  1. I have a pair of Dynaco A25 loudspeakers that I use with an old Marantz 2230 receiver . Love the mellow sound this combo produces . It's music to my ears . Recently I passed up a pair of Dynaco A25 XL loudspeakers at the pawn shop . Went back to purchase them and they were sold . Now I'm wondering if I let a great pair of speakers pass me by . Has anyone ever done a listening comparison between the two speakers ? Mine has alnico drivers , the XL I believe has ceramic magnets . Is there a difference between the sound of the alnico speakers and the ceramic versions ? Comments appreciated .
  2. Can someone please list the AR speakers that used alnico magnets in their drivers . Lately I've been listening to a pair of AR3 loudspeakers and I really like their tonal color . I would like to purchase a pair of old AR alnico driver loudspeakers . Anyone knowledgeable about these older AR alnico speakers please list them . This would be a great help when looking for a pair . Thanks ! P.S. include other box type vintage loudspeakers from other manufacturers that use these type magnets . Some people say there's no difference in the sound of alnico and ceramic magnets . This might be true but I like what I'm hearing from these old AR3's .
  3. The AR-303 is the newer version of the AR-3a yet the older speaker has a cult like following . The newer speaker seems to be popular also . You rarely see them for sale . I have a pair of AR-303's but I've never heard the older 3a's . Julian Hirsch once did a comparison of these two speakers and the 303 measured better in every way . From the tenoir of the original review it seem like he even preferred the sound of the 303's over the 3a's . Am I missing something here ? What's so special about the 3a's ? If this speaker is better than the 303's maybe I should be searching out a pair . Your comments will be greatly appreciated on this AR-303 and 3a issue . Thanks !
  4. What are the opinions on phase/time coherence in loudspeakers here ? There are some companies praising the benefits of a time coherent speaker over a non time/coherent design . I've never heard such a speaker and was wondering if this is really such a big deal in loudspeakers . Any opinions on the subject would be appreciated . Thanks !
  5. Is anyone getting great imaging from their AR-303 speakers ? If so what is your space between each speaker in feet ? What's the ideal placement for the best inroom imaging . My room is sort of small for the speakers ( three feet between the speakers ) is definitely not doing the imaging thing .Room size is 11x13 feet and crowded . Will move system to a larger room soon (15x24 feet ). I've heard that these speakers need a larger room than the monitor type speakers . Any info will be appreciated . Thanks for posting !
  6. I have a few questions concerning the AR-303 loudspeakers . #1. Is it worth the effort to upgrade the crossover parts in this speaker ? Is there an audible difference ( stock vs upgrade )? # 2. I took a look at the crossover network in my speakers . Does anyone know the exact values of the various crossover parts for this speaker ? If so please list them . I realize this is asking much but info will be greatly appreciated . Thanks !
  7. Which AR loudspeakers had the best imaging and coherence ? Also can someone comment on AR's view about stereo imaging in their speakers . How does one get great in-room imaging from AR loudspeakers ? I have a pair of AR-303 that I'd like to use for serious listening . Your thoughts appreciated . Thanks !
  8. I'am looking forward to hearing from Mr.Tyson on this subject !
  9. Just curious as to what type plywood these classic AR speakers are built from ? Is there a reason why AR used plywood to build their cabinets as opposed to fiber board ? Can this type plywood be found today ? One more question . Plywood vs mdf , which is better to build acoustic suspension cabinets and why ? Thanks !

    AL115 ???

    I've owned several pairs of Allison loudspeakers over the years. The AL-130,120 and 115 . All Allisons have solid-braced cabinets(quality speakers) .They image extremely well, you don't need to be in a hot spot to experience stereo with them . The Al-115 cost me $400 for the pair in 1990 . The AL-130 was the best ! Sorry I ever sold them . The AL series was a great speaker line . You can't go wrong with Allison loudspeakers .
  11. Is there an ideal room size that the AR-303's performs at its absolute best in ? I have no problem getting excellent sound from my AR-228's in the 13 ft wide x 15 ft length audio room. I find that the larger speaker is over whelming at times in the deep bass in this room. The overall sound is silky smooth but bass is definitely a problem here . If there is an ideal room size please offer suggestions .
  12. Ever since AR got away from making true acoustic suspension loudspeakers I haven't been back. Recently I saw several bookshelf speakers for sale by AR( Christy design ? ) at very cheap prices $89 -$160 pair. They are ported box loudspeakers. Has anybody here ever heard the new AR ported loudspeakers? Do they still have the neutrality of response of the classic speakers or is it a waste of time looking at these loudspeakers ?I can't tolerate spectacular sounding, bright treble and edgy mids in a speaker. I don't want to spend money and be sorry later.
  13. I've read several posts here that AR loudspeakers are used as studio monitors for mixing purposes. Can someone elaborate on what it is that makes one loudspeaker highly suitable as studio monitors and others not worth looking at. JBL has been making pro studio monitors for decades.(1) Is it really possible for speakers like the AR-2, 303, and other AR's to be as accurate as the JBL-lsr32's and other pro loudspeakers ? (2) Can a pair of AR loudspeakers really tell you everything you need to know when mixing ? Those users who are currently using AR loudspeakers as studio monitors please let me know of your experience with these speakers as monitors.Are they telling you the truth? I need a pair of studio monitors but if I can get by with a used pair of used AR speakers I will . I have a small home recording studio and cost is a major factor.

