Quad's specifications for the two speakers do indeed indicate that the 2912 goes deeper in the bass frequencies but only marginally so.. I have a vague recollection of reading an American review of either the 2905 or 2912 which exhibited a bass 'hump' around 50 Hz on test, in the...

As you may have gleaned from what information is available on the internet, the build quality of these amplifiers was a cut above most contemporaries, which was reflected in their high selling price in the mid 1950s. In some ways, they were ahead of their time. They still sound remarkably...

IIRC the Quad Service make a one off labour charge per speaker which I think costs circa £100 each plus a further parts charge for panels and other electronic components as required As a previous poster on this thread has commented, if multiple panels are fitted then the unit cost reduces...

Although, I own ESL57s , I am not immune to the charms of the later models . My favourite 'new-generation' model electrostatic is the 2812, which I also feel, has a better integrated bass than the larger 6 panel 2912. If you have a suitable room, then the larger Quad speakers could well...

Hello Pablo, If you give me a couple of days, I should be able to send you some images of the underside of one of my HF25 monoblocks. This amplifier is a later version and features the revised, factory circuit as documented above. Although professionally overhauled it retains the original...

Eoin, at the price point you have indicated, if you want a decent / serviced pair of Quad 'stats,, then you are realistically looking at either ESL57s or ESL63s. Either model will produce around 94 / 95 dB which should be sufficient for most people's domestic needs. Quads do very good...

As Tony has commented, you should be O.K. In this instance. it appears that the leakage is minor and it is doubtful whether the past overheating issue has compromised the integrity of the windings.

To add to the good advice already given, the vital rule to observe when transporting electrostatic loudspeakers in a car, is not to subject them to sudden or violent movement. If braking, for example causes a speaker to jolt / move suddenly, the risk of panel damage is increased. Should...

Ditto with the balance 'slider' on my Quad 22 pre-amp.

Although some may disagree with the assertion that 'classic' output valves have different sonic signatures, I have always thought that good EL84 amplifiers have an exquisitely detailed and articulate sound which is revealed to its fullest extent by low-distortion, highly accurate speakers like...

Like you, I also prefer the sound of the four panel 'modern' Quad electrostatic speakers to the larger six-panel variants. IMHO, the bass performance is much better integrated /seamless with, for instance the 2812 when compared to what seems the 'semi-detached' bass of the 2912 model. The...

Splendid work. Well done that man !

I don't think that cable length is your biggest concern here. Although not technically savvy enough to give you a definitive answer, I think that you will struggle to get these modified versions working properly in a domestic system.

From distant memory, I think that this may well be a high-impedance version..
