Nobody doesn't like Dynaco A-25's.

So he's saying that diffraction is not a problem? Is that just in reference to stacked A-25's, or in general?



I've never been able to stomach Pearson or his magazine.

Peter Aczel has made some comments about Pearson that are right on target. :)

Whether or not you like/respect Pearson, thousands of people followed that original article in '73 about the stacked Advent system. I could personally take it or leave it too. But.., I quoted from his magazine, so I thought it only right that I identify whom it was that made the statement.

I imagine that someone could piece together a nice surround sound suite of these A-25's, or pair them with a decent sub and have a fine 2ch rig. You've given them a proper E-Val. and I enjoyed it. Thanks Jack.

I use the A-25 (pearls before the swines...) as Rears in addition to the ScanDyna A-45x (which ar supported by a 80liter 10" aktive Sub) - a center out of ripped pair A-10's is planned :)
 
Would the folks here that have the RTAs please post the make and model, along with the microphones, please?

Ain't saying I'm gonna go buy one, but it does look like fun. :D

You'll know what's up with your system within an hour or so, but it'll take weeks to explore its features entirely.... :thmbsp:

I have a TacT preamp, and it has some similar capabilities, but I've been wanting to set up an actual room and test gear to play with some speaker experiments (ESS AMT-3 midrange substitutes). Thanks!

I have no argument with you for posting the info or Pearson's name. :)

I wouldn't choose to use or not use stacked A-25s based upon Harry Pearson's views. That's why I made the comment I did.

I actually don't think much of most reviewers and audio mags.

Most of the info presented at this site jibes with what others have told me about the audio review industry: http://www.high-endaudio.com/reviewers.html
 
I don't suggest that you stack A-25's based on Mr. Peasron's review. My point is that there are viable stacked systems. Mr. Pearson had nothing much to gain by his comments.
Advent isin't a big advertiser in TAS. What do you say when your opinion about a certain piece of equipment aligns with Mr.Pearson's opinion? Say he's right only certain times?
If I were to post that "Joe Average" has a stacked XYZ system, I don't believe that would carry any weight, at least to the junkie's. Hell, I don't think it does anyway, but..., at least the info comes from a fairly reputable source, about the original landmark system.
Some Ak'ers are content with what they have, whatever it may be. Some of us swap out components a lot to achieve the best system, and that, to do what we like most: listen to and enjoy recorded music.
Some spend thousands of hours on research, chasing the illusive absolutely perfectly flat (measured) speakers or whatever it is they're after.
I fall into the middle group, envy the first group and try to keep a cautious perspective on the third, so I don't end up getting sucked into a cycle of letting machines rule over what my own ears tell me.
I've been a member of other audio sites, that while on first glance claim to be about Heritage, but if you look closer, and don't have pretty much exactly what a small group recommends, you've missed the mark and they'll let you know it in a not-so-kind way.
So, I support AudioKarma. 20k + and growing. Diversity. Respect. SUPERB Moderators and Administration. I'm glad that I can express my thoughts and not get trampled on because I don't fit the mold.
Some people will gleen useful ideas from this thread, some will continue to stack to their hearts desire. My hope is that they can continue to do so, post about it, and be proud to share their stuff, whatever that may be.
I had the occasion to visit another site's speaker GURU. I was there with 2 of my friends. I brought serveral of my reference CD's, so I could do a fairly proper evaluation. I was willing to give credit, where credit is due. This guy's system had all the goodies, and was set up with CLIO. Had TAD Beryillium drivers, with JBL SUB1500 subwoofers. Antique Audio 845 tube monobloc's, DEQX crossover, the works! It sounded HORRIBLE! Lifeless, Bass-less, the sonic equivalent of Battleship Gray paint.
I still respect that it is his system, and if that's what he likes, so be it. The kicker is that this guy is supposed to be a GURU. When we all got into my truck to leave, we didn't say a word, but just looked at each other with the same puzzled look, and then laughed really hard.
Three people with different musical tastes, backgrounds and system configurations. A unanimous conclusion.
If it wasn't for the fact that this guy is supposed to be "it", I don't think the impact would have been near as great.
So you see that just because someone posts a bunch of data, doesn't mean that you cannot thoroughly enjoy your own system just like it is, or how you want it.
Likewise with the data. I think it's just fine that some may really benefit from it.
Just be careful.
 
