[Vintage-Audio] Why Was The AR and Advent Speakers Special?

[Richard Boogher]

Duane,
I have always been an Altec fan and have owned several Voice of The Theaters
over the years. I have for my main 5.1 system a pair of Model 19s which I
bought new in 1978. My first experience with the AR 3a was when a friend
brought one over and hooked it up to my system as the right channel with a
VoTT for the left. The sound was amazing, at high levels in a normal size
room there was virtually no difference between the two. Very linear and low
distortion. Quite an A+B comparison test considering the VoTT are (were) the
standard of the industry. The Ar's were about 1 tenth as big as the A7's and
sealed box (acoustic suspension) design. They used a lot of power to achieve
the sound they put out, not very efficient. As I remember Henry Kloss was
behind the AR's and Advent. The 3a's are very impressive. I was driving them
with a Crown DC300 at the time.

Hi All,

Can someone tell me what it was about the Acoustic Research speakers that
made that so popular and different?

I am told that the same man who came up with the design for the Acoustic
Research speakers also designed the Advent speakers. What was special about
the Advent?

Since both systems use infinite baffle cabinets and no ports, how do they
improve upon the low end response of an eight inch speaker cone surface?

Thank you for sharing your wisdom and experience with me.

FYI: I do have a very nice pair of Advent model 2002 with an eight inch and
a tweeter. I had both eight inch rebuilt because the foam suspension had
broken down completely. The cabinets and grill cloth were in excellent
condition. It cost me $100 to have the speakers professionally rebuilt.

P.S. Due to my health issues I am being forced to reduce the current
resident population of audio gear, speaker systems, electronic gadgets that
currently live here.  I wish one of you guys would buy my beautiful totally
rebuilt H.H. Scott LK-48B integrated stereo amp and H.H. Scott LT-110 FM
stereo tuner with manuals.
