Ar 90 acoustic research amplifier
Last truly visible Acoustic Research from the beginning of the Teledyne ownership and before the subsequent various ownerships and fortunes. Not that AR had been as successful in the s as it had been throughout the s but at least it had been present. The s and s turned out to be more of a disappearing act improvised in several steps The AR9 is a very vertical 59 kg four-way loudspeaker with five drivers. The two 30 cm drivers are placed on the sides of the enclosure to keep reflected sound-cancelling waves above Hz - big room necessary because that makes four 30 cm drivers outputting long waves of sound! The goal of this was to avoid the " wall dip " : where walls' reflections cancel out some of the bass output, making the transition between low mid and top of the bass range difficult and straining the amplifier's output.

Acoustic Research AR Amplifier Universal Model AU
Read times. Pages: [ 1 ] Go Down. IanATC Jr. Member Posts: » Systems. I have decided to post this because so few speakers now are sealed. The majority of the market is ported in some way. I think sealed offers accuracy, detail and speed advantages over ported. But this is not about sealed vs ported, as I have heard good examples of both. Does anyone have information about 80's and 90's AR speakers? Thanks and cheers.
Quote from: IanATC. Thanks for the reply! I have an additional "suspicion" if you want to call it that. Not to mention treble extension doesn't seem all that good. I only got to hear a small set of AR bookshelf speakers. Two way, with a 8" sealed woofer. It was mid 80's vintage. I think the principals are excellent. And now that solid state has come a long way, we have plenty of power to do them justice. I'd like to hear those AR's again, but with a stout wpc pushing them.
I'd like too see what they sound like when really backed by topnotch gear. Do the AR and 's count? These were 2-way bookshelves I bought at Circuit City many years ago. The had a 6. I would not say they were warm, though. Kind of sterile and possibly harsh. However, they held together exceptionally well at extreme volumes.
I had them connected to an Onkyo integrated amp These were replaced by DCM Timeframe's They can be used on a variety of applications. However, warm and pretty they are not. They image OK, the 's had hollow sounding bass and the 's were much richer in midbass but, didn't have the punch of the 's for midrange.
I've gotten rid of both pairs but, don't know if this is the same Acoustic Research that people talk about. Quote from: Carlman. Quote from: DVV. As for the "BBC sound", and this may surprise you, although there weren't many UK designed and built speakers I really liked, I do feel there is a lot to say for the BBC sound as a concept - and unfortunately, not all, not even enough was said about it.
The Kef Fact: many ofn the best American speakers from the 70's and 80's used KEF drivers. In general, I feel UK speakers up to say were slow and somewhat detached for my taste, although they were by and large detailed and there was much work in progress to achieve high levels of precision.
There were exceptions to this, of course - for example, I would have picked up a Spendor anytime but they were reflex! The US scene was very much different in general , they preferred efficiency and liveleness, and wanted seamless integration from top to bottom at the expense of absolute clarity and precision. Just think back to speakers like JBL's L, a home derivative of their legendary monitor.
I cannot look back on those with the same reverence. The L had a paper cone tweeter. It was beamy at certain frequencies, and boomy at others. It was by far and away more coloured than the KEF from that same timeframe. They were not seamless, nor lively. The sound like midfi to me. As for your comment regarding horns and Klipsch, well, your view is just one of many possible. I could now say that these were indeed up-and-go speakers, sometimes in-yer-face, but that they were more efficient and faster than somewhat slow UK speakers.
More coloured and shouty like a public address system? Midfi, not hi-fi. The big horns had a demonstrated time delay. Even using some of the softest and most romantic valve gear, klipsch still screams bloody murder.
If you were to replace what you had with a Klipsch, and live with it for say a month or two, what do you think your reaction might have been when changing back to UK speakers?
You might have them thought them slow and "lazy", despite greater precision. Just my view. I can only look back to a handful of pre 90's speakers with any joy. Spica, rogers, kef. They all had a more romantic sound than by todays standards. Compared to my ATC, most speakers will sound syrupy and slow, but that is a preference in itself that many people have.
How many times have you read the phrase: "I could listen to it for hours on end without fatigue" That should NEVER be stated of klipsch. Sa-dono Full Member Posts: » Systems. Quote from: Sa-dono.

Way back while most of you guys were in shorts, I used to own AR5 speakers, and I loved 'em. I agree sealed enclosures tend to offer better bass control and resolution than most but not all vented speakers.
If you are wondering why this almost total changeover to reflex, the answers are simple. Reflex offers better overall efficiency, it provides for somewhat lower cutoff -3dB frequency that sealed, and last but not least, they were in vogue at one point. However, sealed will offer more extension than relex as its deterioration is slower than that of the reflex and it will offer less to much less phase shift in the bass, which usually accounts for its greater clarity.
What's to say? AR invented the principle in and pushed it really far. At one point, people e. Marantz, Ortofon-later-turned-Dynaudio, etc were offering sponge bungs you could insert in your bass reflex vent and turn the speaker to some sort of sealed. Of course, this never really worked well, because the requirements for a sealed woofer are different to those of a reflex one, but it sure was a good marketing gig. I for one am sorry to see this worthy principle pushed aside, I feel there's a lot of mileage in it yet.
I cannot dispute much of what you say simply because it's all very subjective. I also don't like horms too much, not the common types but very expensive JBL and Klipsch jobs are a totally different matter. That least efficient are the most detailed is or was a very popular thesis in Britain. I always suspected this was launched by manufacturers of inefficient speakers who couldn't do efficient and needed some rationale to whitewahs their own failings. I don't think there's any direct link between efficiency and absolute clarity, although it stands to reason that the more efficient speakers will perform better with typica mid powered gear, while less efficient speakers will only do so-so.
The ARs I still have are used by my son. But push it a little harder, and of course, the more powerful of the two gets ahead. Still love 'em. They can be used on a vari Of course they do, Carl, why shouldn't they? Regarding your comment on them, I can't say I am surprised. My 94s were far from cheap in those days, they were the smallest of their two digit series, which was their flagship series of the day, headed by the big 9. I agree on holding together - same here, same ever since I first heard an AR.
This seems to be a family trait they all shared in their time.

The revamped AR brand is the latest aboard the digital music player bandwagon: is the AR-M2 a worthwhile addition to the choice available, or merely a latecomer? The revitalised — or is that reinvented? If, however, your problem is more with any portable player carrying so exotic a price-tag, a spot of context may be needed. That opens up some intriguing possibilities as, with the built-in Wi-Fi capabilities of the player, you could actually browse a website while you are listening to music. Having spent some time with the M2, that battery claim seems pretty accurate, although of course your mileage may vary according to the kind of headphones you use with the AR, and how loud you like to listen to your music. Not being a great fan of the kind of levels designed to pummel the brain into submission — I value my hearing rather more than that — I found the battery capacity more than adequate for all-day listening to everything from low-bitrate radio grabs right the way up to full-fat double-DSD recordings. I guess it all comes down to how you want to use your pocket player: I must admit I tend not to listen to music on my computer too much when I am travelling — when does one ever have time?
The Acoustic Research AR are very high precision devices, designed and built to tolerances comparable only to professional studio microphones. They far exceed the performance capabilities of the classic laboratory reference standard and AR LSTs. All of the modern technology in speaker design, as well as the most sophisticated of computer techniques, were used, not only in the development, but continually throughout their design and manufacture. The three most distinctive applications of this technology in the ARs are the Acoustic Blanket, the vertical, upper-range driver array, and the positioning of the two woofers, one on each side of the enclosure.
