Advent New Advent Loudspeaker


The New Advent Loudspeaker is a new version of a speaker system that for several years has been the most popular and most imitated speaker in the United States.

We have built greater high-frequency energy output into the New Advent Loudspeaker, to reflect improvements that have taken place in recording and broadcasting. But the basic idea behind it is the same.

The performance of the New Advent Loudspeaker is due in great part to some important specifics of design and construction. But the key to all of them, and to the entirely new level of value the system represents, is that it is the only loudspeaker system to exploit the full potential of two-way loudspeaker design, with no attempt to withhold anything for the sake of a more complex, expensive model.

A two-way system has basic advantages, both theoretical and practical, over any other way of designing a full-range speaker system for the home. They include:

Less interference between drivers than any other practical system, yielding more uniform characteristics over the listening area. A single speaker would be better here in theory but in real use lacks either the range or power-handling required in the 'best' category, or both.

A better transition between drivers than the three-way system, because there is no need to sharply cut off the operating range of any driver. Whether such a cut-oft is made for good reasons or simply to satisfy the arbitrary parameters of three-way design, its ill effects are audible.

One simple crossover network instead of the two more complex networks needed in a three-way system.

A cost significantly lower for excellent sound than that of an equivalent system of three-way, or any other, design.


Type: 2 way, 2 driver loudspeaker system

Power Handling: 25W

Impedance: 8Ω

Sensitivity: 89dB

Year: 1979

I picked up a pair of these speakers at my local Goodwill for $11.00 that needed re-foaming. Ebay search had a re-foaming kit for $29.00, an easy fix. I just picked up again at the Goodwill a Sony TA 1150 amplifier for $3.50. It nicknamed "The Mac Kill" because it was said to be as good if not better than the McIntosh amplifiers of the time. Together these sound great. The Advents Loudspeakers and the Dynaco 25A speakers were the best of the 70s.

So cool. I just found out that my father has/ soon to be had a pair in orig. box, etc in storage. He bought them in the 70's? I remember them and look forward to testing them with either my carver seperates, Onkyo or Denon receivers. Love the vintage look.

Anyone know the history behind the development team (er) of these, aka what they were modeled after, etc.

Take care

re: New Advent Loudspeaker

As I recall, and it's been awhile, The Advents were to improve the sonic characteristics of the AR 3a (Accoustic Research) and price point, which were the standard medium size speaker system of the day. I didn't care for them. I started with a pair of Dynaco A-25's to go with my Dynaco Tuner and Integrated 40+40 watt amplifier kits (both bang for the buck at the time) and later upgraded my speakers to the Advent, a very ear pleasing choice. I have repaired both the Dynaco A-25's and the Advents successfully, however, years of use, possibly humidy and the nature of foam surrounds took their toll and I've moved on. I remember them fondly though.

re: New Advent Loudspeaker

Love the Dynaco I have the 25A and my original 35A that I bought in 1975
