  1. This is all great info. I have limited experience driving the 4 ohm AR's, only had some for a little over a year so far. Although I've had LST-2's forever, they are 8 ohms and anything I would power them with played well with them. I can say that when I was using an Onkyo integra A8087 integrated (100wpc) to drive 4 ohm LST's it would occasionally go into protection, but never get damaged. I wouldn't say this was an upgrade, but I am now using a Kenwood Eleven GX, 125wpc, rated to handle 4 ohms, but this thing has never missed a beat, and I prefer the way it sounds to the Onkyo. It gets hot by the time an album is over, but no issues yet. I've even connected two pairs of LST's to it and it survived, although I'm sure that is pushing my luck.
  2. I can definitely picture that since the 901's have that demanding eq curve, and I've had my amp(s) go into temporary protection, but nothing has blown up. Did the Nikko survive the abuse?
  3. I'm not disagreeing that obeying amplifier specs is important, however, has anyone personally had amplifier failure when cranking up to right before clipping? Just interested in hearing stories and what types of failures.
  4. For instance, the AR3a tweeter circuits use a 4 ohm nominal impedance driver, and a 15 ohm pot, with a 6mfd capacitor. When the pot is at full on, you are basicly 15 ohms pure resistance in parallel with a 4 ohm impedance (which will be calculated as resistance to simplify things, although this might disprove this question) Using fc= 1/(2piRC) for crossover frequency: with tweeter pot full on, the load would be calculated to 3.16 ohms, and with a 6mFd cap, cover frequency would calculate to 8.4KHz With the tweeter pot at mid point, you would parallel 7.5 ohms with your 4 ohm tweeter, then add the remaining 7.5 ohms of the pot, so this works out to be a10 ohm load. Now the crossover frequency works out to be 2.7KHz. Am I on the right track here? Would this be the "magic" behind the potentiometers versus L pads, which offer a consistant load, differing from the variable load as described above.
  5. Bring it on! I took the summer off too for the most part
  6. Very nice work, but I should have mentioned, I really am in search of original dust caps in tact...for no reason other than I like that look over a replacement one installed.
  7. I say casually looking since my speakers are playing very well, just that there are cosmetic issues from a previous reform attempt, and would like to eventually replace the woofers. Anyone have a pair or one for sale? Needing foam or not is no issue. I also have a nice AR9 style woofer I can trade for an AR3a woofer. Thanks!
  8. Help identifying AR4x

    The RS speakers
  9. Help identifying AR4x

    Those actually look almost identical to a pair of radio shack speakers I found curbside, just mind don't have the port. I'll post pics when I get home.
  10. 3a, LST & LST-2 tweeters

    Many thanks to Glenn for arranging the event, my first time at such a gathering and it was awesome. What a great excuse to drink some good beer and hear my favorite LP through Glenn's super fast ADS 910's and experience what a moving coil cartridge has to offer. I took some time off doing the tweeters in the summer months but I should pick back up as the cold sets in. Thanks again to all the great people I met and them sharing their systems, and also the use of that stunning Fisher pre for my Altecs (solid state ๐Ÿ˜Ž).
  11. AR-3F in AR-LST review

    Anyone have a link to the full article? thanks
  12. Hey Frank, all, that is my pair for sale, feel free to come check them out. PM me with any questions. Chris PS, if any board members are curious in hearing these, both LST pairs together, LST-2's, and are local, would be cool to demo some stuff and meet y'all. I was just weary of random people, hence the "no tire kickers" lol.
  13. AR classics: A+ report card

    I had the opportunity to see the Cherry LST's in person before the drivers were installed, absolutely stunning!
  14. Suggested pairing to the 2aX

    I use a Scott 222c, 24 watts/channel with my AR2ax's. Honestly, I can't find anything I don't like about the sound coming out of this setup. Decent amount of volume, and everything sounds so so smooth (perfect to me)
  15. AR2a, AR3 tweeter refresh

    Hello, no mids, I have really been focusing my efforts on the teeeters, they certainly are keeping my busy enough
