directional speakers


I just bought a Bacch4Mac bundle and am thinking of upgrading speakers.  Theoretica recommends speakers that are more rather than less directional.  I currently have Spendor S3/5r2 speakers.  No complaints at all, but I've thought of upgrading to Harbeth 30.2, Graham/Chartwell LS/6 or maybe Fritz Carrera BE.  Love the BBC mid-range, but I have no idea of how to find speakers with a tight rather than broad sweet spot.  Any advice would be appreciated.

Budget is in the neighborhood of $5000; used is fine with me.  The speakers will be placed in front of bookshelves filled with books.  I could place the speakers 18" to 24" from the wall.

I rescind those recommendations that I gave. I don’t think they are as directional that you are looking for!

@treepmeyer posted, quoting from Theoretica’s website:

"An ongoing investigation of speaker directivity at Princeton University’s 3D3A Lab, has shown that dipole speaker designs, electrostatic speakers, as well as speakers with horns and waveguides offer significant advantages in 3D imaging with BACCH® 3D Sound in highly reflective rooms..."

Very interesting. These are pretty much the same conclusions I arrived at in my own explorations of loudspeaker design and room interaction (for unprocessed two-channel stereo). I like some of the attributes of dipoles and some of the attributes of horn/waveguide type speakers.

Well, that’s a lot of work for BAACH. :D

It’s well known that the more reflective a room the more treatment is needed to achieve the same level of satisfaction in detail. That’s not at all new or outside of prior work in acoustics.

In a modestly treated room, the Fritz with ring radiators do pretty well, but they benefit from some treatment.

Alternatively, along the same lines of thinking, if you can put the speakers well out into the room, as well as the listening area, you achieve the same goals.

Maggie 3.7i’s should sound great with your Baach.  They don’t have a high Wife excepting index, but they really do sound nice.

All the best.
