If you think it would be helpful I could publish your info on this site. I also have a couple of Dalesford drive units - in the loft. Is it copyright free? Terry


As may have been already mentioned on the forum recently.
With the help of Colin and friends the Dalesford Constructors Book will soon be published on the new Falcon Acoustics site.

If anyone ever reads a new post on this old thread; Comment was made about Dalesford speakers not being any good for TL speakers. I have a pair of LNB Paralab 40s and apart from the Coles 4001 and HF1300 there appears to be a Dalesford 100/200 for the bass. Not sure how good it is but I will find out when I make a new front panel and fit a KEF B200 1022 and try that.
Any info on the Dalesford unit would be gratefully accepted!

The Thiele / Small parameters for the Dalesford 100/200 do not lend themselves to Labyrynth loading easily, but it is certainly feasable.
I can send you the Dalesford sheet if you wish with the parameters for the driver in question.

P.S.
Western Audio Research in Cheltemham used Dalesford drivers in many of their designs, I bought much of the stock years after they went bust.
I cannot figure out as to why they are called WARS here, it was just W.A.R. Smile Ive sent you a P.M.

In fact the Dalesford Data Sheet can still be found on the FALCON Acoustics site here: http://www.falconacoustics.co.uk/downloads/Dalesford%20Speakers%20Datasheet.pdf

...and the Dalesford projects book has meandered here: http://www.falconacoustics.co.uk/falcon-archive-links-history-tips/falcon-acoustics-archive/dalesford-speakers-drivers-datasheet/dalesford-speaker-book.html

Many thanks for the info, I had found the Dalesford projects on the Falcon web site but it appeared that their archive material was being updated so did not see the data sheet.
It will be of interest.

O me miserum. Computers; don't you just love 'em!

It's a sad story; one of my Rogers Export Monitor 8" bass drivers succumbed when given far too much level as a consequence of my DAC going apeshit level-wise, then refusing to respond to the volume control. The upshot was that the music was playing very loud long enough to lunch the voice coil (I think) in the bass driver of one of the speakers.

It calls itself 'The Rogers British High Fidelity Bass Loudspeaker - Manufactured exclusively for Rogers by Dalesford Speakers Ltd.'

Reading around I have gathered that this driver had a bextrene cone, and consensus seems to be that its characteristics lent a certain something to the sound of the Export Monitor (which I particularly like) so I'm quite to get a repair rather than an 'equivalent' which I fear may spoil the magic.

I don't suppose there's anyone out there who can advise where I can get the driver repaired, or maybe even might have a spare they could sell me.

Ever the optimist, me! Any helpful advice will be much appreciated.

Joe

Isn't it possible to get the voice coil repaired?
Maybe easier then finding a replacement woofer.

Sorry - I meant 99.9999999999999999%
This company has told me that there was only ONE incidence of them not being able to fix a bass unit in all the time they have been in existence.
They are currently working on 4 of my Goodmans 8" drive units from the Achromat Kappa/Sigma range - the ones with the Hitachi patent V-pleat surrounds.
When I was there, I saw brand new - just manufactured B110 drive units.
Amazing.

Hello Proffski - it's Mr Quackers here - am I allowed to give details on the forum? - I don't want to be accused of advertising although I have no connection with the company.
