  1. No, it isn't. Another thing for Mark's to-do list, I guess.
  2. Is this what you're looking for? It doesn't have a # on it, but is titled "Technical Data." AR-3a Technical Data.pdf
  3. Difficulty Joining CSP - Any Suggestions?

    Use cspsignup@genek.com.
  4. A 'NEW' look in AR badges?

    A trademark search turned up 50 different instances of "AR" registered by a number of companies. Three of these belong to the current owners of the Acoustic Research brand. The distinction between all of them is the style of the letters and accompanying logos.
  5. Were there any 4-way AR speakers other than the ones with side-firing woofers? I'm wondering if the reason they were 4-way was just that they wanted lower midrange coming from the front instead of the sides.
  6. With regard to the comments about "vocal heavy popular music," the jazz and classical music that AR's classic era ads leaned toward both had plenty of vocals. And if I'm choosing a vocal to use as a listening test source, I'll take Sarah Vaughn or Maria Callas over David Lee Roth or Axl Rose any day.
  7. Bought one pine early AR3a.....

    Looks great. What are you planning for a final finish (if any)?
  8. They're not mutually exclusive, except in cases where some manufacturer is still offering "non modern" products for sale.
  9. The original question specified "devices in today's audio market."
  10. Introducing the Bosar 903a tower speaker...

    Considering that the Bose doesn't have much in the way of vertical dispersion, it should probably be closer to listener height, in between the two ARs.
  11. Probably because it just didn't show up when I googled "3 way acoustic suspension speaker." Would it be enough just to use the subwoofer's low-pass, or would you want an external crossover that rolls off the lows on the satellites as well?

    The AR pine cabinets were definitely not decorative (i.e., "Cabinet Grade") plywood; if they had been, their outer plies would have been sawn rather than knife-cut and the grain would have been straighter, as it is in solid wood. However, I've never seen one that had visible knots or places where holes had been repaired with patched-in wood, so I'd guess that in today's grading system they'd be classified as "A-Grade Veneer Core Construction."

    Every layer in plywood is veneer, a thin sheet of wood made by sawing or knife-cutting a log. Layers of veneer become plies when they're made into a layered product. If you ever try to make your own plywood (I did this once as part of a class on wood product manufacturing and I don't recommend trying it at home - ever), you can't call a supplier and order wood in "plies," it's all veneer, and is sold as either "face" or "back" grade. "Back" grade veneer is what becomes the inner plies in finish grade plywood and all the plies in non-finish or construction grades, and of course, "face" grade is the prettier stuff that goes on the outside of cabinet and furniture grades. https://www.statesind.com/page/hardwood-plywood-terms https://www.statesind.com/page/veneer-grading The most effective bleaching agent for wood is sodium hydroxide (NaOH). It's nasty, caustic stuff that comes as a two-part product, you need to glove and mask up to mix and use it and after you've bleached the wood you have to neutralize the residue in the fibers with a mild acid like white vinegar, but it will definitely suck the color out of any wood it's used on. Thanks to their status as rare collectibles, the preferred "finish" of a pine AR is probably as close as you can get to completely unfinished wood. It's definitely a total flip on how woodworkers usually look at pine!
  14. The original question assumed that someone wanted "acoustic suspension sound" and was tired of trying to keep old speakers alive. So the "modern components" being referred to are whole speakers that can be bought today and somehow combined and/or manipulated into producing AR-like sound (either Classic or post-Classic, since no particular AR era was specified). We already have plenty of other discussions about suitable replacement drivers, and there's already an old discussion somewhere about how a new speaker could be built from scratch with new parts that could be revived if anyone is interested, but that would be at least as much work as trying to keep an old speaker alive. So let's not confuse this one.

    Use wood filler (make sure it's not the water based kind). Thin it with solvent until it's like heavy cream,brush it on and then wipe across the grain. Light sand after it dries.
