You should also know that the full-range driver is in fact a myth. They
are all dual cone devices with some sort of mechanical crossover

Hi Don - yes, the majority are as above, but I'm talking single cone
here.


I would also disagree with Don's statement, especially if you take the
umpteen million single cone/FR drivers that are used worldwide in radios,
TVs, cars &c. - I certainly have single cone Visaton drivers on the go here
myself...


As you can see, you can just about coax enough bass from these
aluminium units and the highs are there. The Monacor isn't as peaky as
the fr suggests. I have a friend with the Jordans and in my opinion
they sound better with no tweeter. He's endlessly working on the
crossover - I think it's better without. Maybe it's a cop-out to not
use a crossover, but crossovers do alter the sound, and I'm not sure
it's worth it in the end.



Hah!

It never fails to amaze me that, given the extremely low rate of traffic
here, just how *topical* the group continually manages to be! Only yesterday
I finally consigned my Jerichos to the garage for all eternity* having
decided that they will never be any good without correction networks to
contain the peakiness that has remained constant with summat like 4
different drivers being tried!

I found these pages to be very informative:

but still don't understand the technology/science well enough to consider
efforts made *trying* various networks to be likely worth the
risk/time/energy/expense - too much likelihood of a 'near miss' and endless,
ongoing experimentation...!! (As your friend seems to be discovering!)

In any case, at best, I see multiway speakers with complicated crossovers
(19 elements in the B&W TLs I had and a crossover bigger than many amps in
the Rogers Studio Monitors I had) as a costly fudge to allow the use of
drivers that will provide unnecessary frequency extremes at the cost of
immediacy, speed, timbre and clarity - see:

for mention of a good example of a popular speaker (or type of speaker) that
is liked and used by many, despite not appearing to 'have it on paper'...??

As I do from time to time, I did a 'back to basics' SS amp/CD/2-way speaker
(Ruarks) comparison the other day and was quite surprised just how muddy and
blurry the sound was compared to my Lowthers - I had forgotten that the
setup that works brilliantly for TV/Movies (on a daily basis) is quite
useless for music! (So *boring* after the FR units.....!!??)


*Unless anybody wants to take them on a swap 'em for summat interesting...??

See the details he

- but expect the wording to be changed in the near future and don't
underestimate the size/weight of them!
