richard replied to Aadams's topic in Acoustic ResearchThe AR 3a was a favorite of mine and imaged well. I am a fan of SACD surround, and recently purchased a pair of AR 9s. What amazed me was how the 9 s image with stereo. My listening room is about 19 feet wide by 27 feet long with 16 foot celing. I love chamber music, and the stereo image is about the same in front of the speakers as well as over 20 feet away. Part of this may be due to the height of these speakers, about ear level in a standing position. Even so, when in a seating position over 20 feet away, the image does not change much. Yes, I bought these speakers with the improvement in dynamic range in mind, but the stereo image in all parts of the room was a real surprise.
I am new to this forum. The speakers I have had over the years include the AR 3, Klipch Cornwall, Acoustat model 3, Polk, and the large Velodyne ULD series. Over the years, I have played the violin and viola in various symphonic and chamber music concerts. The AR 3s were a great speaker, and had many inovations for their time. As time went on Teledyne's last great product was the AR 9. I wished I had purchased them 32 years ago. (That kind of gives away my age?!) The line up in the AR verticals was by far their best product in my my opinion. The 9s have the ability to reproduce everything a large symphony can dish out, and yet the smallest detail in chamber music can be heard with great clarity as well. I believe AR speakers were made for acoustic music. The smallest speaker AR made was the AR 8 B (about the size of a shoe box), yet the sound is anything but! I use these small speakers in by bedroom and the sound is very convincing. Bottom line is for acoustic music the old AR s can't be beat, or even equaled. (Yes, I may be getting older, but my ears are young)
