Well if they can make Ryan Adams sound superb they must be bloody brilliant! ;)

Seriously though what about a photo. We need to see these monsters.

[hifi_dave]

Didn't realise they made so many speakers - you must have bought their whole production !!!

[dantheman91]

Hi

Well apprently when the owner of the company died the burnt all the speakers that were left in the factary.

on closer inspection im left wondering are the drivers original.?



Dosent really matter still produce a thundering sound none the less.

[dantheman91]

Original drivers guys :eek:

[DSJR]

The smaller ones certainly used to thunder - the LP12 HATED them..

Hi

Hoops yeah i contacted stu. he bought my dads old ones from him the only pair left of the range. stu is a top bloke and knows his stuff. try putting them in a flat with other hi-fi around is not ideal :scratch: but loving the horns at the monent spine tingling is the word.

How are you finding yours.?

[hoopsontoast]

I dont have them any more, I donated them to Stewart (I only paid £15 odd iirc) for his expanding collection :)

[dantheman91]

Hi

thats a shame.

Thats cool, they were made in southampton so the were probobly sold local to me. 2 pairs have apeared so far. wonder if any more are in deepest dorset.

[hoopsontoast]

I would love a pair of Beaulieu's

[dantheman91]

:eyebrows:

We had them hooked up to a leak ST 20 very sweet and detailed sound.

Damn shame we sold them.

IAS loudspeakers were produced over a number of years. We made a few models which all used a 1/4 wave back loaded horn system. We NEVER used complex crossovers, rather we built and designed the crossover to work with the very best drive units we could get hold of. We even used SERIES crossovers with very low roll of rates which impacted on the music very little. Although to the end of the IAS story we went to 12 dB per octave parallel xovers which were much easier to build. The stock was NOT BURNED when my partner Allen Willis died, the company was wound up correctly. So all stock was sold to local buyers usually at Southampton Uni.
The cabs you have are a pair of EARLY Cadnam Export. These were the top of our range of loudspeakers much much better than The Bealieu l/s. They had more bass extension, tighter bass definition, and a much more extended treble reproduction. The Bealieu was a flagship model which was surpassed by the rather large Double Bealieu which had a Volt B250, along with another bass driver, again a Volt 10 inch driver which had a HUGE magnet, these were placed in two horn tracks! We used an 8 inch Volt midrange as well as an Audax two-34 treble unit. These l/s were huge, about 5 foot tall about 25 inches deep and about 15 inches wide.

Hi
:eek:

Sorry i was mis infomed.

Stu your a top bloke thanks for the info. these speakers are so rare its amazing i found a pair this time. might get the covers re done etc the cabs are in good order. luckley the were just up the road from where i live.

To recover the grilles all you need is some Polyester Dress Cloth, from your local haberdasher, if in doubt take one of the grilles with you, this should cost you no more than a fiver! You will also need a staple gun and some staples of no more than 1/2 inch in depth, grille covering was done just before the l/s were boxed up to be sent to the new owner.
We also used a measuring machine for all the l/s build to make sure they were built to spec. Then they were all listened to for about thirty hours or so to again make sure they had been built correctly.
Although IAS speaks are very efficient they all had an impedance of about 10 ohms or so so I would advise you to use an amp of at least 50 or 60 watts to get the best out of them.
All of our biggest cabs were developed to SOUND GREAT and were not as room dependent as most of our competition. I run my Beauliea on a 650 watt amp as well as the Ashurst. They do need loads of current to keep the bass tight.

ps if you ever need to shift these speaks on..................................they could return home!

Hi

Dan, any chance of a decent picture of the speakers of yours? You know, one or two that aren't avatar sized? :lol:

C'mon, play the man Dan :D

[dantheman91]

[Reid Malenfant]

[Reid Malenfant]

Cheers for the pics Dan :)

Do they look right to you? :scratch: Have you seen any pictures of the same type of speaker elsewhere?

What model are they?

Sorry fella, they just look wrong to me in so many ways :eyebrows:

Hi

Apprently there original i asked stu wen.

[Reid Malenfant]

Well you do surprise me, but I'll take your word for it & stus' :)

In comparison to the Beaulieu they look like drivers out of an Amstrad rack system, with a piezo horn & dome tweeter thrown in for good measure :lol:


As I say, they just don't look right :scratch:

[dantheman91]

Hi


:eyebrows: I think they sound pretty damn good but thats me. As i have confirmation from stu. i asked the last owner have the drivers etc have been changed she was an old dear she said no,

[Reid Malenfant]

Well obviously I can't comment on that side of things :) Sorry, I really don't want it to seem as though I'm dissecting the things, it's just that the Beaulieus looked like high quality speakers, they were fitted with Volt drivers after all ;)

Where as I honestly can't remember any other speakers fitted with chromed dust domes other than Amstrad :rolleyes:

It just doesn't sit right in my head, maybe I have got a problem? :facepull:

Hi

There richard allen 8 inch drivers and i think also a richard allen midrange, a motorola horn and audax tweets. but i havent taken them out to check but its the sound that they produce is the main thing.

I also though they wernt original but i was wrong as these speakers are so rare theres no way of knowing aprart from stewart.
