BEWARE OF FAKES - There are con man claiming to sell
our MODIFIED IN ENGLAND BY US amplifier and speakers.
The fakes are the original Chinese version NOT modified in England by us.
We will match the price of fakes, but we will give you the Chinese version
that has NOT been modified by us.


I apologise that for our £650 price
because we have spent a lot of time
MODIFYING THESE SPEAKERS IN ENGLAND
after
modifying, measuring the frequency response and impedance curve, listening,
modifying, measuring the frequency response and impedance curve, listening,
.again, and again, and again, and again
modifying, measuring the frequency response and impedance curve, listening,
modifying, measuring the frequency response and impedance curve, listening.
Some people think that our product sound good, by pure chance and luck.
Our product sound good, because it is developed with
a lot of listening + measurement
+ HUGE amount of technical knowledge and practical experience
accumulated over 30 years.

 

 

The price includes
a small black cloth grill,
in the shape of a figure of 8,
that is about 9 inch tall
and about 7 inch wide.

The secret of these speakers is the EXCELLENT POWERFUL BASS, DEEP CLEAN bass,
produced by a 10 inch woofer (better than subwoofer) hidden on the side of the cabinet.

10 inch woofers are 3 times bigger than 6 inch speakers (when you calculate the moving area,
without the 'useless' metal fram and part of the 'useless' cone surround.


 
The original Chinese version of these speakers were excellent, except that
1. Some British Hi Fi enthusiast might complain of too much boomy bass,
    so we 'tuned' the speakers to get less bass, but deeper bass,
    and 100% boom free bass.
2. I felt that it could not play insanely loud,
    before some of the midrange crept into the tweeter
    and overload the tweeter.
    We have solved this problem with a
    "British Notch Filter tuned to the fundamental resonance frequency of the tweeter".
     The treble can now go insanely loud, WITHOUT getting harsh
Unfortunately the modified version is much more expensive than the original version,
but it is still a GBP £650 bargain with money back guarantee (less £60 or £30, within 30 days)
that they will easily beat British GBP £1000 to GBP £13000 speakers.
Sceptical ? Please read on ..........
LOUD , DEEP BASS that is 100% boom free
We have tuned the bass cabinet for deeper bass,
and added the CORRECT AMOUNT of sound absorbent
to produce what I hope to be the correct bass
for the 'typical' British Hi Fi Enthusiast.
This is why 1 month home trail in your living room is so important.
A demonstration in the hilariously small 10 feet listening room,
where you are forced to sit 5 feet from the speakers,
is a total waste of time,
if you have a 20 feet living room at home.
There is less bass,
but the bass becomes deeper and much better controlled
and is 100% boom free.
This speaker does NOT "invent" bass (when there is no bass)
like some British GBP £600 to GBP £2000 speakers with 2 pieces of 6 inch woofers,
or Hi Fi magazine hype of GBP £1400 to GBP £7500 inadequately stuffed transmission lines,
or bass heavy and boomy GBP £8000 15 inch woofers.
GUARANTEED ABSOLUTELY 100% NOT IRRITATING BASS,
AND YOU CAN LISTEN FOR 10 HOURS STRETCHES,
AND YOU STILL WANT MORE !

 
 
 
LOUD treble, that does not become harsh,
( until it is at a deafening level )
We add a
"British Notch Filter tuned to the fundamental resonance frequency of the tweeter",
so the tweeter can go MUCH MUCH louder (without becoming harsh)
The British Notch Filter also has a secondary benefit
in removing the SLIGHT brightness in the upper midrange / lower treble
ABSOLUTELY 100% NOT IRRITATING TREBLE,
AND YOU CAN LISTEN FOR 10 HOURS STRETCHES,
AND YOU STILL WANT MORE !

 
 
Trick you into believing that
your favorite singer in your living room
(when using any half decent recording + one of our valve amplifier, from £250 to £1400)
Adjust the volume to a realistic life size human voice,
close your eyes (you hear 5 times better with your eyes closed)
and your favourite singer is in your living room
(when using any half decent recording + one of our valve amplifier, from £250 to £1400)
OR YOUR MONEY REFUNDED (less shipping cost, within 30 days)
No, we cannot take the credit for this excellent midrange speaker.
The credit belongs to the Chinese designer (living in China)
and the Chinese workers who works very hard..

