Pro Noblem!

I'm keen to see the 'booklet' in question myself and scan it into the archives here.
Confirmed that it is safely in a vault in the wildest North Cotswolds, will collect during week and post on saturday.


Andy.

Well here I am with a gold embossed burgundy coloured Maidstone Installation Manual.
By the looks brand new and unissued…

The first eight pages dedicated to a brief history of Kent Engineering & Foundry.

Moving quickly onto the contents one is met with an interesting introduction to the 109s design with some attention-grabbing pictures.
These include a few personnel, the prototype is also shown being tested with the reflex ports held on with masking tape…
The response curves are fascinating and we also have the crossover network schematic but without component values.
Some pages relating to setting up the magnificent beasts.

I shall take it into work tomorrow and photocopy as well as scan it onto my laptop.

When I get to the local post office on Saturday it will be dispatched via air-mail.

Enjoy!!!

My utter pleasure!

I'm in the process of photocopying at the moment, will try to scan in and convert to PDF file or whatever you wish...

Thanks for putting the information up on the site.

I read it yesterday, I would love to hear these speakers, does anyone know how many were made? I have never seen them for sale anywhere, what sort of prices do they go for these days?

Good questions.
I would like to know as to how many were sold in the far East and how many in Europe and USA.
I have only ever seen one for sale as "Pre-Used" sadly I cannot remember the price.
In a very hostile environment at the Bristol Show they were very impressive indeed.
I wish I could have had a listen to some of my music in a decent room.

Oh, the manual has been sent today Mr O''blocked word'. Let me know when it arrives please.

I did talk to Andrew W., and the approximate number sold is around 100. I think think that most went to the far East. Vistisen, I paid dearly for mine, but they're worth every penny and more from my point of view. There is no set price though, and you may get a great deal - the trick is finding them. Nothing is impossible to find. For me they define what is possible from a loudspeaker in terms of reproducing a credible approximation of what a live performance actually sounds like.

Oh Yes!

Without any doubt dynamic range is the secret.
If we know the music well enough then it will sound great on anything and produce the right emotional response.

However, dynamic range is the secret with no compression whatsoever.
Efficiency and loads of watts!

I have heard some extremely coloured speakers but driven with large amplifiers in small rooms and I have been left breathless and speechless.
This will work equally on classical, opera, jazz and even popular music if it has not been murdered in the recording process.

I have seen the tweeters on 104aBs catch fire as also the electrostatic panels on B&W DM70s, all in the quest for dynamic range which changes in proportion of how much good wine or malt whisky you have consumed.

You have to ‘Move Air’ with ease and the R109s with the right source and amplification sure did that!

Proffski have you been blowing up your tweeters? Laughing Just kidding!

You are spot on in your observation that dynamic range and the speakers ability to deliver micro dynamic nuances and macro dynamics without distortion plays a very key role - especially in such demanding music as Opera and Classical. I'm familiar with the 'sound' of some very coloured speakers, and I have been impressed with some of the better horn/compression driver systems AvantGarde Trio, JBL Hartsfield, JBL 4350, JBL Everest and K2, Jensen Imperial, 15" Tannoy Red in GRF corner cabinet, AER Lowther type drivers etc. All these speakers are compelling but are not without drawbacks though. The sound can be breathtaking in terms of dynamic response and that is why some of these horn/compression driver speakers sound so compelling to many who hear them for the first time. The Maidstone also has that same sense of dynamic immediacy and scale that the best horn/compression driver systems do so well - and many lower efficiency speakers do struggle in capturing this.

Not blown any tweeters for sever years now, but in my past.. Oi, oi, oi...

Again agreed, the sheer power of a massed choir, or strings, a brass band. Just not do-able on small speakers.

Amplifier must have oodles of headroom as must the speakers, and I most certainly am NOT a dB freak either. Smile

We are all awaiting the more concise report on the Maidstones when you have the time!
