bass double horn
Hello,
i made a new construction
~34 Hz
for 3", 5", 6,5" and 8"
bass and fullrange driver,
15 cm flat behind the flat screen
or two with 100x120x15 cm,
or sideboard for
sat placement.
the 17 inside width
would be a best solution with the
TB W6-1916 and a FE166 EN
or TB W6-1559S on top.
the 23 cm inside width
would be useful
for div. 8" and bass
like the Monacor SPH210
with superb
sytem impedance,
opinions?

Re: bass double horn
That's cool. At first i thought they shared the same opening but on closer inspection i see they do not. I wonder how things would change if each driver shared the same opening?

Hi Godzilla,

The two drivers drive two different horns, of different length and expansion.
The idea is that the horns have different peaks and dips and fill in each other's weak points
or at "about what" you can read the effect:

Horst,
" unfortunately only approx. 2 out of 10 CD's contain high quality recordings "
Make that "0.2 out of 10." And my neighbours teenached children buy all the rest and play them all day long.

Re: bass double horn
If two different horns cancel out their weak points, why not have one driver and two horns? Then you don't get the problems associated with running two drivers. After all, isn't a Karlson meant to model an infinite number of horns of different lengths (or something like that)?
Or have I missed a really obvious point?

Re: bass double horn
Felix,
this you won´t get with one driver in two horn,
the sum real measurement is:
also translate this phenomenon to the membran movement,
look the step response of the SAXOPHON, it is better as can be ,-))
look in the middle an read:
http://www.hm-moreart.de/11.htm
What difference can membrane movement interlacing
and bass horn mouth distance make?
An extension of the low-transmission area by at least one octave, reducing
the housing volume by up to 50%, in comparison to a single driver solution.
Indirectly right / left radiation and bass horn mouth distance prevents sound
pressure increase over 100 Hz, reduction and linearization of membrane stroke
gives a very fast, tight, contoured and clean bass response, with outstanding
properties.
Through membrane movement interlacing there are more bass, due to the bass
horn mouth distance, there's no rise above 100 Hz. So the pressure chamber can
be kept extremely small, both horns are extremely small. Small is also the air mass
in the horn and the wall-to-wall distance inside the horn is short, the relatively
small cabinets also contributes to the fast, contoured bass reproduction.
if you don´t think so built your idea an show us with measurements.