 
 
MONEY BACK GUARANTEE (less GBP £ 30 or GBP £ 60 , within 30 days)
if you disagree with any of the following
1. excellent quality of sound, with a money back guarantee that
    it will VERY EASILY beat GBP £1000 to GBP £4000 Western speakers.
    + EXCELLENT MIDRANGE THAT DOES 10 TIMES BETTER JOB OF
     TRICKING YOU THAT YOUR FAVOURITE SINGER IS IN YOUR LIVING ROOM.
2. 100 times better bass than 6 inch bookshelf speakers
 
There is a 10 inch woofer mounted on the side of the cabinet.
10 inch woofer are 3 times bigger than 6 inch speakers,
when you calculate the moving area,
without the 'useless' metal fram and part of the 'useless' cone surround.
Cabinet tuned in England for a bit less, but deeper bass that is 100% boom free.

 

3. 10 times better bass than floorstanding speakers with one or two pieces of 6 speakers
            (including GBP £1400 shortish transmission hyped up in Hi Fi Magazine, with boomy bass)
4.. 10 times better bass than our competitors subwoofer in smallish cabinets
HUGE amount of distortion
in competitors subwoofers in smallish cabinets.
Shove 12 inch subwoofer into SMALLish cabinet,
and FORCE IT to operated below the system resonance frequency,
and you get HUGE amount of bass doubling (2nd harmonic distortion)
and HUGE amount of 3rd harmonic distortion and HUGE amount of ...... . 
Please ignore the smokescreen that the built in amplifier has 0.001% distortion.
5. Human voices is 10 times more natural and realistic than
    6 inch bookshelf speakers with modern 'High Tech' materials.
Please ignore the silly adverts that
our competitors speaker uses carbon fibre and aluminium, like racing cars,
unless you want your loudspeakers to sound as noisy as a racing car.
Please ignore the silly adverts that
our competitors speakers uses Kevlar, like bullet proof vest,
unless you intend to use your speaker for target practice.
Engineers use steel reinforced concrete
to build the tallest, most prestigious  'sky scrapers' buildings,
but nobody is going to use steel reinforced concrete to make loudspeaker cones !
Please could somebody give me a good reason,
why materials that are good for racing car, bullet proof vests and tallest skyscraper,
are also good for speaker cones ?
      We use VERY sophisticated coated paper midrange
      PROBABLY THE BEST MATERIAL FOR SPEAKER CONES
       with about the best rigidity for it's weight
      + very high mechanical loss to control cone break up
      + coating to dampen and strengthen the cone with minimal weight disadvantage
      + rubbery cone surround to absorb cone break up
      + different material for dust cap
      According to my "Golden Ears",
      WELL DESIGNED (that need not be expensive) coated paper cones produces
      the MOST NATURAL, REALISTIC BELIEVABLE human voices,
      even more than our Ultra High End exotic 3.5 inch Beryllium metal domes midranges
      in our Yamaha NS-1000M.
       This sound unbelievable until I explains that you have to crossover 3.5 inch dome midrange
       or 3 inch soft domes in studio monitors at quite a high frequency,
       so half the human voices comes our of the dome midrange,
       and half the human voices comes out of the 12 inch woofer.
       12 inch woofer are NOT very good at producing the ULTIMATE quality midrange.
       And if the human voices comes out of 2 different speakers,
       there will be problems with phase response, drive unit matching, etc. at the crossover point.
6. Midrange is 100 times better than 6 inch '2 way' or '2.5 way' speaker
    when there is a human voices AND A BASS DRUM AT THE SAME TIME.
Overloading problems with '2 way' or '2.5 way' speakers
HUGE 22 inch kick bass drums or HUGE 32 inch kettle drums
will EASILY overload SMALL 6 inch speakers.
Once 6 inch speakers are overloaded,
they produce MANY MANY PERCENT of distortion, and human voices
will sound blur / muddled / congested (like somebody with a blocked up nose).

