    I grew up listening to my dad's ESS AMT1B's and that is definitely not a heil tweeter. The tweeters go for $300 a pair all day long on ebay so if you ever do see any down in Atlanta for cheap let me know because I'll need some spares for when I inherit my old man's.

    Hope you all are doing well, try to call soon.

    Putting real AMTs in a plastic RCA speaker would be like mounting a jet engine in a Yugo. :lol:

    Ha! I remember those. Back when I was just getting into home theater, I gave those a try along with the matching center. I remember being pleasantly surprised. Back then, Radio Shack sold some quality stuff. These days, though...

    Linaeum tweeters don't look the same as Heil AMT tweeters. I don't think it's the same design.

    The Linaeum tweeter is more like a planar - and nothing like a Heil AMT. The Lineaums aren't bad - although a little strident for my taste.... and the 'real' Lineaum branded drivers were much more substantially built than the R/S drivers.

    The Heil drivers are still/again available, not cheap, though.

    (well, looks like they're on backorder... but at least - in principle - yez can buy a pair...)

    Memories.... Kind of makes me want to dig out some of my R/S collection and take them for a spin down memory lane. They used to make some pretty decent stuff. At least that's what it seemed like as a teenager. I remember one of my earliest memories of hearing a nice rig. A buddy's dad had a huge Sansui receiver on a pair of Mach 1's. The guy also had a gigantic speaker from a juke box. man I thought he was cool.

    I've had both the Optimus LX-4 and LX-5 with Linaeum tweeters. Neat stuff with no relation to Heil.

    I have LX-5.
    They are not bad but need a subwoofer.
    A lot of flickering sound from the tweeters.

    I have some of the later model RCAs with that Linaeum tweeter and a supposed yellow kevlar woofer. They don't make "any" flickering sound, you must have a defective set?

    Hold on... there is an app for it. I mean there is a word for it.
    Details.... lots of details and sizzles from that tweeter.
    Now don't ask what sizzling sound is. :wink:

    they are a bit sizzly, truth be told.
    I have a pair of the add-ons that I bought on close-out - the stock XO (probably an NP electrolytic from some third-world country ruled by a despotic dictator) doesn't help matters, probably.

    The pure-play drivers made by Lineaum were certainly much more stoutly built - and may well sound much better; I've never stumbled across any, though (at least to date).
