Features of our £2,500 or £1,800 "10
inch - High End" speakers
| 10 inch dedicated woofer
to produce the bass (e.g. bass drums)
10 inch woofers are 3 times bigger than 6.5 inch
bass/mid drive units !
|10 inch woofers are 3 times bigger than 6.5 inch bass/mid drive
when you ignore the "useless" metal frame and part of the "useless"
and calculate the AREA of the MOVING cone.
|10 inch woofers are still smaller than 22 inch Kick Bass drums,
but 10 inch woofer are 3 times more capable of reproducing Kick
than 6.5 inch bass/mid drive units !
| 4.5 inch dedicated midrange
to produce the midrange (e.g. human voices)
Our 4.5 inch midrange is a better match for the
modern 1 inch tweeter
|Modern 1 inch tweeter are marvellous, because they can go up to 20,000
(which the generally accepted limit of human hearing).
|Unfortunately, tiny 1 inch domes cannot handle bass drums,
so you to filter out the bass with a crossover at about 4,000 Hertz.
|If you have a 4,000 Hertz cross over, it mean than
half of the 4,000 Hertz goes to the tweeter,
and half of the 4,000 Hertz will go to the midrange.
|Even at 8,000 Hertz, a fair amount of 8,000 Hertz will go to the midrange.
The midrange must be able to cope with 8,000 Hertz
(even though the cross over frequency is 4,000 Hertz !)
|Some 6.5 inch bass/midrange drive units with Kevlar cones, Carbon
Fibre cones or glass fibre cones
has an uneven jagged frequency response between 4,000 to 8,000 Hertz,
caused by severe cone break-up.
|Our 4.5 inch midrange is smaller, has less cone break-up at high frequency,
and it will go smoothly up to 8,000 hertz, before falling away gracefully,
without any jagged frequency response , without any severe
|The result is very audible. You have our money back guarantee
(less £30 return carriage) of:-
|1. Greatly reduced and well controlled sibilance on female voices !
(Sibilance is when words like "his"
sound like "Hissssssk")
|2. Our midranges do not have resonance around 4,000 Hertz
to 8,000 Hertz,
so our speakers do not sound artificially
bright, and irritating !
|3. Sweet treble. Sometimes, people wrongly blame the tweeter, when
they should be blaming
the terrible frequency response of the midrange
at 4,000 Hertz to 8,000 Hertz !
|1 inch tweeter with massive
magnet to produce the treble (e.g. cymbals)
|Sophisticated cross over that
come in a non magnetic aluminium box
measuring inch x inch x inch
and weight ??kilograms !
This is about 10 time heavier
than the "typical" cross over for the "typical" speakers !
Features of our sophisticated crossover
|Most of the capacitors are BIG EXPENSIVE high voltage polypropylene
capacitors made especially for us
|Big heavy duty "Air cored" inductors for tweeters.
|"Air cored" inductors for woofers have will have a DC resistance of
almost 1 ohm,
and will affect the Q of the woofer dramatically (i.e. encourages boomy
|For our woofers, we use BIG EXPENSIVE inductors that look like small
These big inductors will NOT overload and "saturate".
These is essential for LOUD CLEAN DEEP bass and LOUD clean midrange
The low DC resistance will help to keep down the Q of the woofer, for
TIGHTER bass without boom.
|"Hose pipe" size professional tri-wiring cable.
( Flimsy silver cables are a waste of money, and affects the frequency
response badly ! )
