In Reply to: RE: General speaker design characteristics for a 2A3 amp posted by Paul Eizik on April 14, 2017 at 11:11:37
Paul Eizik ;
Sorry about the mis post...late night and all that! I am glad that you found it , thanks .
I'll post this question again in the right place...
It has been mentioned , that just because a speaker has the required characteristics large woofer , 16 ohms , 100db. eff. and large volume box's , it may not play well with low power amps like the 2A3 . What else should I pay attention to ?
Please don't delete the post in question as I'm just too lazy to re-type it ; )
A SET amp by it's very nature has a low parts count, therefore changing a part will have a greater impact on the sound than say a solid state amp which may have hundreds of parts. It's hard to generalize unless someone here has tried your amp with the speakers you are interested in. BTW Alan and Lawrence were discussing Alan's Lowther Medallions which I had heard a number of times, as Alan set the record for hosting the most Chicago Horn Club meetings. Most of the times Alan was running Korneff 45 SET amps on the Lowthers which have even less power than a 2A3 amp. There was a Carver subwoofer used and there was never a shortage of power in my humble opinion. Some people object to the Lowthers having a "tizziness" at the top end, and I could hear this on some music, but at one point an inductor mod was introduced (which I forgot the name of) and I never heard the tizziness again. You may run into an issue like this with the BK20's as the Fostex woofer also has a "wizzer cone" like the Lowther (that is to say a secondary small cone near the dust cap to extend the highs). So comments about the Lowthers could be applicable to the BK20's.
Keep us posted on how the project is going and what speakers you decide on.
Hi Paul, we may know each other as you have attended like me to the chicago horn meetings at Alan's? were you the guy who had the Edgar horns?
Ps I also remember the song that Alan like to play it was the house of the rising sun from cyndee peters very nice dynamic song but it rang terribly with the lowthers could have been the amp too dont really know but I remember it very clearly, Anyways very good times in them days.
We undoubtedly have met at some of the CHC meets. The guy with the Edgarhorn Titans was Ray M. who bought the speakers Bruce took to Midwest Audiofest in Ohio back in '02. He built a new house with a dedicated listening room in the basement, and after a couple of meets he disappeared from the scene suddenly. A nice guy, and I often wondered what happened to him.
I'm stick'n to my story that I never had a problem with the upper end on the Lowthers after the inductor mod was added, they were always very listenable and could play anything. If you want to hear some "audiophile screechies" try the YG's at Axpona. I thought they were unlistenable last year. John Atkinson's measurements in Stereophile shows them engineered towards the flat philosophy, which means that the ancillary equipment and source material were selected to bring this out. Their motto is: "The best speakers. Period.". If you're going to the Ax this month you might try bringing the Cyndee Peters recording (which I don't remember hearing) and see if it clears the YG room out. That's quite a personal thing I think, last year one of the CHC guys said that he thought that most of the rooms at the Ax sounded screechy, but I thought that it was maybe 20% that did.
Oh Yea Paul, now i remember Ray and I did attend at his new house somewhere in plainfield? nice looking speakers the little lowthers alan has or had at the time were more dynamic and I still say they have ringing distortion but some people just don't hear it, its all good my hearing is exceptional I have bat hearing you know? every time I would go to my parents house they have this outside device that is suppose to deter wild animals like raccoon etc, I can hear that very well I used to ask my parents (don't you hear that its very annoying) they said no they don't...but all my senses are acute somehow.
anyways Yes Ray I wonder what happen he was very impressed with my little single ended amplfier he would talk about it all the time ...his wife as i remember was not too keen with his hobby esp in the new house.
How time flies
Last I heard from Ray was maybe 12 years ago? He mentioned wanting to part with the Edgars that last email, then he went silent. I think he just soured on the whole scene, I have some suspicions on why, but it doesn't really matter.
I liked Allen's set-up, he had a nice balanced system. Yes, the Lowthers could tiz, but every system is a compromise. His was one of the better compromises.
I don't know if you were at Ray's meeting with the Staight-8's upstairs, I was the guy with the PP 6B4G's on rusty Dynaco Mk II chassis.
My my, the years fly...
Bean, Whats your name? and Yes I remember little about your system I mostly was downstairs, In those days I had much interest in learning about everything LOL, nowa days I have settled in IMO not much more to learn I have heard many horn systems(most kinda sucked) but When I visited Chris's from Teres audio his old room and setup with his old edgar horns they were very good, but still shy short of what I consider the very best.
Anyways damn it was kinda fun in them days the people and the get togethers now the Internet has taken over no one wants to get together anymore :(
I guess most of the chicago horn club guys have gone.
I'm Kevin (not the Kevin that had the online DIY business). Wasn't around much in the latter days of the Chicago get-togethers, life just got busy. There are still folks hanging around here, tho.
I also took my speakers to the first MAF when the Chicago club had a room. Vintage "hi-fi furniture" cabs w/Edgar salad bowls propped on top.
I see some folks I know every year at AXPONA. I'll be there this year on Friday.
Paul and all...
I have not acquired an amp as yet . I felt that the speaker would be more difficult to source .
This thread seems to have gone in two different directions .
Camp 'A' is positioned in the big box/big driver thinking .
Camp 'B' is with a smaller box/smaller driver thinking .
Both seem to be able to hit the requisite efficiency requirement .
Camp 'A' will definitely move more air and take up more space . Maybe better suited to classic rock and symphony orchestra .
Camp 'B' seems like it would finesse and 'fit in' easier . Maybe better suited to female singers and small venue jazz .
I realize that this is a broad generalization but could it be useful for deciding which camp to pursue ?
Small boxes simply will not equal the efficiency of larger boxes.
