890C's $150 Texarkana

I understand the 406's are the real draw with these but how are the Heppner drivers--do they at least approach the Altec sparkle that many of us are used to (spoiled by?) or are they pretty lame?

zillions of these are in magnavox consoles.

sound good with lo power tube amps,

which is what they were designed with/for.

they are not the same as an large compresson driver, and don't sound like one .

tomt is right. The large Altec horns are more forward. The Heppner crosses higher, so doesn't have the "in your face' mids, it's more laid back. McGee Radio sold boatloads of Heppners back in the day, they were a fave of the DIY market, known as "Hepp horns"

They do sound good.
