But the A version was so inefficient that it made an LS3/5a seem almost like a high efficiency speaker. There was almost nothing to drive it reliably in the late 60s when it came out. I recall a figur .......

The problem is since Thiel/Small made designing ported boxes fairly easy and since ported boxes are more efficient and sound like they have more bass even though it's inferior bass, good closed boxes .......

do they quote how far down the 24 Hz is? Perhaps 10 dB as I've seen sometimes. If it was 10 dB down then the box resonance could easily be in the mid 40s(I believe the old AR3 was 40 Hz). And 10 dB do .......

It still is a ported speaker. But here's some trivia to make you feel good(incase you didn't know). Gordon Holt loved ATC speakers and reviewed a 5.1 system in the early 2000s. After he left Stereophi .......

But it's ported and I'd have to see if it rolls off in the bass at 12 dB/octave like a closed box(like Rockport claims for their ported speakers). But they'd still be unloaded below bass resonance lik .......

Can't resist this since it's not really on the subject but I'm always bothered that most audiophiles and audio critics use the term acoustic suspension and sealed-box interchangeably. The definitions .......

The larger ATC speakers are ported. The port is visually obvious. However they do use the port differently according to their notes. It's tuned to limit woofer movement in it's operating range, not to .......

The question is if harmonic and IM distortion are the most significant factors in poor sound. I once had a demo of a tube amp with variable feedback(15 dB to 0 dB). As the feedback was reduced the dis .......

Two suggestions for the rebuild. 1. Put the crossover in an external box designed to be acoustically dead with ant vibration feet. Microsonics are a significant source of altering the audio signal in .......

The Stereo 70 came after the MK 4 mono amps and was a stereo version. It was done probably by the people you cite over a period when David Hafler was away and he learned about it when he returned. But .......
