Post Subject: The Scanspeak woofers.Posted by Romy the Cat on: 9/20/2017
I would not advise to use my
Scanspeak woofers all the way to 150Hz. For sure you can but I feel that
they are fine in sub 100Hz. The upper bass need to have more HF resonance and
the Scanspeak rubber surround is not best for it. For sure it is not regular
rubber as it use in PA woofers. It is a very good non-inertia rubber that
rather feels as fabric then rubber. Nevertheless it is not paper, fabric or leather
and I would not climb very far in HF with those driver drivers. For sure you
will have sonic output in there but you will also find many other drivers that
would perform belter then the Scanspeak over 100Hz.
Your diagram of the SPL change
with different type of damping is very interesting, thank you for
sharing. It is also very much what I suspected. I care less what is going on
over 30Hz but the left side of the diagram is very nice indeed.
Anthony, one more very important tip I would like to give to
you. Churchill (is I am not mistaken) once said that if you want to confuse
people then give them facts. The point was that facts do not clear anything,
the important are not the facts themselves but the patterns of the facts and
the interpretation of the facts meaning. It took for mean a few years to understand
how to measure loudspeakers. You need to measure them AND to listen them. If
you have any minute mis-synchronization of auditable and measurable then you do
not measure the right things. It is not always so simple, in fact it might be
very complex and at time you will be find yourself that what you feel conflict
with what you objectively witness. It sometimes
take a long thinking on the problem and many experiment but you MUST find a
harmony between what you hear and what you understand as a measurements. If you
do then you will perceive measurements very differently, I promise you. The measurements
will be not an indicator of you playback response but a reflection of your experience
and it will be a very different category.Rerurn to Romy the Cat's Site