    EPI 100's

    Thanks for your response Steve ! :-)
  15. Hey ! What happened to the AR 303. Is it not a great speaker from ARs' past or present? To my ears I think it betters the AR-3a.Just my opinion.
  16. Thanks guys for answering my last post! I have another question .Does anyone know the type box assembly technics used on the AR 303 and 302 speakers? Is it a simple butt joint or lock mitered cabinet?
  17. I realize that the AR-303 is a remake of the AR-3a's. Due to the fact that the designer chose to go with the AR-303 and not the actual AR-3a with its' offset drivers and bullnose cabinet,does this mean that the AR 303 is the better cabinet design? Could the designers please elabarate on their decisions.

    EPI 100's

    This question is for technicians or engineers. Has anyone ever seen a graph of the EPI 100's frequency response ? At what points does it deviate from flatness ,what frequencies tend to stand out?
  19. AR classic loudspeakers measure flatter than many loudspeakers today. Could someone who is well versed on AR loudspeakers explain why flat response is so important to accurate reproduction or reproduced sound?
  20. I've come to the conclusion that the classic speakers by AR are very accurate indeed ! Much more neutral sounding than the vast majority of speakers produced these days. I have a question for long time AR fans of technical knowledge. What bookshelf speakers manufactured by AR would qualify as having the flattest or most neutral frequency response? I need an affordable book shelf speaker for use as a nearfield studio monitor.
  21. I'am looking to purchase a pair of AR 28 speakers.I already have a pair of EPI 100 speakers. I'am into the neutral response aspect of a loudspeakers performance. Can anybody who has experienced the AR 28's give me some input as to which speaker is the most accurate as far as frequency response when compaired to the EPI 100's ?
  22. I just finished building new cabinets for my EPI 100 speakers using mdf material. I would highly recommend that owners of this speaker build a better box made from mdf! This material is totally superior to the stock particle board.Anyway with drivers firmly fastened in the cabinet(screws hold much tighter now) they sound more open,bass seems to hit harder or is more taunt. It seems like their is less bass resonance,bass is solid and free of any signs of boom! .I'am no engineer,all I know is that it's hard to believe the difference a super sturdy cabinet and ultra thick baffle makes in the sound of these speakers.The down side is that the speakers now weigh almost 40 lbs each,a significant weight increase.I now believe that a speakers cabinet is more important than other aspects of the design.Not to down play other parts of the speaker but if you have a tremendously sturdy launching pad for the drivers this will cut down on all sorts of internal resonances that affects how a driver sounds.The performance is not earth shattering but side by side with the old cabinets the differnces in performance really stands out.As long as you preserve the internal volume of the original speakers this will definitely work ,and is a worthwhile project.Also my speakers function as a pure acoustic suspension design now. Internally all pores within the mdf was sealed to prevent leaks,also all internal joints were sealed with rubber silicone.I plan to do another project soon by building cabinets for a pair of new KLH speakers .
  23. I'am in the process of building a new pair of cabinets for my EPI 100's.The only difference is I'll be using 3/4 inch mdf to build the cabinets.They'll have the same internal volume but will have a 2 1/2 in baffle and a figure of eight brace dividing the internal volume from top to bottom of cabinets.I read that speakers will sound better if the cabinets are super solid. I'am not finished with the cabinets but would like some input.Is this a worth while project for an individual in search of great sounding speakers.Will these new cabinets make for a better sounding speaker system?Please comment!
  24. I just purchased a pair of JBL lsr32 midfield studio monitors because I was told by members in the recording profession that no home speakers are nowhere near as accurate as these. Then I noticed response charts for AR 303a's in room measurement. The response graphs looks almost linear. I 'am now in the process of returning the JBL reference monitors and save myself some money because I now believe my AR 303's would serve as reference midfield monitors of equal accuracy. Am I making a mistake here? Any comments would be greatly appreciated.
  25. What is the useful lifespan of the rubber surrounds used in these large AR speakers? I've been told that foam surrounds will last anywhere from 5,10 or 15 years.Anyone who has experienced how rubber surrounds deteriorate over the years please comment.
