Hi.
I am looking for advice on speaker placement. Nearfield
I have a pair of 104aB's , and I am finding it hard to ESTABLISH EXACT `FOCUS' on the second speaker. with the drive units being offset from the cabinets I am looking for an easy way around this. any help would be great .
Thanks, Hector.

Hi,
If you use or have heard of this method, you will not have to look at the link, it's how its achieved the holographic sense of depth .
My problem is with the 104ab's, having the drive units mounted on the left hand side which in turn is making it hard for me to achieve the exact same angle of axes on the second speaker, I have used this method now for a few year, and focus can sometimes be a hit or a miss .
I am just praying that someone with 104's that also listens to Nearfield. will see this and it wont be double Dutch.
And also . pleas,

Speakerguru.

I think you might be the man,,,,,
I have used my +&- to tweak the rear sound stage back into centre on the odd occasion, with good results.
but can you explain to me what there intended function is,
If it's to balance one side or the other, what happens if both are at the same, like left and right both set to +.
THANKS
,Hector.

I used to have the 104aB and do not think you were supposed to have different settings on each speaker, since pinpoint stereo needs good matching between the pair. One forward and one backward response is unlikely to help good imaging? The control was meant to compensate for either dull (very heavily damped) or bright (hard surface) rooms, but in good rooms always in the centre position. I suppose you could turn both up for dull recordings and down for glaring recordings but might get fed up rushing to the speakers each new cd.

I used them in the BBC style for low colouration speakers, near equilateral triangle for speakers and listening position, speakers toed in to almost face the listener, or cross just in front, away from back wall a distance greater than the stand height, a greater distance again away from the side walls.

Wat's a ''cd''.
I only like vinyl , its got a much better sense of depth and separation between the front and rear sound stage with the speakers in the placement that I have in use .
cd is allot flatter and two dimensional in comparison .
I often do a like for like test cd-v's-vinyl, to let people hear what can actually be achieved and especially with Nearfield speaker placement the difference is incredible.
Now don't all of you digital heads get your defensive boxing gloves on, I am not interested. I have travelled around for years , just to hear the sound that Jo Blogs was reeding about. and often I would ask to hear what the new age had brought us and to be honest
I think we are going backwards.
The last time being, In a shop in Glasgow, Stereo Stereo. I traveled 400,mile in all.To go and purchase a cartridge for my turntable and maybe listen to something while I was there .
when I arrived at the shop and said to the man, ''that I was looking for a cartridge'' He replayed '' We don't sell ink sunny'' .
MMMMMMMM Good start.
once establishing that he had nothing in the shop that was suitable, I asked ''did he have anything set up in a room that I could listen to''
He huffed and puffed then led me to a room, one with which I was very familiar with. over the years I had spent countless hours in said room, a proper education.
We walked in and i saw. well not what I expected . no lp12. or any turntable. He said it's a thing of the past sunny'', ''you don't get better than this''. then went on to boast about how expensive it was. comparing it to richersounds.
I just kept my £800 and left before the wallpaper fell of the wall.
which looked imminent..

I'll see your "cognitive realism transducers" and raise you

Follow this link. It was create by my old company - Rockwell Automation...

I used to show it at the beginning of every sales training session - the look on the people faces was priceless.

I thought the 105/3 was 4 way ? Anyhow I guess a low value resistor in series with the drive units would have the same effect.

I think it is fair to say the BC1 revolutionised the speaker industry by showing a moving coil design could approach electrostatic performance in terms of accurate stereo, depth, and midrange colouration, was often used as a reference by other speaker designers for midrange and treble performance. It could even have somewhat been an inspiration for the introduction of the Reference series.

I remember my 104(and aB) manual showing the 0 position as "flat" with + and - showing 2dB boost and cut in the midrange, and saying the "flattest" response was in the reference position. The adjustment curve was a little different from the "BBC" dip which tended to be around 1-2 kHz energy since this gave better depth perception with the bextrene cones of the day. Dudley Harwood maintained the dip in his Harbeth designs and told Alan Shaw it was to minimise a colouration in the polyprop cone - amazing admission direct from the "inventor".

I had the 104aB and swapped for the first Harbeth, which had better depth and transparency but not the best tweeter in the 1in Audax, then swapped the Harbeths for BC1s which by then were the higher flux ferrite magnets with higher power coils and lined port tubes, and frankly they were better overall than both. I then got 105s as the closest I could find to the BC1 stereo, depth, midarnge/treble with better bass and higher output.
