fullrange double horn

hm · 26th June 2010, 10:06 PM

Hello,
i made a new construction

simpler as an SAXOPHONE
and less wood than an RDH20

opinions?

Hi,

are both horns with their drivers optimized to balance their
impedances in a way to be a more resistive load than a single
one would be ?

An impedance plot of either of the single drivers and both connected
in parallel would be interesting to see in how far the motional
parts of the driver impedances are balancing.

The folding looks nice indeed.

Kind Regards

Hello,
yes,
look my KORNETT real
measurements and simulations:
kornettmess

all double horns look nearly the same.

I see,

nice work !

Where is the damping applied ?

Hello,
soft fiber is the key material,

more info:
FDBH20

Hi,

no fibers in the "air path" or the compression chambers,
just soft walls ?

Kind Regards

Hi,
polyester Watte around the driver,
not in the horn throat,
the softfiber reduce inner reflections
over 100 Hz.

Very interesting concept. What do you think about
sheep wool instead of polyester ?

I had good results in conventional speakers with
sheep wool near the driver.

Thank You very much for explaining.

Good luck !
