    Okay, these AR12 are awesome!

    This makes sense. A properly working AR12 with its 400hz crossover should sound very similar to an AR5 and better if the AR5 had a degraded tweeter. Actually, except for bass extension, it may have been the best sounding of the ADD series. AR never had a lower crossover in any three way until the Connoisseur series.

    Original replacement mids and tweeters are getting either scarce and/or expensive and this is a way around the issue. In your opinion how do they compare with the originals or other 12 inch ARs?

    1966 AR3 rescue

    you need to read this thread.
  4. I don't know if impedance changes with age or if so whether it drifts up or down. Diff in 86 in 85 db is imperceptible to the ear but with the combinations under discussion practical headroom is not more than around 8db at 2 meter listening distance so 1db difference is 12% to 15% of headroom. Most non-orchestral music has dynamic range of not greater than 6db whereas the 1812 performance referenced above is 12 to 15db. 86db avg spl at 1watt with AR5s would be plenty loud for me at two meters and would require 2 watts sustained. To cover a 6db peak I would need 8 watts in reserve. To cover a 15db peak you will need 64 watts...................more than 3 times the Fisher 400 rated power. My point is, many speakers will work ok , just don't expect a lot using modern recordings with this level of power, unless you get Klipsch Horns or L300 JBLs for example. Aadams
  5. Out of curiosity I checked and honestly, to my surprise the 15 is the least sensitive of the entire ADD series. Maybe an AR4 is more sensitive.
  6. You should supply photos of front and back of the speakers if you want more help.. If they are ARs they are no earlier than 1979 IMO.
  7. AR5s and 91s are very near identical sensitivity.
  8. Arken are you there? You asked as a broad question and received some good general opinions. Do you have a thought now or just stirring things up? Aadams
  9. RE the AR 5s ...........I ran AR5s with an 18 watt Sherwood for while in a 1000 cft room. What can I say? It works for narrow dynamic range music and background. Not very satisfying. It really depends on room size, listening distance and music preference but the parameters for a good experience will be very confining at 30 watts. My thumbnail estimate says, listening at 6ft, you will have maybe 8 db of headroom at 86db spl, which is not much with modern recordings. IMO do what ra.ra. said. Find some AR 2ways. Adams

    AR5 pots bypass

    Ditto everything Kent said above plus if your AR5s have Sprague Compulytic capacitors they probably don't need to be changed. Get the speakers completely working, including either a tweeter rebuild or Hi Vis, before you judge whether the caps need changing. Adams
  11. I can't find where you told us the crossover frequency.

  13. The AR5a Improved. Must be bi-amped with external crossover.
  14. Never mind the reason, but not by choice do I find myself with a lot of listening time available and I have been listening a lot to these refurbed AR5s. I have had my 5s for five years and as recently as 3 months ago viewed them as a less capable AR3a for the chamber music and acoustic jazz /pop/folk crowd. My current opinion is AR probably never made a system that sounded better in the voice band and above, including the AR9. This is just my opinion, but it also means there are not many speakers equal to or better than an AR5 which I would now put above a 3a for quality of sound in the low mid-range, where most musical sounds originate.
