Sono nato e cresciuto con le AR10 Pi-Greco di mio padre, c'erano quando sono entrato in casa con pochi giorni di vita e ci sono ancora oggi dopo 40 anni. Un po' di manutenzione con la riconatura dei woofer e la sostituzione della cavetteria interna ma per il resto sono praticamente "come nuove". Mio padre purtroppo non c'è più ma le sue AR10 Pi-Greco continuano a suonare e a tenermi compagnia tutte le settimane insieme al resto dell'impianto stereo che con passione aveva assemblato un pezzo per volta. Pre e finale Carver, giradischi Thorens e lettore Cd Aiwa Excelia. E' un impianto sicuramente "vintage" ma è il "suo" e tale mi piace che rimanga. ^_^

[@MissJuliettes]

Stefano Massobrio che Insieme stupendo! Ho appena installato le mie pi-greco, con lettore vinili e stereo Pioneer. Anche un lascito famigliare .. Suonano meravigliosamente! Mi incuriosiscono i bellissimi rialzi per le tue pi-greco, sono acquistabili o li hai creati tu? Complimenti !!! Giulia

[@gino3286]

non sono riuscito a trovare foto del crossover originale ma se sui medi ed alti ci sono degli elettrolitici andrebbero cambiati con dei plastici ... il suono si apre piuttosto. Ho letto che qualche volta anche le resistenze possono cambiare valore ma basta fare una risposta in frequenza e vedere se ci sono buchi esagerati. Il woofer ha bisogno di tanta corrente. Io le ho sentite suonare alla grande con un finalone di Aloia. Reggono tanta potenza davvero. Che bordate con la sinfonica.

[@giuseppe5580]

@@gino3286 venivano utilizzate capacità "plastiche" che, per la tecnologia dell'epoca, erano molto ingombranti. Nel caso fossero presenti condensatori elettrolitici sarebbe sicuramente opportuno sostituirli tutti e, come dice giustamente Lei, meglio utilizzare condensatori in film plastico. Infine, è concettualmente errato pensare che sia necessaria molta corrente per pilotare quel tipo di diffusori; la corrente è necessaria per pilotare carichi ad impedenza molto bassa ma quel tipo di diffusori aveva (ed ha) impedenza che difficilmente scendeva sotto i 5 Ohm. È necessaria una buona amplificazione in termini di potenza, questo sì, per il fatto che i woofer dell'epoca avevano scarsa sensibilità.

[@gino3286]

@@giuseppe5580 grazie mille per la gentile risposta e interessante spiegazione Ricordo un amico che le aveva e di ostinava a pilotarle con un valvolare non potente Ottima gamma media zero bsssi Ma diffusori magnifici Credo che sarebbero ancora attuali saluti Gino

[@iltecnicog983]

@@gino3286 assolutamente d'accordo con Lei. Vilchur (co-fondatore della AR) era uno dei pochi ingegneri che sapeva veramente il fatto suo nel campo dell'HI-FI. Tra le mie esperienze annovero la riparazione di una coppia di AR-3 che montava gli stessi tweeter e mid-range delle 10 e PI-GRECO; bassa efficienza ma suono veramente raffinato per l'epoca (non dimentichiamoci che i primi esemplari di questi altoparlanti "Made in U.S.A." risalgono agli anni '60!). Vilchur, rientrato in patria (Svizzera) ha poi fondato la ROWEN e, utilizzando gli stessi altoparlanti della serie 10, 2a, 3a e Pi-G, ha realizzato una serie di diffusori "particolari" (modelli: R1, R2, R3, R1+1) dalle caratteristiche tecniche e sonore veramente sbalorditive. Le R1, di cui ne posseggo una coppia, sono diffusori in sospensione pneumatica con efficienza dichiarata di 91 dB e risposta in frequenza a partire dai 30 Hz. Il filtro crossover è del tipo "serie" (una vera chicca perché raramente i costruttori si cimentano a realizzare filtri del genere in quanto difficilmente valutabili, dal punto di vista del funzionamento, a livello teorico). Nel caso lo avesse o sia in grado di reperirlo, se Le può interessare, sul N° 75 di Audio Review del 1988 è pubblicata una bella prova delle ROWEN R1 in mio possesso. La avviso, però, del fatto che lo schema del crossover riportato non è corretto; i valori delle capacità (a parte una) sono completamente diversi. Cordfdiali saluti.

[@override39]

wao nice sound .i enjoy every sec of the sound.thank you for sharing

[@socksumi]

AR 10pi is the model. The mids and tweeters were much improved versions of similar looking drivers used on earlier the AR 3A and AR 5. This is a final evolution of classic AR 3 and AR 3a using phenolic domes. In my opinion the AR 10pi and AR 11 were far and away the best versions of that iconic design. The cheaper AR 11 was substantially the same speaker minus the environmental bass control. It's drivers sit a bit higher in the box which might be a plus in some setups.

[@swinde]

I still have AR-3a speakers and still love them since 1970.

It still doesn't cost an arm and a leg, if you browse patiently for second-hand or even third-hand gear.

[@scottlowell493]

@@v.pintilie6691 That's not the point. In the late 80's, audio companies started charging arbitrary high prices. $13,000 for a two way bookshelf? None of the companies gouged that badly back in the day. So what if I can find gently used Hamilton bookshelf speakers for $6500, it's still an arm and a leg and way overpriced for what it is.