 
How do our '3 way' speakers solve this overloading problem.
Most of the power from
HUGE 22 inch kick bass drums or HUGE 32 inch kettle drums
is diverted to the 10 inch woofer (better than most subwoofer.)
So, our 6 inch DEDICATED midrange seldom overload,
unless you are playing music at ear damaging levels.
No, it is not a new innovation. For the last 40 years,
many of the seriously ultra high end expensive speakers are '3 way' speakers like
our Yamaha NS-1000M 12 inch woofer + 3.5 inch Beryllium dome midrange + 1 inch exotic beryllium tweeter
our Kef OLD Concerto 13 inch x 9 inch woofer + 5 inch midrange + dome tweeter
Acoustic Research OLD AR3a  12 inch woofer + dome midrange + dome tweeter
Celestion Ditton 66 12 inch woofer + 12 inch passive radiator + dome midrange + dome tweeter
JBL Century L100 12 inch woofer + midrange + tweeter.
You might not have hear of them, because they were so expensive, that few people could afford them..
The modern '2 way' speakers with 6 inch or 8 inch speakers,
were designed for Hi Fi Enthusiast on a budget.
For some strange reason, some Hi Fi magazines have hyped up
these small '2 way' speakers as the 'bees knee'.
It would be nice if Hi Fi magazines could tell their declining number of readers
that small 6 inch speakers are NOT really suitable for 20 feet rooms, and it
is extremely difficult to 'seamlessly marry' subwoofers to the main speakers.
7. LOUD treble is 10 sweeter than most GBP £300 to GBP £1000000 speakers.
    Our treble does NOT get harsh (overloads) as easily as  most GBP £300 to GBP £1000000 speakers.
    We put in a notch filter at the fundamental resonance frequency of the tweeter,
     which helps the crossover to prevent more of the midrange from reaching the tweeter,
     and overloading the tweeter, so.....
     Our treble does NOT get harsh, even when playing MUCH MUCH LOUDER
     than most GBP £300 to GBP £1000000 speakers,
     because most speaker designers do NOT use notch filters, to increase power handling.
Unfortunately, Western Loudspeaker Industry (and Western knowledge on Loudspeaker design)
has been in decline for 30 years.
30 year ago, Kef and Celestion (when they were British company, and not owned by a Hong Kong company)
would use complicated sophisticated 18 db per octave crossover to keep the midrange out of the tweeter.
(Small amount of midrange will EASILY overload the TINY 1 inch tweeter.)
I (and the Audio Engineers from 30 years ago) am shocked that
one range of famous British speakers selling for £1600 to £13000
proudly boast that it uses a simple 1 capacitor , 6 db per octave crossover for the tweeter.
Simple 1 capacitor , 6 db per octave crossover for the tweeter can cause problems.
If you believe the nonsense that
1 capacitor , 6 db per octave crossover is better,
please buy our £50 speakers.
Most of our loudspeakers (expect for our cheapest £50 speakers) will use
more sophisticated 12 dB per octave crossover for tweeter,
(to keep more of the midrange out of the tweeter)
(to prevent the midrange overloading the tiny 1 inch tweeter)
Some of our MODIFIED IN ENGLAND speakers adds on a
"British notch filter tuned to the fundamental resonance frequency of the tweeter"
(to keep more of the midrange out of the tweeter)
(to prevent the midrange overloading the tiny 1 inch tweeter)

