    Hi Yip, My understanding is, bigger image indicates too much room reflections and/or less than ideal drivers integration. I ve followed for years my dealer

      Hi Yip,

      My understanding is, bigger image indicates too much room reflections and/or less than ideal drivers integration.

      I've followed for years my dealer friend's set up of his showroom's Avantgarde Trio Classico with 2 bass horns. Initially with the original passive crossover, together with extreme wall and ceiling absorptions and corner bass traps that makes the room almost anechoic. The sound stage size is bound by the area within
      the boundary of the edges of the speakers, but image is not very solid compared with my own dynamic Tact speakers set up.

      Later, he became a Tact dealer as well, and he used the Tact's active
      crossover(with proper drivers time alignments) and amplification, together with Tact's EQ and/or room correction, he was able to get rid of most of his room absorption material together with it's anechoic effects (which I personally dislike for its unnatural effect). And he was able to keep the sound stage within the boundaries of the speakers as before, yet, with solid images and smaller size of the images like that of my own system!

It was an interesting exercise, the outcome a little unexpected. Take image size and dynamics for example: Avangardes are known for their life-size images and dynamic prowess, which you would expect given their size and highly efficient horns. What was unexpected? The little Harbeths had an image sized nearly the equal of the horns. Not! Yes, 'twas so! Okay, the image size of the Harbeths was a little smaller but not by much - quite some stunt, for a small two-way monitor loudspeaker to sound like a big speaker. The Duos kicked the Harbeths' fanny in dynamics as you would expect, but that's not a criticism. It's the same outcome with any box speaker going up against the Duos. Having said that, if you don't have a pair of Duos in your listening room to compare

        > Yes, I'm certain it was the old Quads. The review was in the mid to late 1970's as I recall, but I can't recite the issue. It wasn't full review - sort of a mini review. It was before the ESL-63's were on the market.