[@davidperry4013]

Q Acoustics 3020i less than 400 dollars and sound really amazing. I heard them in person and they already sound better than my old 601 series I despite being bottlenecked by a lepai mini amplifier. Mix a high quality vintage stereo receiver with these affordable bookshelf speakers. Your ears will be in heaven. The Q acoustics concept 500 is a 6000ish dollar floorstanding speaker but, attention to detail in the engineering of these speakers makes them worth every penny and rival the sound of sonus faber aida speakers that costs over 100gs.

[@marvinmurakami8828]

If your talking about the dollar amount that these components listed for back then, you'll have to multiply that by 4 or 5 times for the equivalent in todays dollars to account for inflation. Minimum wage at that time hovered around 2 dollars an hour. I think very good sound is attainable cheaper than ever.

I'd love to put my aDs 910s vs these AR 10s. The 910s also have dome mids/tweets plus dual 10.5" drivers installed into their own separate bass enclosures inside the cabs, thus the 100lbs/each. ( 130lbs with the stands ) The 910s are my end-gamers.

great amplifier, great speaker, eargasm

[@dfddwm]

Along with the AR9 and AR3 a pinnacle of sound reproduction and hi fidelity. You are a very lucky man. I have the AR12. The mids I think are same, sophisticated ferro fluid with delicate surrounds. You can top the ferro up if necessary as it dries up. The tweeters are different (AR Vntage told me!). You have the 12" woofer and controls on a tuck away front panel. I have exactly the same stands that were made for this model. When new they sported an incredibly chic black foam grill which unfortunately crumbles to nothing over time. I had new cloth replacement grills from USA which fit well and are sturdy but somehow don't seem to go with the very clean lines of the boxes. I find these wonderfully transparent and suited to classical music especially the midrange and after tones of wood and string instruments and vocal. Cheers David London UK PS mine came from the Luton area AR factory and had one previous owner, a manager at the factory with all the invoice, consignment and manufacturing paperwork plus AR brochures.

[@sosonic12000]

It's very difficult to beat the Sansui sound as it's tireless listening and keeps the lucky listener interested with great headroom and dynamic if you get the correct speaker pairing. I've put my Marantz 2265B aside and reconnected my Sansui Sx 1130 paired with Jbl's Lx 66 and honestly people it's the sound I've searched for my whole life. Crisp highs through the titanium tweeters snare drums are amazing a great punchy bass and mids deliver exceptional separation. And the best bit you don't need to break the bank at all as I believe these are under the audiophile radar.....And I've had loads of equipment over the years. You can get fantastic sound for cheap...can be an expensive hobby trial and error as I definitely know...Great track by the way Chuck Mangione

Tra i miei diffusori è presente una bellissima coppia di ROWEN R1 del '91, diffusori progettati e realizzati da Edgar Vilchur che è stato il co-fondatore dell'americana AR e che, ritiratosi nella sua terra natale (la Svizzera) ha appunto fondato la ROWEN. La R1 è caratterizzata dal fatto che gli altoparlanti utilizzati sono esattamente proprio gli originali AR che venivano utilizzati per realizzare le AR-10 o le PI-GRECO (tweeter e mid-range), mentre i woofer sono da 20cm di diametro, quindi piu piccolo (per ogni diffusore ne venivano impiegati 2. Per chi fosse interessato, è presente la prova sul numero 75 di AUDIO REVIEW del 1988 ma vi dico già che lo schema del crossover non corrisponde al vero (spesso questo è voluto proprio dal costruttore e non è colpa dell'editore).

nice sounding and lively speakers, a tad bright though. Will be interested to hear the bigger speaker behind it.

[@lp5913]

A matter of choice, this brightness. I have a pair myself and you can adjust the low, mid and high on the speakers using three switches situated on top behind a cover. And you are right, the tweets are pretty high in performance! I, for one, have the tweets on the lowest position -6db. And woofs and mids on normal. It creates a warm dark sound, like you have in a theater. Again, it is a matter of choice. And, I have to add, he is playing a cd here, which also explains the brightness. Vinyl is a total different story, you should here a 70's record on these baby's! I haste to say that new records also sound very, very well! (Amp: Creek 5350SE, Thorens turntable with Nagaoka JN-P110 needle. Just to create the picture.)

[@new-knowledge8040]

See imgur . com/a/VIARZn5 ( Remove spaces ) With a little bit of repair work, my old speakers just kept on working. I bought the AKAI 630D reel to reel tape recorder back in 1978. MY DENON DCD-900 CD player that I bought in 1987 is still going strong as well. It started to randomly skip during playing, or miss certain songs all together. That was due to the LED CD scanner not being able to keep up with the proper scanning of the CD. So all I had to do was add a couple of drops of electric shaver oil to the mechanical gear system, and bingo, it was working as good as new again. The speakers are what I built all by myself back in 1978. It is amazing that after all these years they still sound so good. But I have to be careful. The police once showed up due to a sound noise complaint. There is plenty of volume coming out of these old babies. I did have to once eventually rebuild the woofers though. Due to age, the rubber rings that attach the centre cone to the outer metal chassis, had literally turned to dust. But for a mere $27, I purchased new rubber rings for the two woofers. It took about one hour and a half to repair each woofer. But it was worth it, and suddenly they had came back to life again, all back to being as good as new again.
