Guest mircen Posted November 9, 2005 Report Share Posted November 9, 2005 Hi,I am new member and it is my first post to this forum.I have a pair of AR-48s loudspeakers (refoam the bass and midrange speakers) and they play great (see the attachment). Refoaming the midrangrs was a hard expirience, bacause it's a problem to find 4,5" foam ring here, so have to use 4" ring, but it O.K. now.As a part of my "vintage" system, they are connected to Marantz 1090 amp (1978) rated as 2X45W RMS, which seems to be a little bit underpowered amp for these speakers. That’s why I get a pair of AR-17 (1977/78) which (I think) will be more suitable for "1090". But I found them without tweeters. I refoam the bass speakers and now I am looking for tweeters (identical with AR-18 tweeters). Has anybody picture of those tweeters to send me, how I will be able to recognize them on some "market".

johnieo Posted November 9, 2005 Report Share Posted November 9, 2005 >how I will be able to recognize them on>some "market". >Regards,>mircenHello mircen:Many of these tweeters look similar from the front-- a small dome (called either 1-1/2 or 1-1/4 in) in the center of a 3-1/2" flange. When looking on eBay or elsewhere, it is best to ask for a photo of the reverse side, and examine the AR part number.Quoting from Jan. 1, 1979 Teledyne-Acoustic Research price list:AR Part # 1200014-3, 1-1/2-in pressure highrange, 3 oz. magnet (AR-7x, AR-17, AR-18).Quoting from the Nov. 1, 1986 price list:AR Part # 1200014-3 1-1/4" highrange (AR-7, AR-7x, AR-18, AR-25)Be careful; in 1979, AR used a #1200005-0 for the AR-7!best stick with part number, and not the seller's description of what speaker the driver will fit!!!!happy hunting!

One might see an inaccurate eBay advertisement that states the tweeters for sale are from an AR-18 (same as used in AR-17), when in fact the items for sale might have been from an -s, -b, or other newer version of the 18. Best to ask for a picture of driver backside showing AR# 1200014-3. Link to comment Share on other sites More sharing options...
