Tang Band 2145 in action

The best wide-bander is still probably the Altec 755 8-inch. 55hz to 8khz. 90+ db sensitivity. You will still need to add a tweeter for the last two octaves using a first-order crossover. The late Art Dudley owned a pair and reviewed them for Stereophile. He mounted each 755 in a large sheet of plywood - open baffle style. Bass as expected rolled-off at 55hz. Art liked the clarity of the midrange and didn't miss having a tweeter! He remarked that the 755 has a cult following that has driven up the prices. I sold my pair in excellent condition for $650 - about what I paid for them! Now I wish I hadn't done that! 

Good news is that there is an eBay seller offering reproductions of the 755. He is coupling the cone/frame to a larger improved motor (magnet/voice coil/spider). They look real nice! About $600 a pair.

Put each 755 in a one-to-two cubic foot sealed cabinet and you'll have something real special! Add a tweeter + cap on top of the cabinet for the last two octaves.

For my taste, the 756 with a tweeter is considerably better and more versatile (sounds good with more types of music) than the 755.  

Altec;'s are dateed.
You guys need to dump the old techs and get into the new high techs.
'hats off to Altec for what they brought you.
But we must move on to high fidelity.
This is not 1990, we are  2 decades into the 21st C.
Folks are free to stay with old low sens box types, if they wish,
I 'm with the chinese , audiophiles that dumped the low sens for the new highs ens wide bands.
In this case I think the chinese audiophile is either a  bit more honest, or a bit more smarter.
I think its both.
