The 'Spitwad' dust cap is stock and critical for the response of the woofer.Used Large Advent for sale on 300+ second hand hifi sites & shops. The woofers were a 11' basket using a 9.5' woofer. The smaller advent is a fine speaker and sounds similar to the LA while taking up less space. The smaller advent was a 4 ohm speaker, and the only 4 ohm speaker of the original line.
The Advent Loudspeaker Specifications m Sidebar: Specifications Description: Two-way direct-radiator loudspeaker. The Advent was my first serious speaker system, inspired by the Stereophile review. Advents also got pretty good press in Harry Pearson's mag, so that helped.The Advent Loudspeakers Finally, a review and demonstration of the Advent Loudspeakers I got a while back. I think Advents probably had better dealer incentives than AR, which management left dealers cold, or that's the scuttlebutt.
By 1970 Hafler had hired Erno Borberly and Jim Bongiorno who were responsible for engineering some of the solid sate amps and tuners. By the early '70s my impression is that Dave was really out of the 'design' end of it, but concentrating on marketing (and thinking of selling the company). He drove over and auditioned some already made prototypes, and chose the one that fit in best with his existing product line.
Highly recommended worth the cost. The result was good from the start but improved over time. I replaced a damaged woofer on a large Advent speaker. We present 11 contenders that aim to make.
Large Advent Speaker Drivers Was Also
The aperiodic thing has bugged me since the first review of the A-25 I read in Stereophile so many years ago. When Aperiodic took umbrage at the characterization, I was motivated to second what Dennis said and explain the reasons. For those of us who were around back then, looking at these speakers today is analogous to what it would have been like in 1970 to comment on speakers that were designed back around 1920.That said, when Dennis used the descriptive phrase "nothing burger" to characterize the aperiodic thing, this was on the mark. It would have surprised me if Dyna ever did any in-depth and in-house loudspeaker R&D.It is good to point out that these speakers were all designed 50+ years ago. Hafler states that the SEAS supply chain was stretched due to Dyna's large quantity orders.Buy SS Audio Recone Kit for 10 Inch Advent Large Advent, New Advent, 6 Ohms, RK-Advent10: Speaker Parts & Components - Amazon.com FREE DELIVERY possible.My guess (and it is only a guess) is that SEAS was able to promise enough of that particular ready made item, and since it was 'good enough' in the context of a price point, that's what they went with. So the choice of drivers was also dependent upon non-audio factors such as initial cost of acquisition, how many could be produced in a given time to meet expected demand, ease of manufacture, expected dealer margins, etc.
I have also designed dozens of systems. I have looked at and measured many more. I have designed over 25 different raw drivers in my career. I have consulted for a dozen more companies. This when speakers were still made in the USA. I also owned a small OEM speaker mfg.
That does not mean the whole company is crap.Again this was a time in history when raw drivers were measured differently. Sometimes sales or a manager wins out. It was not meant to be magic, just a means to an end! I bring up my background only to say I sat in many design meetings over the years. They worked based on the driver I was using at the time.
Nor do any of the other posters I have read to date? Dynaco the company had a very solid reputation in the industry during this time!Many of the statements not just yours could use a lot of supporting data behind them. Was it just snake oil produced to make money. I'm just amazed how brutal the attacks has become on Dynaco the company and the A-25.
I have no way of fully knowing more about the A-25's complete design choices without being in the design group during that time.This will be my last post on this subject. To say its a "Nothing Burger" would not work in an engineering paper, without detailed supporting data. If I chose to really publish something at an engineering level I would want to do a lot more research. Not so much the concept, but why Dynaco chose to use it in the A-25 system?I'm just not sure what point your trying to make in several of your posts? Aperiotic venting is just snake oil? Dynaco is a terrible company? To me, Aperiodic loading is just one of many means to an end for a final design target. Just like I try to at least stay open on Aperiodic loading. There have been some recent engineering papers written that claim the air forces in a box are not truly linear? I would not want to label this as true without reading a lot more about the subject.
It is so hard these days to listen to speakers/headphones/earbuds before buying them that ideally these reviews are a great guide in replacing older equipment. I do think reviews of vintage equipment are valuable when the equipment is performing close to the original specifications. So everyone can post what they want!Thank you Amir for this review.
The Polks sounded better than the Advents to me, but not thousands of dollars better.I still enjoy my Legacy III's very much but I do sometimes wonder what the next step up would be. It's been too long to remember a lot of the details but it involved Polk tower speakers and a Sunfire power amp. One very kind dealer spent a lot of time with me demonstrating a rather expensive showroom system he had set up. I was always a huge fan of Julian Hirsch's reviews and purchased my Legacy III's based on his tests and write-up for Stereo Review:I lived in a large city back in those days and did get to audition quite a few speakers before making my purchase. After reading this review and the comments it seems like the Legacy III perhaps corrected many of the quirks associated with the pre-Jensen Advent line. I thought my Advent Legacy III's had more in common with the NLA than they actually seem to.
I don't think we're going to reach a consensus on the aperiodic loading issue. After getting the Legacy III's I stopped using an equalizer and with my current amp just slightly boost the higher end with the treble control at approximately the 1:00 position.Anyway.a fascinating review and comments.I've wrapped up my work with the A25, including a revised crossover that I think is a significant improvement. Likely for that reason the slight dip measured in the midrange between the woofer and tweeter doesn't bother me as it's approximately how I was adjusting other speakers to be anyway.