 
( If I do not listen to the speakers, I cannot tell you how good or bad they sound like. )
(      This speaker were new, until I needed to write a review for our eBay listing.        )
POWERFUL pair of MODIFIED IN ENGLAND speakers
with 10 inch woofer mounted on the side of the cabinet
+ 6 inch mid range
+ 1 inch tweeter
        AND
NEW good quality 'fashionable' speaker cable with transparent insulation
        AND
NEW Mr Bob Marley Reggae CD to prove that these speakers have 100 times better bass than speakers with 1 or 2 pieces of 6 inch speaker (regardless of £300 , £1600 or £4000 price or hype in Hi Fi magazines or internet forums, by dealers pretending to be innocent members of the public.)
I challenge our competitors to supply Mr Bob Marley Reggae CD to prove that
our competitors SMALL 6 inch speakers got powerful, well controlled bass.
Powerful Deep Bass
We have tuned the cabinet to a lower frequency
and carefully modified it
to produce POWERFUL DEEP BASS that is 100% BOOM FREE. 
100 times less irritating then some GBP £2000 speakers with two pieces of 6 inch speakers
that booms and booms and invent bass (when there is no bass).
100 times less irritating then GBP £1400 speakers
with a short transmission line (less than 14 feet long)
and insufficient sound absorbent to produce huge amount of boomy bass
to impress Hi-Fi reviewers.
Sweet Treble, that can go LOUD, without becoming harsh
The "High Tech" tweeter uses a transparent dome + British notch filter + British Zobel network
and is VERY NEUTRAL,
produces SWEET TREBLE, WITHOUT DRAWING ATTENTION TO ITSELF,
and can go MUCH LOUDER (without becoming harsh)
than most 1 inch tweeters in GBP £300 to GBP £10,000 speakers 
(because of our British notch filter)
I believe (but I have no proof) that 
the "High Tech" tweeter uses SMALL VERY POWERFUL "rare earth magnets"
that has been hyped up in some fashionable Hi Fi magazines
as sounding much better than ordinary magnet.
No, I do not have a scientific explanation for this particular Hi Fi magazine hype !
Human voice that is BETTER THAN ELECTROSTATIC SPEAKERS.
MONEY BACK GUARANTEE (less shipping cost, within 30 days)
ON THIS UNBELIEVABLE POINT (until you do an A B testing between these speakers)
The sophisticated mid range uses a coated paper cone.
Young's Modulus shows that
paper is much stronger (FOR THE SAME WEIGHT)
then metals (except Beryllium) and modern plastic hyped up in hi-fi magazines.
Young's Modulus is for ONE BIG PIECE of the material.
Carbon fibre, glass fibre, woven Kevlar is
MUCH MUCH WEAKER than ONE BIG PIECE of the material because ..........
The fibres will "slide" over one another,
so the strength depends
on the inferior strength of the adhesive
(         or the inferior strength of air, because ...      )
( how can you glue ALL of the thousands of fibres, )
(  without getting a bad glue joint on a few fibres ?  )
If the Young's Modulus of the adhesive is better than the fibres,
you might has well use the adhesive on its own,
WITHOUT THE FIBRES !
On top of that, coated paper has far superior MECHANICAL LOSS
which quickly dampens any cone break up / resonance / ringing
Metal and modern hard ish plastics have poor 'mechanical loss',
so they are very poor at dampening any cone break up / resonance / ringing 
and they ring like a bell. VERY AUDIBLE AS TOO MUCH UPPER MIDRANGE / LOWER TREBLE
for many 6 inch metal or modern hard ish plastics speakers !
It might be okay to use TINY 1 inch metal or hard ish plastic dome,
because the troublesome cone break up / resonance can be pushed into the ultrasonic range.
(Unfortunately, DVD audio enthusiast claims that the ultrasonic range affects the music.)
The problem becomes much worst,
when you're trying to use metal or modern hard ish plastics for 6 inch speakers,
which usually produces cone break up / resonance / ringing around 5 kilohertz to 8 kilohertz.
The crossover does NOT stop ALL of 5 kHz to 8 kHz reaching the mid range,
so many 6 inch metal or hard ish plastics speakers tend to resonate / ring around 5 kHz to 8 kHz
(and some people will wrongly blame the tweeter),
so human voices sounds forward and 'in your face'
and you get false exaggerated imaging ( excessive high frequency improves imaging),
and it sounds very impressive in the high street shop.
Take it home, and after two weeks,
the cone break up / resonance / ringing around 5 kHz to 8 kHz
makes female voices sounds too thin,
exaggerates sibilance (when a woman says his, it sounds like hissssssk),
and it gets more and more irritating
and hi-fi magazines will tell you to buy GBP £200 interconnects, GBP £1000 speaker cables,
the latest GBP £1000 CD player,
throw away the CD player and buy a turn table,
instead of DOING SOMETHING OBVIOUS, LIKE CHANGING THE SPEAKERS ! ! !
If you can believe what I have written that
OUR COATED PAPER CONES ARE BETTER THAN
HI FI MAGAZINES HYPE ABOUT METAL AND PLASTIC CONES
then you might believe that
human voices on this WELL DESIGNED COATED PAPER mid range is excellent,
and is more believable and more realistic than our best electrostatic speakers.
Our best electrostatic speakers were launched in 1957 (late 1956)
and were very good 50 years ago,
but the treble rolls off BEFORE 10 kHz (unless you are hi-fi reviewer and got a specially selected sample, please read review in an old copy of Studio Sound magazine.)
and female voices sounds muffled (not enough High Frequency) (Please look at the frequency response curves, before you disagree.)
It MIGHT be possible that
female voices on our WELL DESIGNED COATED PAPER mid range
has just A LITTLE BIT too much treble
BUT WITHOUT GETTING THE FEMALE SINGER TO SING IN MY LIVING ROOM
AND RECORDING HER VOICE ON A VALVE CONDENSER MICROPHONE
ONTO THE HIGH SPEED OPEN REEL TAPE RECORDER, WITHOUT WORN OUT TAPE HEADS, PINCH ROLLERS, ETC., I cannot really tell.
THE WELL DESIGNED COATED PAPER MID RANGE IS THAT GOOD !
Female voices on the well designed coated paper mid range is
five times more believable / realistic than the muffled female voices on our best electrostatics.
(Please look at the frequency response curves, before you disagree.)
( DVD audio enthusiast who claims that ultrasonic treble AFFECTS affects the music, might have a valid point.)
I was listening on axis (horizontally and vertically) to make sure that the loss in high frequency
was not caused by the poor polar response of electrostatic speakers.
The bass of the POWERFUL 10 inch woofer on our MODIFIED IN ENGLAND speaker
 is 100 times better than our 3 ft. electrostatic speakers
(you need 14 ft. by 14 ft. electrostatic speakers to get down to 20 hertz).
Our TINY "High Tech" 1 inch tweeter + British notch filter + British Zobel network
is 100 times better
than the HUGE about 2 feet by about 5 inch electrostatic mid range / treble.
( Most audio engineers will agree that 2 feet by 5 inch panels are too big for the best quality treble.)
