudspeakers: on LF PW251, on HF PT382.
the AS has the following Parameters:
a range of frequencies: 36Hz (-10dB), 48Hz (0Дб).... 20KHz (0Дб), 22KHz (-3dB).
(in LF-area parameters settlement).
If the mode, when pressure hardly less, and LF is required - More low, it is possible to put simply pair of books
in the central tunnels (reduces on 5Hz a minimum)
Passport sound pressure of LF loudspeaker of 97 dB/1W
the Sizes (width x height x depth in centimeters) 61.2 x 95,2 (c HF) x 35
Weight of 30 Kg

АЧХ (in a living room) more or less authentically it was possible to remove Only about 500 Hz (red - a phase):

the Sizes of boards and реек for one AS:
a lobby (1шт): 520мм x 750мм
top (bottom) (2шт): 612мм x 350мм
tunnels (2шт): 271мм x 750мм
back (1шт): 580мм x 750мм
рейки basic (4шт): 30мм x 30мм x 287мм.
screws-samorezov long 31мм - more 200шт
HF section: 170мм x 300мм (a hole in diameter 120мм hardly above The center) and the bottom shelf 240мм x 200мм,
from above and filters are closed by half of a plastic bucket, обклееного self-sticky under color
cases.

the Front view:

the Side view:

LF and HF sections are completely independent, in LF there is a coil, in HF - filter high lloudspeaker
LF loudspeaker it is finished: c an inside suspend diffuser: with By solvent "646" (russian, aceton + ceton) it is removed partially filled in between folds Impregnation in such a manner that resonant frequency as a result would turn out Dynamics 45Гц.
It is necessary to wait days (approximately so much impregnation is restored) and To check up result.
As a result are received such T/S data:
Fs = 45 Hz
Re = 6.2 Ohms
Qms = 2.1
Qes = 0.41
Qts = 0.343
Mms/d = 31.8 gr
Sd = 3.730E-02 m^2
Vas = 76,6 l

Crossover:

On frequency of section from 2.5 KHz to 4 KHz both dynamics work Simultaneously, but falling down (LF) and accruing (HF) cross on level so, What in Result the total level is not enough variable (it is connected with smooth recession LF dynamics above 2.5 КГц and undesirability of work with full level on Frequencies more low 3 КГц at HF dynamics.
As a result equal sounding in "a problem zone" as has turned out at Measurement, and listening of a various material.

For manufacturing the AS are used laminated boards from MDF 16мм, as the most widespread material.
the Forward wall is strengthened in the bottom part around, cut out of this Panels (a hole under динамик, it is necessary and to cut at once a carving under screws Fastenings of LF dynamics), the back wall is strengthened vertically fastened To it рейками. And Internal walls are covered warmed линолиумом (except tunnels and Input in them), линолиумом to boards.
Between a forward and back wall установленна a rejka-coupler.
in side connections are executed with use реек section 20х20мм from Firm breeds of a tree.
To collect better in a following order:
In the beginning to collect from external boards a frame, then to fasten рейки for installation of a back wall (on all длинну lateral walls, and Width of top-bottom, on distance 16мм from edge of the back party the AS.
After to lateral walls from within to fasten bruski-support screws.
to Attach to the vertical party (one) each boards-walls Tunnel рейку, it is equal on board edge, and on short рейке not top and a bottom This board (what to top and and a box bottom зафисирывать it).
Further to брускам (as from within) the internal are fastened Boards (tunnel wall), maintaining distance from their edge to переда 16мм to fasten narrow edges to top and a box bottom, then to fasten рейки on top and a box bottom, as on distance 16мм from Forward part the AS.
Now it is possible to establish the forward panel (to watch what villages Exactly) and to fasten from within to рейкам below, above and рейкам on walls Tunnels.
All joints a rejka-board at first to spill glue ПВА (it is convenient in Tubes), after drying they be to miss the mark places where it is possible Small изгиб - plasticine, or other elastic hermetic.
While glue dries - in a back wall we drill holes, on distance 10мм from edge, with step ~63мм at lateral edges,
And 57мм - the top-bottom, under screws-samorezy, all turns out 11 on everyone To vertical edge and on 9 on a bottom and top
It is possible now оббить (glue and carnations) линолиумом internal Walls (and back) to establish on the forward panel a rejku-coupler (it is long It 316мм), and LF динамик.
On the back party of all реек to which will be pressing back The board to apply a thin film plasticine, or other non-drying hermetic
Now to solder a wire to dynamics, mounting it to to To rejke-extension and to solder to the terminal that is established on a back wall.
we Put a back wall into place and at first on corners, then on To circle, we press it to рейкам screws-samorezami
HF the section is simple also special attention does not demand, The basic cable - under закрутку
is connected to the terminal by "bananas", and

Listening:
The Sound rather strong, beag'gest, very much differs from sounding "standart - house" the AS.
Well various music on style - Malinin, Pink Floyd, Black Sabbath, Oscar Benton, Simon and Garfunkel, etc.
