Has anyone tried stocking-up two pairs of LS3/5As? I've heard good reports about this from some HK users I believe.
THis is how I heard they do it. One pair upright and the next upside down in parallel. What a way to correct that problem about woofer mis-alignment. cia, it's time for you to get a mate for your LS.

If a Harbeth comes along, my Rogers may want to consider her as a mate.

Harb sounds like a man. Why not the more fem spendor?

No, I have not tried this.
My concern would be the distance between the two tweeter, assuming that the listening distance will not be greater than 4-5 meters. For a greater distance, that would not be a problem.
Beware not to mix the 15 and the 11 ! ("phase" problems, but I do not know if "phase" is the correct word), nor two 15 ohms with different ages.

Hi to all,
On james inquiry, Tried doing this twice before. Once was with 2 pairs of limited edition harbeths( H-80160, 80261) and then again with 2 pairs of rogers 15 ohm white belly ( 24584 and 21076 - supposedly gamby's pair ).
I did it the same way as splendor described. My opinion is that though it did present a bigger soundstage and taller images somehow i felt it lost the cohesiveness and coherence of a single pair. Imaging and focus was rather vague. Instruments that were on the right on a single pair of Ls now occupy the middle too and somewhat blurrs the center image.
I don't know if was doing this right, i might have missed something in the set up so please advice if you guys can think of something wrong with what i did. Though i have'nt tried reversing the phasing on the top speakers yet.

I think Moz can chime in. He knows of people who stack up two esl 57s. I think Faye Dunaway has that kind of set-up, right Moz? And why not the LS?

May be the problem is that the 2 speakers of the same side are not drived exactly by the same signal because the signal travels through 2 distinct crossovers. Phasing pbs ?? |

Stacking LS3/5A's might not easily get the same results as stacking ESL57's. In the 57, stacking creates very large bass unit to counter the limitations of the bass panel's design. Phase integrity is achieved when a single amp is used to drive both units. Impedance is also flattened out compared to a single panel's/ This is simpler in the 57's than with the LS3/5A's complex xover as shushu has pointed out. In the 57s bass extension and power is improved by stacking. Here's Faye Dunaway's stacked ESL's courtesy of Francis E. Halaburt  |