This thread was about Dyanaco A-25's. At least it was originally.

I've never heard A-25's, but they look so business-like. I'm a proponent of 'Form follows function'. The pics I saw of them without grills...man, they must function well, cause they aren't pretty! And that's exactly what would attract me to them. Like a moth to a flame. Kind of like the Jeep of Audio.

I've been thru all the stacking scenarios. I found out that, in my case, there wasn't much to be gained. Not in a small (12' x 12') room, anyway. But, you know what, I was really enjoying it for awhile having tried something new and different.

Then Zilch stepped in. He pursuaded me to take SPL measurements and dB measurements. I did all that (without capping the vents) and realized he might be correct. In another lifetime (pre-AK) I would have laughed at that suggestion. Gonzo added his opinion. Then I was waffling.

I was like Gilligan, believing the last person I heard. Before AK I just put my speakers in the best spot they could fit in. Over the 30 years I had them I tried many configurations and in many different rooms/houses. 4 corners near the floor, 4 corners near the ceiling, stacked in different ways, all spaced against one wall, etc. Most of the time I just liked changing stuff around 'cause it was fun! And it always sounded good to me!

So I have to give it to Gonzo in the long run. Although my speakers might not have sounded the best they could possibly sound, they always gave me pleasure. But I also liked Zilch's point, that you could always make them sound better.

In the end, I wanted different speakers anyway. (After 30+ years with the same JBL's I had to find out what was out there.) As a direct result of joining this Forum, I just went out and did it. I finally did it!

Now I have my old JBL's stacked atop my 1989 Klipsch Fortes. I don't play them at the same time, however. The Klipsch sound better alone...I think...but maybeeeee...

Hey guys, Please, not on my thread.

Zilch and gonzomeep, you know each other from another place and time. But this thread (Perhaps this forum) is not the place to duke it out about the old place.

This thread is about Dynaco A-25's. Lets try to keep it there please.

Thanks, Jack Gifford :tresbon:
 
Thanks, Jack. I've requested that the exchange of posts be deleted to clean it up....

Right, I was talking about the subject. That is my opinion, based on experience(s) I've had. I cannot help it if one person insists on beating a drum. I've re-read what I wrote again. It looks like it is on topic, taking another's graphs as the absolute bottom line, and about stacked systems. I cannot help the other. I was careful to not be completely dismissive of the work you've done. I am merely pointing out the other side of the coin. I thought that this was a discussion? You mean we all have to have the exact same opinion? I didn't think so. Just because he's highlighted 3% of what I actually said, doesn't mean that his perception of what I meant is what he concludes it to be. I wrote a lot more than he quoted.

BTW, I find it rather interesting that Zilch is trying to dictate or change my attitude. I thought that was a no-no...
 
Maybe I already mentioned it...I'm an A25 (and A10) praiser. Nice how such a simple little speaker can sound so good without being some huge speaker and take up so little real estate. I've had the big old speakers and I still like these little jewels (to my ears) better than the last pair of horn speakers I got rid of that had absolutely no high end. Oh well. I guess that's the reason they sold so many. They appealed to the masses that were on a limited budget.

Very well put, Jack. I suggest that you guys treat this as if it came from the AK moderators. Jack, I think you've posted some very interesting stuff about the A-25's (of course you've made me even more nostalgic for the pair I used to own). Let's stick to that topic, OK?
Thanks,
Rich

Hi Rich, thank you. I would like to know if what I wrote wrt my experiences if offensive? Can you take a look at what I wrote? Thank you.
 
A long time ago I bought a pair of A-25XLs at Musicraft. I liked the sound but I popped the tweeters trying to get loud (the amp was a Dyna 400). So I bought a second pair of the speakers and stacked them.

Regardless of what might have happened to the frequency response two pairs gave me lower distortion and increased dynamics, those are good things IMO. I was much happier using two pairs than using one.

Tom, As has been said here before, "Your mileage may vary." And there is no wrong way to play them.

This thread has proved that no matter how you like them, stacked or not, the A-25 is a great little speaker. No wonder they sold over 600,000 pairs.
